RecyclerView onClick

Question

Has anyone using RecyclerView found a way to set an onClickListener to items in the RecyclerView  I thought of setting a listener to each of the layouts for each item but that seems a little too much hassle I m sure there is a way for the RecyclerView to listen for the onClick event but I can t quite figure it out

This is what I do to reuse OnClickListener     public class TestAdapter extends RecyclerView Adapter lt TestAdapter MyviewHolder gt                                           implements View OnClickListener   in ViewHoder Take itemlayout s parent    public class MyviewHolder extends RecyclerView ViewHolder           LinearLayout linearLayout item           public MyviewHolder View itemView                super itemView               linearLayout item itemView findViewById R id linearLayout item                     in onBindViewHolder set tag as position      Override     public void onBindViewHolder MyviewHolder holder  int position            holder linearLayout item setTag position          holder linearLayout item setOnClickListener this           and in Onclick    Override public void onClick View v         int position    int  v getTag        switch  v getId              case R id linearLayout item                  do some thing with position               break

You can implement OnClickListener to your ViewHolder class  public static class ViewHolder extends RecyclerView ViewHolder implements View OnClickListener           public Item item          InjectView R id tv title          public TextView tvTitle           InjectView R id rl row          public RelativeLayout rlRow           public ViewHolder View v                super v               ButterKnife inject this  v               v setOnClickListener this                       Override         public void onClick View view                Log e  item title  item getTitle                       And onBindViewHolder set your view holder s item  public void onBindViewHolder ViewHolder holder  int position            holder tvTitle setText objects get position  getTitle             holder item   objects get position

You can pass a clickListener to Adapter   In your Activity   private View OnClickListener mItemClick   new View OnClickListener           Override     public void onClick View v            Intent intent   null          int position   list getChildPosition v           switch  position                case 0                  intent   new Intent MainActivity this  LeakCanaryActivity class                   break              case 1                  intent   new Intent MainActivity this  ButterKnifeFragmentActivity class                   break                    if  intent    null                MainActivity this startActivity intent                        then pass it to Adapter   MainAdapter mainAdapter   new MainAdapter this  mItemClick     In Adapter s onCreateViewHolder     Override public MainAdapter ViewHolder onCreateViewHolder ViewGroup viewGroup  int position        View itemView   activity getLayoutInflater   inflate R layout main adapter item  viewGroup  false       ViewHolder holder   new ViewHolder itemView       itemView setOnClickListener mItemClick       return holder

This was so hard for me to have on item click listener in the activity and also to have click listener for single view of the item that will not trigger on item click listener  After playing around with Jacob Tabak s answer I respect his answer for on item click if no other touch actions inside item are presented   I have a custom OnClickListener interface that have on item click event which holds the clicked item s view and the item position from the adapter  I present an instance of it in the constructor or it can be with setter  and attach it to the view holder container click listener   I also have other click listener in the Adapter Can be in the view holder  which will handle current View click from the container    public class MyRecyclerAdapter extends RecyclerView Adapter lt MyViewHolder gt     private ArrayList lt String gt  mData  private OnItemClickListener mOnItemClickListener   public interface OnItemClickListener       public void onItemClick View view  int position      public MyRecyclerAdapter ArrayList lt String gt  itemsData          OnItemClickListener onItemClickListener        mOnItemClickListener   onItemClickListener      this mData   itemsData      Override public MyViewHolder onCreateViewHolder ViewGroup parent          int viewType         View layoutView   LayoutInflater from mContext  inflate              R layout list item  parent  false        final MyViewHolder viewHolder   new MyViewHolder layoutView        viewHolder container setOnClickListener new OnClickListener               Override         public void onClick View v                mOnItemClickListener onItemClick v  viewHolder getAdapterPosition                            viewH lder button setOnClickListener new OnClickListener               Override         public void onClick View v                  do button click work here with                mData get  viewHolder getAdapterPosition                             return viewHolder      Override public int getItemCount         return mData size         In the activity you need to initialize the adapter by passing instance of the OnItemClickListener  public class FeedActivity extends ActionBarActivity     Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState                 RecyclerView recyclerView    RecyclerView  findViewById R id my recycler view                   MyRecyclerAdapter adapter   new MyRecyclerAdapter new ArrayList lt String gt     new OnItemClickListener               Override         public void onItemClick View view  int position                    list item was clicked                        recyclerView setLayoutManager new LinearLayoutManager this        recyclerView setAdapter mFeedsAdapter       And my ViewHolder  public class MyViewHolder extends RecyclerView ViewHolder    public Button button  public View container   public MyViewHolder View itemLayoutView        super itemLayoutView        container   itemLayoutView      button    Button  itemLayoutView findViewById R id button

