Android 5 0 - Add header footer to a RecyclerView

Question

I spent a moment trying to figure out a way to add a header to a RecyclerView  unsuccessfully   This is what I got so far    Override protected void onCreate Bundle savedInstanceState                 layouManager   new LinearLayoutManager getActivity         recyclerView setLayoutManager layouManager        LayoutInflater inflater    LayoutInflater  getActivity   getSystemService Context LAYOUT INFLATER SERVICE       headerPlaceHolder   inflater inflate R layout view header holder medium  null  false       layouManager addView headerPlaceHolder  0               The LayoutManager seems to be the object handling the disposition of the RecyclerView items  As I couldn t find any addHeaderView View view  method  I decided to go with the LayoutManager s addView View view  int position  method and to add my header view in the first position to act as a header    Aaand this is where things get uglier   java lang NullPointerException  Attempt to read from field  android support v7 widget RecyclerView ViewHolder android support v7 widget RecyclerView LayoutParams mViewHolder  on a null object reference     at android support v7 widget RecyclerView getChildViewHolderInt RecyclerView java 2497      at android support v7 widget RecyclerView LayoutManager addViewInt RecyclerView java 4807      at android support v7 widget RecyclerView LayoutManager addView RecyclerView java 4803      at com mathieumaree showz fragments CategoryFragment setRecyclerView CategoryFragment java 231      at com mathieumaree showz fragments CategoryFragment access 200 CategoryFragment java 47      at com mathieumaree showz fragments CategoryFragment 2 success CategoryFragment java 201      at com mathieumaree showz fragments CategoryFragment 2 success CategoryFragment java 196      at retrofit CallbackRunnable 1 run CallbackRunnable java 41      at android os Handler handleCallback Handler java 739      at android os Handler dispatchMessage Handler java 95      at android os Looper loop Looper java 135      at android app ActivityThread main ActivityThread java 5221      at java lang reflect Method invoke Native Method      at java lang reflect Method invoke Method java 372      at com android internal os ZygoteInit MethodAndArgsCaller run ZygoteInit java 899      at com android internal os ZygoteInit main ZygoteInit java 694    After getting several NullPointerExceptions trying to call the addView View view  at different moments of the Activity creation  also tried adding the view once everything is set up  even the Adapter s data   I realized I have no idea if this is the right way to do it  and it doesn t look to be    PS  Also  a solution that could handle the GridLayoutManager in addition to the LinearLayoutManager would be really appreciated

recyclerview 1 2 0 introduces ConcatAdapter class which concatenates multiple adapters into a single one  So it allows to create separate header footer adapters and reuse them across multiple lists  myRecyclerView adapter   ConcatAdapter headerAdapter  listAdapter  footerAdapter   Take a look at the announcement article  It contains a sample how to display a loading progress in header and footer using ConcatAdapter  For the moment when I post this answer the version 1 2 0 of the library is in alpha stage  so the api might change  You can check the status here

You can used this GitHub library allowing to add Header and or Footer in your RecyclerView in the simplest way possible   You need to add HFRecyclerView library in your project or you can also grab it from Gradle   compile  com mikhaellopez hfrecyclerview 1 0 0    This is a result in image     EDIT   If you just want to add a margin at the top and or bottom with this library  SimpleItemDecoration   int offsetPx   10  recyclerView addItemDecoration new StartOffsetItemDecoration offsetPx    recyclerView addItemDecoration new EndOffsetItemDecoration offsetPx