I m aware there are a lot of answers  but I thought I might just provide my implementation of it as well   Full details can be found on another question I answered    So  to add a click listener  your inner ViewHolder class needs to implement View OnClickListener  This is because you will set an OnClickListener to the itemView parameter of the ViewHolder s constructor  Let me show you what I mean   public class ExampleClickViewHolder extends RecyclerView ViewHolder implements View OnClickListener        TextView text1  text2       ExampleClickViewHolder View itemView            super itemView               we do this because we want to check when an item has been clicked          itemView setOnClickListener this               now  like before  we assign our View variables         title    TextView  itemView findViewById R id text1           subtitle    TextView  itemView findViewById R id text2               Override     public void onClick View v               The user may not set a click listener for list items  in which case our listener            will be null  so we need to check for this         if  mOnEntryClickListener    null                mOnEntryClickListener onEntryClick v  getLayoutPosition                         The only other things you need to add are a custom interface for your Adapter and a setter method   private OnEntryClickListener mOnEntryClickListener   public interface OnEntryClickListener       void onEntryClick View view  int position      public void setOnEntryClickListener OnEntryClickListener onEntryClickListener        mOnEntryClickListener   onEntryClickListener      So your new  click-supporting Adapter is complete   Now  let s use it         ExampleClickAdapter clickAdapter   new ExampleClickAdapter yourObjects       clickAdapter setOnEntryClickListener new ExampleClickAdapter OnEntryClickListener              Override         public void onEntryClick View view  int position                   stuff that will happen when a list item is clicked                     It s basically how you would set up a normal Adapter  except that you use your setter method that you created to control what you will do when your user clicks a particular list item   You can also look through a set of examples I made on this Gist on GitHub   https   gist github com FarbodSalamat-Zadeh 7646564f48ee708c1582c013e1de4f07

Here is a strategy that gives a result similar to the ListView implementation in that you can define the listener in the Activity or Fragment level instead of the Adapter or ViewHolder level  It also defines some abstract classes that take care of a lot of the boilerplate work of adapters and holders   Abstract Classes  First  define an abstract Holder that extends RecyclerView ViewHolder and defines a generic data type  T  used to bind data to the views  The bindViews method will be implemented by a subclass to map data to the views   public abstract class Holder lt T gt  extends RecyclerView ViewHolder       T data       public Holder View itemView            super itemView              public void bindData T data           this data   data          bindViews data              abstract protected void bindViews T data       Also  create an abstract Adapter that extends RecyclerView Adapter lt Holder lt T gt  gt    This defines 2 of the 3 interface methods  and a subclass will need to implement the last  onViewHolderCreated method   public abstract class Adapter lt T gt  extends RecyclerView Adapter lt Holder lt T gt  gt        List lt T gt  list   new ArrayList lt  gt           Override     public void onBindViewHolder Holder lt T gt  holder  int position            holder bindData list get position                Override     public int getItemCount             return list size               public T getItem int adapterPosition           return list get adapterPosition               Concrete Classes  Now create a new concrete class that extends Holder  This method only has to define the Views and handle the binding  Here I m using the ButterKnife library  but feel free to use itemView findViewById      methods instead   public class PersonHolder extends Holder lt Person gt        Bind R id firstname  TextView firstname       Bind R id lastname  TextView lastname       public PersonHolder View view           super view           ButterKnife bind this  view               Override     protected void bindViews Person person            firstname setText person firstname           lastname setText person lastname             Finally  in your Activity or Fragment class that holds the RecyclerView you would have this code      Create adapter  this happens in parent Activity or Fragment of RecyclerView adapter   new Adapter lt Person gt          Override     public PersonHolder onCreateViewHolder ViewGroup parent  int viewType            View v   LayoutInflater from parent getContext                         inflate R layout layout person view  parent  false            PersonHolder holder   new PersonHolder v           v setOnClickListener new OnClickListener                 Override             public void onClick View v                    int itemPos   holder getAdapterPosition                    Person person   getItem itemPos                       do something with person                 EventBus getDefault   postSticky new PersonClickedEvent itemPos  person                                       return holder

All the answers posted so far are great solutions  however if you do not want to deal with too many implementation details  and just want it to work similarly to how ListView does  I would recommend using TwoWay-View  as seen here   https   github com lucasr twoway-view  Note that this implementation also supports long press on items  as well as support for pressed states  which is something important that other solutions to this question lack    If you don t want to use the entire library  take a look at the ClickItemTouchListener class  which can be used as a standalone if needed  The only issue I found with it at the moment is with long press   scrolling  it seems to have incorrect behaviour

Unfortunately RecyclerView is missing a couple of features that ListView had built-in      For example the ability to add an OnItemClickListener that triggers when an item is clicked       RecyclerView allows you to set an OnClickListener in your adapter  but passing on that click     listener from your calling code  to the adapter and to the ViewHolder  is complicated     for catching a simple item click   public class ItemClickSupport   private final RecyclerView mRecyclerView  private OnItemClickListener mOnItemClickListener  private OnItemLongClickListener mOnItemLongClickListener  private View OnClickListener mOnClickListener   new View OnClickListener          Override     public void onClick View v            if  mOnItemClickListener    null                RecyclerView ViewHolder holder   mRecyclerView getChildViewHolder v               mOnItemClickListener onItemClicked mRecyclerView  holder getAdapterPosition    v                      private View OnLongClickListener mOnLongClickListener   new View OnLongClickListener          Override     public boolean onLongClick View v            if  mOnItemLongClickListener    null                RecyclerView ViewHolder holder   mRecyclerView getChildViewHolder v               return mOnItemLongClickListener onItemLongClicked mRecyclerView  holder getAdapterPosition    v                     return false           private RecyclerView OnChildAttachStateChangeListener mAttachListener           new RecyclerView OnChildAttachStateChangeListener          Override     public void onChildViewAttachedToWindow View view            if  mOnItemClickListener    null                view setOnClickListener mOnClickListener                     if  mOnItemLongClickListener    null                view setOnLongClickListener mOnLongClickListener                         Override     public void onChildViewDetachedFromWindow View view               private ItemClickSupport RecyclerView recyclerView        mRecyclerView   recyclerView      mRecyclerView setTag R id item click support  this       mRecyclerView addOnChildAttachStateChangeListener mAttachListener      public static ItemClickSupport addTo RecyclerView view        ItemClickSupport support    ItemClickSupport  view getTag R id item click support       if  support    null            support   new ItemClickSupport view             return support     public static ItemClickSupport removeFrom RecyclerView view        ItemClickSupport support    ItemClickSupport  view getTag R id item click support       if  support    null            support detach view             return support     public ItemClickSupport setOnItemClickListener OnItemClickListener listener        mOnItemClickListener   listener      return this     public ItemClickSupport setOnItemLongClickListener OnItemLongClickListener listener        mOnItemLongClickListener   listener      return this     private void detach RecyclerView view        view removeOnChildAttachStateChangeListener mAttachListener       view setTag R id item click support  null      public interface OnItemClickListener        void onItemClicked RecyclerView recyclerView  int position  View v      public interface OnItemLongClickListener        boolean onItemLongClicked RecyclerView recyclerView  int position  View v         You also need to define R id item click support using ids xml     lt  xml version  1 0  encoding  utf-8   gt    lt resources gt     lt item name  item click support  type  id    gt    lt  resources gt    The resulting code click listener now looks like this   ItemClickSupport addTo mRecyclerView  setOnItemClickListener new ItemClickSupport OnItemClickListener      Override public void onItemClicked RecyclerView recyclerView  int position  View v           do it         For Brief Explanation about recyclerview clicks please have a look at this littlerobots blog

We can do this using Java weak references  Semantically  the view holder is the one that should respond to the click event or delegate it to the correct responder   Our goals    The Viewholder should know nothing about the the class thats responding to the events except that it implements a certain interface  The click handler should get the position in the RecyclerView of the view thats clicked  We should be able to discern which view was clicked in the view holder  Maintain loose coupling between all components and don t cause any retain cycles    Steps     Create an interface to handle click responses  Implement this interface in the Activity that will handle the click  Add a member variable in the RecyclerView Adapter to hold the Weak Reference and a constructor that sets it  Do the same in the RecyclerView ViewHolder and add a member variable to keep track of position  Set your on click listeners on any view you d like in the ViewHolder  then callback to the responder to handle them  Change your onBindViewHolder method to set the position when binding  Pass the responder down to the ViewHolder  In the responder  you can now use getId   on the view to figure out which view was clicked    And here s a Gist so you can see how it all fits together  RecyclerView click handling

Let s see how we can also implement this with Jetpack   AndroidX  You need to create an observable in the viewmodel class like this  private MutableLiveData lt Integer gt  adapterItem   new MutableLiveData lt  gt      public MutableLiveData lt Integer gt  getAdapterItem         return adapterItem     public void setAdapterItem int adapterItem        this getAdapterItem   setValue adapterItem       Then in the adapter class make sure you pass the viewmodel reference as parameter in the constructor then implement the clicklistener on the viewholder      public MyViewHolder  NonNull View itemView            super itemView           if itemView    null               itemView setOnClickListener v - gt                    int adapterPosition   getAdapterPosition                    viewModel setAdapterItem adapterPosition                                       Then from the activity class just observe the changes      viewModel getAdapterItem   observe this  position - gt            Log w TAG   clicked      ridesArray get position

Usually you have more than one element in your CardView  so that you need an layout view to wrap and organize them  You can add an OnClickListener to that layout view   1  Add an id to your layout  In this case a LinearLayout   lt android support v7 widget CardView        gt        lt LinearLayout         android orientation  vertical          android layout width  match parent          android layout height  match parent          android id    id card view linearLayout  gt            lt TextView             android layout width  wrap content              android layout height  wrap content              android text  name              android id    id card view name    gt                     lt  LinearLayout gt    lt  android support v7 widget CardView gt      2  Get the layout view in your inner ViewHolder class   public static class ViewHolder extends RecyclerView ViewHolder      private TextView nameView              private LinearLayout linearLayout      public ViewHolder View itemView            super itemView           nameView    TextView itemView findViewById R id card view name                       linearLayout    LinearLayout itemView findViewById R id card view linearLayout               3  Add the listener to your layout in onBindViewHolder and use a callback to send data to the Activity or Fragment not tested     Override public void onBindViewHolder TrackAdapter ViewHolder holder  final int position        String str   mStringList get position        holder nameView setText str               holder linearLayout setOnClickListener new View OnClickListener              Override         public void onClick View v                callback itemCallback mStringList get position                          how to use callbacks is another story

The RecyclerView does not have a OnClickListener and will have to implement it ourselves   I like to add a OnItemClickListener interface in Adapter with an onClick method invoked when you click on the item view from the ViewHolder  Thus the responsibility of managing the click on an item is outside the ViewHolder and Adapter  Will the activity or fragment which will decide what to do  Add an interface to the listener and the listener object    public class ItemsAdapter extends RecyclerView Adapter lt ItemsAdapter ViewHolder gt              private static OnItemClickListener onItemClickListener            public static interface OnItemClickListener         public void onItemClick View view  int position                  We capture the click of the root view of the item and when the callback is triggered onClick listener call on the adapter    public class ItemsAdapter extends RecyclerView Adapter lt ItemsAdapter ViewHolder gt              private static OnItemClickListener onItemClickListener            public static interface OnItemClickListener         public void onItemClick View view  int position                 public static class ViewHolder extends RecyclerView ViewHolder         public ImageView imageView         public ViewHolder View itemRootView              super itemRootView             imageView    ImageView  itemRootView findViewById R id itemImage              itemRootView setOnClickListener new View OnClickListener                    Override               public void onClick View view                      int position    ViewHolder super getAdapterPosition                      onItemClickListener onItemClick view position                                                 Since the activity or fragment   fragment in our case   we assign a listener to the adapter and the onClick callback we will get the selected item by position and opened a detailed activity of item   public class ItemsFragment extends Fragment                Override     public View onCreateView LayoutInflater inflater  ViewGroup container                               Bundle savedInstanceState                             ItemsAdapter  adapter  setOnItemClickListener new ItemsAdapter OnItemClickListener                  Override             public void onItemClick View view  int position                      Do something when an item has been clicked

From most of the answers above  they seem to be setting their onclicklisteners to individual items  However  the solution am about to offer is very simple but yet not intuitive to many  Many are forgetting that the other components are always in a parent component which is used to display items in the List or Recycler views  This solution is just about setting a single onclick listener to this parent view and the turn is played  The solution also includes a way to pass the position of the item being clicked on from the list or recycler view  Here  our main rootview is a CardView from the android support library  Here is sample code  public class ListAdapter extends RecyclerView Adapter lt ListAdapter ViewHolder gt     public static final String LOG TAG   ListAdapter class getSimpleName    private Cursor mDataset  private Context mContext  private ViewHolder mViewHolder      Provide a suitable constructor  depends on the kind of dataset  public ListAdapter Context context  Cursor Dataset        mDataset   Dataset      mContext   context        Create new views  invoked by the layout manager   Override public ViewHolder onCreateViewHolder ViewGroup parent  int viewType            create a new view     View v   LayoutInflater from parent getContext                 inflate R layout list business view  parent  false        mViewHolder   new ViewHolder v       return mViewHolder     public void setData Cursor newdata        this mDataset   newdata        Replace the contents of a view  invoked by the layout manager   Override public void onBindViewHolder ViewHolder holder  int position      Bind data to other items here  To save time  i have ommited that               here is where we attach a click listerner for an item in the recycler list rather than for each element of a given item              holder card setOnClickListener new View OnClickListener                      Override                 public void onClick View v                        Toast makeText mContext    Just cliked item at position     itemPosition  Toast LENGTH LONG  show                                            Return the size of your dataset  invoked by the layout manager   Override public int getItemCount         if  null    mDataset            return mDataset getCount              return 0          Provide a reference to the views for each data item    Complex data items may need more than one view per item  and    you provide access to all the views for a data item in a view holder public static class ViewHolder extends RecyclerView ViewHolder         each data item is just a string in this case     public final TextView mBusinesssName     View for the business name     public final TextView mBusinessCategory    View for the category name     public final ImageView businessImage     View for the business category image Image     public final TextView mBusinessDistance     View for the distance     public final CardView card       public ViewHolder View view            super view           mBusinesssName    TextView  view findViewById R id list item name textview           mBusinessCategory    TextView  view findViewById R id list item category textview           mBusinessDistance    TextView  view findViewById R id list item dist textview           businessImage    ImageView  view findViewById R id list item icon           card    CardView  view findViewById R id card view

As the API s have radically changed  It wouldn t surprise me if you were to create an OnClickListener for each item  It isn t that much of a hassle though  In your implementation of RecyclerView Adapter lt MyViewHolder gt   you should have    private final OnClickListener mOnClickListener   new MyOnClickListener      Override public MyViewHolder onCreateViewHolder final ViewGroup parent  final int viewType        View view   LayoutInflater from mContext  inflate R layout myview  parent  false       view setOnClickListener mOnClickListener       return new MyViewHolder view       The onClick method    Override public void onClick final View view        int itemPosition   mRecyclerView getChildLayoutPosition view       String item   mList get itemPosition       Toast makeText mContext  item  Toast LENGTH LONG  show

Way too simple and effective   Instead of implementing interface View OnClickListener inside view holder or creating and interface and implementing interface in your activity - I used this code for simple on OnClickListener implementation   public static class SimpleStringRecyclerViewAdapter             extends RecyclerView Adapter lt SimpleStringRecyclerViewAdapter ViewHolder gt                Your initializations goes here            private List lt String gt  mValues           public static class ViewHolder extends RecyclerView ViewHolder                  create a variable mView             public final View mView                 All your row widgets goes here             public final ImageView mImageView              public final TextView mTextView                 public ViewHolder View view                    super view                     Initialize it here                 mView   view                      your row widgets initializations goes here                 mImageView    ImageView  view findViewById R id avatar                   mTextView    TextView  view findViewById android R id text1                                      public String getValueAt int position                return mValues get position                      public SimpleStringRecyclerViewAdapter Context context  List lt String gt  items                 mBackground   mTypedValue resourceId              mValues   items                      Override         public ViewHolder onCreateViewHolder ViewGroup parent  int viewType                View view   LayoutInflater from parent getContext                         inflate R layout list item  parent  false               view setBackgroundResource mBackground               return new ViewHolder view                       Override         public void onBindViewHolder final ViewHolder holder  int position                holder mBoundString   mValues get position               holder mTextView setText mValues get position                   Here it is simply write onItemClick listener here             holder mView setOnClickListener new View OnClickListener                      Override                 public void onClick View v                        Context context   v getContext                        Intent intent   new Intent context  ExampleActivity class                        context startActivity intent                                                         Override         public int getItemCount                 return mValues size

For me  this is the best way   class YourRecyclerAdapter extends RecyclerView Adapter lt ContactViewHolder gt  implements View OnClickListener             Override   public void onClick View view            int itemPosition   vRecycle getChildPosition view             And use itemPosition to get the item from your collection  This way you dont restrain the ViewHolder with a OnClick callback

I have nice solution for RecyclerView s onItemClickListener for the items and subitems Step 1- Create an interface public interface OnRecyclerViewItemClickListener                  Called when any item with in recyclerview or any item with in item        clicked                 param position                   The position of the item         param id                   The id of the view which is clicked with in the item or                   -1 if the item itself clicked             public void onRecyclerViewItemClicked int position  int id      Step 2- Then use it in adapter s onBindViewHolder method in the following way            Custom created method for Setting the item click listener for the items and items with in items         param listener OnRecyclerViewItemClickListener              public void setOnItemClickListener OnRecyclerViewItemClickListener listener                this listener   listener              Override     public void

    class to hold a reference to each item of RecyclerView     public static class ViewHolder extends RecyclerView ViewHolder                    public TextView albumName  artistName          public

3- find and setup recycler view in activity or fragment where you are using this recyclerView    RecyclerView  rootview findViewById R id vmtopsongs            lm   new LinearLayoutManager mActivity           lm setOrientation LinearLayoutManager VERTICAL           recyclerView setLayoutManager lm           recyclerView addItemDecoration                  new HorizontalDividerItemDecoration Builder getActivity                             paint Utils getPaint    build             PopularSongsadapter mAdapter   new PopularSongsadapter gallery                  mActivity  true              set adapter         recyclerView setAdapter mAdapter           mAdapter setOnItemClickListener this              set item animator to DefaultAnimator         recyclerView setItemAnimator new DefaultItemAnimator      Step 4- Finally implement interface in activity or fragment where you are using the recyclerview  Override     public void onRecyclerViewItemClicked int position  int id                if id  -1               Toast makeText mActivity   quot complete item clicked quot   Toast LENGTH LONG  show             else              Toast makeText mActivity   quot setting button clicked quot   Toast LENGTH LONG  show                     Update for Kotlin Language I have updated the code for kotlin in which only whole view has on click listener   You can set subitems click listener by editing interface and code according to above java code  Adapter class RecentPostsAdapter private val list  MutableList lt Post gt         RecyclerView Adapter lt RecentPostsAdapter

Here is what I did  This solution supports both onClick and onLongClick on both RecyclerView Items and Views insides RecyclerView Items  internal views    I tag viewHolder on the views of my choice    public RecyclerViewAdapter ViewHolder onCreateViewHolder ViewGroup parent  int viewType        View itemView   LayoutInflater from parent getContext    inflate R layout layout item  null       ViewHolder viewHolder   new ViewHolder itemView        itemView setOnClickListener  this       itemView setOnLongClickListener this       viewHolder imageIV setOnClickListener this       viewHolder imageIV setOnLongClickListener this        viewHolder imageIV setTag viewHolder       itemView setTag viewHolder        return viewHolder      And I use holder getPosition   to retrieve the position in onClick   method   onLongClick is similar     public void onClick View view        ViewHolder holder    ViewHolder  view getTag        int position   holder getPosition         if  view getId      holder imageIV getId             Toast makeText context   imageIV onClick at    position  Toast LENGTH SHORT  show          else           Toast makeText context   RecyclerView Item onClick at     position  Toast LENGTH SHORT  show              A variant with getChildPosition also works  Please note that for the internal views  in onClick   use     int position   recyclerView getChildPosition  View view getParent       To my mind  the avantage of this solution is that when one clicks on the image  only the onclick   image listener is called whereas when I combined Jacob s  solution for a RecyclerView Item view and  my solution for internal views the  RecyclerView Item view onclick   is also called  when click on image

In kotlin with constructor implementation  Initialize your Recyclerview constructor like below  class ListAdapter  c  Context  private var list  List lt Project gt   private val itemClick   Project  - gt  Unit     RecyclerView Adapter lt ListAdapter ViewHolder gt       return with itemClick in your onCreateViewHolder  override fun onCreateViewHolder parent  ViewGroup  viewType  Int  ProjectViewHolder       val view   inflater inflate R layout list item  parent  false      return ViewHolder view  itemClick      Your onBindViewHolder  override fun onBindViewHolder holder  ViewHolder  position  Int        holder bindProject list position       Then with viewHolder class create bindProject function   class ViewHolder      view  View      private val itemClick   Project  - gt  Unit     RecyclerView ViewHolder view         private val clientTextCount   7      val titleTextView  TextView   view projectTitleTextView      fun bindProject project  Project            with project                titleTextView text   name             itemView setOnClickListener   itemClick this                        Finally in your activity initialize adapter with lazy   private val adapter  ListAdapter by lazy       ListAdapter this  projectList               Here you can implement your onClick function             For adding new list to recyclerview initialize below method in your adapter  fun setProjects projects  List lt Project gt             projectList   projects         notifyDataSetChanged           and call setProjects method anywhere in your activity   adapter setProjects projects    That s it

Don t reinvent the wheel  The code for this specific use case is included in the Master Detail Flow starter project that comes with Android Studio  From Android Studio select   File  gt  New  gt  New Project     In the Phone and Tablet tab select Master Detail Flow as shown below     Create the project as either Kotlin or Java  Profit   I am not going to include here the code from google s ootb the demo project  but I ll outline the main design approaches in the sample provided by google   the item OnClickListener is created ONLY ONCE  and is assigned to a field in your RecyclerView Adapter implementation  in the onBindViewHolder   you should set the same  pre-created onClickListener object on your ViewHolder instance with holder itemView setOnClickListener mOnClickListener   AVOID creating a new instance on every method call    if you need to capture clicks on some specific elements inside the ViewHolder then extend ViewHolder and expose the elements you need as fields so that you can attach whatever listeners you need in onBindViewHolder       and once again  do NOT re-create the listeners on every method call     initialise them as instance fields and attach them as needed  you can use  setTag   in order to pass state to your viewHolder  e g  holder itemView setTag mValues get position    as used in the demo

If you want to catch click event On Individual items then just implement OnClickListener in ViewHolder class and then set click listeners on individual views or whole itemView   Following example shows the same  public  class ContactViewHolder extends RecyclerView ViewHolder implements OnClickListener               TextView txt title txt name txt email           public ContactViewHolder View itemView                         super itemView               txt title    TextView itemView findViewById R id txt title               txt name     TextView itemView findViewById R id txt name               txt email    TextView itemView findViewById R id txt email                txt name setOnClickListener this               txt email setOnClickListener this               itemView setOnClickListener this                       Override         public void onClick View v                   TODO Auto-generated method stub              if v    itemView                                Toast makeText RecyclerDemoActivity this   Visiting Card Clicked is    gt   txt name getText    Toast LENGTH SHORT  show                               if v    txt name                                Toast makeText RecyclerDemoActivity this   Name    gt   txt name getText    Toast LENGTH SHORT  show                               if v    txt email                                Toast makeText RecyclerDemoActivity this   Email    gt   txt email getText    Toast LENGTH SHORT  show

Check out a similar question  CommonsWare s comment links to this  which implements the OnClickListener interface in the viewHolder   Here s a simple example of the ViewHolder       TextView textView   declare global with in adapter class  public static class ViewHolder extends RecyclerView ViewHolder implements View OnClickListener          private ViewHolder View itemView                super itemView               itemView setOnClickListener this               textView    TextView view findViewById android R id text1                    Override       public void onClick View view                Toast makeText view getContext     position       getLayoutPosition    Toast LENGTH SHORT  show                go through each item if you have few items within recycler view         if getLayoutPosition    0                Do whatever you want here           else if getLayoutPosition    1                 Do whatever you want here                    else if getLayoutPosition    2             else if getLayoutPosition    3             else if getLayoutPosition    4             else if getLayoutPosition    5                         or you can use For loop if you have long list of items  Use its length or size of the list as          for int i   0  i lt exampleList size    i                                The Adapter then looks like this        Override     public ViewHolder onCreateViewHolder ViewGroup parent  int viewType            View view  LayoutInflater from parent getContext    inflate android R layout simple list item 1  parent  false            return new ViewHolder view

According to Yigit Boyar  the best way to register a click on a RecyclerView is to define the click in the creation of the viewholder instead of just creating a new onClickListener for each item that the onBindViewHolder binds Example override fun onCreateViewHolder parent  ViewGroup  viewType  Int   BaseViewHolder lt   gt            val itemBinding   LayoutInflater from context  inflate R layout my layout  parent  false          val vh   MainViewHolder itemBinding           vh itemView setOnClickListener               val pos   vh adapterPosition             if pos    NO POSITION                   itemClickLister onCocktailClick myList pos  pos                              return vh

For me the clean way to do that is this one   Adapter constructor  private class EnvironmentTypeRecyclerViewAdapter extends RecyclerView Adapter lt EnvironmentTypeRecyclerViewAdapter ViewHolder gt         private final EnvironmentTypeRecyclerViewAdapterListener mEnvironmentTypeRecyclerViewAdapterListener       private List lt Environment gt  mEnvironmentsData        public class ViewHolder extends RecyclerView ViewHolder implements View OnClickListener                 public ViewHolder View v                          super v                v setOnClickListener this                          Override          public void onClick View v                           Environment environment   mEnvironmentsData get getAdapterPosition                   if  mEnvironmentTypeRecyclerViewAdapterListener    null  amp  amp  environment    null                          mEnvironmentTypeRecyclerViewAdapterListener onListItemSelected environment                                            public EnvironmentTypeRecyclerViewAdapter List lt SmallCellEnvironment gt  environments  EnvironmentTypeRecyclerViewAdapterListener environmentTypeRecyclerViewAdapterListener                        mEnvironmentTypeRecyclerViewAdapterListener   environmentTypeRecyclerViewAdapterListener              mEnvironmentsData   environments                The Linked Interface   private interface EnvironmentTypeRecyclerViewAdapterListener       void onListItemSelected Environment environment