You can use the library SectionedRecyclerViewAdapter to group your items in sections and add a header to each section  like on the image below     First you create your section class   class MySection extends StatelessSection        String title      List lt String gt  list       public MySection String title  List lt String gt  list               call constructor with layout resources for this Section header  footer and items          super R layout section header  R layout section item            this title   title          this list   list              Override     public int getContentItemsTotal             return list size       number of items of this section             Override     public RecyclerView ViewHolder getItemViewHolder View view               return a custom instance of ViewHolder for the items of this section         return new MyItemViewHolder view               Override     public void onBindItemViewHolder RecyclerView ViewHolder holder  int position            MyItemViewHolder itemHolder    MyItemViewHolder  holder              bind your view here         itemHolder tvItem setText list get position                Override     public RecyclerView ViewHolder getHeaderViewHolder View view            return new SimpleHeaderViewHolder view               Override     public void onBindHeaderViewHolder RecyclerView ViewHolder holder            MyHeaderViewHolder headerHolder    MyHeaderViewHolder  holder              bind your header view here         headerHolder tvItem setText title             Then you set up the RecyclerView with your sections and change the SpanSize of the headers with a GridLayoutManager      Create an instance of SectionedRecyclerViewAdapter  SectionedRecyclerViewAdapter sectionAdapter   new SectionedRecyclerViewAdapter        Create your sections with the list of data MySection section1   new MySection  My Section 1 title   dataList1   MySection section2   new MySection  My Section 2 title   dataList2       Add your Sections to the adapter sectionAdapter addSection section1   sectionAdapter addSection section2       Set up a GridLayoutManager to change the SpanSize of the header GridLayoutManager glm   new GridLayoutManager getContext    2   glm setSpanSizeLookup new GridLayoutManager SpanSizeLookup          Override     public int getSpanSize int position            switch sectionAdapter getSectionItemViewType position                 case SectionedRecyclerViewAdapter VIEW TYPE HEADER                  return 2              default                  return 1                          Set up your RecyclerView with the SectionedRecyclerViewAdapter RecyclerView recyclerView    RecyclerView  findViewById R id recyclerview   recyclerView setLayoutManager glm   recyclerView setAdapter sectionAdapter

I had to add a footer to my RecyclerView and here I m sharing my code snippet as I thought it might be useful  Please check the comments inside the code for better understanding of the overall flow   import android content Context  import android support v7 widget RecyclerView  import android view LayoutInflater  import android view View  import android view ViewGroup   import java util ArrayList   public class RecyclerViewWithFooterAdapter extends RecyclerView Adapter lt RecyclerView ViewHolder gt         private static final int FOOTER VIEW   1      private ArrayList lt String gt  data     Take any list that matches your requirement      private Context context          Define a constructor     public RecyclerViewWithFooterAdapter Context context  ArrayList lt String gt  data            this context   context          this data   data                Define a ViewHolder for Footer view     public class FooterViewHolder extends ViewHolder           public FooterViewHolder View itemView                super itemView               itemView setOnClickListener new View OnClickListener                      Override                 public void onClick View v                           Do whatever you want on clicking the item                                                           Now define the ViewHolder for Normal list item     public class NormalViewHolder extends ViewHolder           public NormalViewHolder View itemView                super itemView                itemView setOnClickListener new View OnClickListener                      Override                 public void onClick View v                           Do whatever you want on clicking the normal items                                                           And now in onCreateViewHolder you have to pass the correct view        while populating the list item        Override     public RecyclerView ViewHolder onCreateViewHolder ViewGroup parent  int viewType             View v           if  viewType    FOOTER VIEW                v   LayoutInflater from context  inflate R layout list item footer  parent  false               FooterViewHolder vh   new FooterViewHolder v               return vh                     v   LayoutInflater from context  inflate R layout list item normal  parent  false            NormalViewHolder vh   new NormalViewHolder v            return vh                Now bind the ViewHolder in onBindViewHolder      Override     public void onBindViewHolder RecyclerView ViewHolder holder  int position             try               if  holder instanceof NormalViewHolder                    NormalViewHolder vh    NormalViewHolder  holder                   vh bindView position                 else if  holder instanceof FooterViewHolder                    FooterViewHolder vh    FooterViewHolder  holder                          catch  Exception e                e printStackTrace                            Now the critical part  You have return the exact item count of your list        I ve only one footer  So I returned data size     1        If you ve multiple headers and footers  you ve to return total count        like  headers size     data size     footers size         Override     public int getItemCount             if  data    null                return 0                     if  data size      0                  Return 1 here to show nothing             return 1                        Add extra view to show the footer view         return data size     1                Now define getItemViewType of your own        Override     public int getItemViewType int position            if  position    data size                     This is where we ll add footer              return FOOTER VIEW                     return super getItemViewType position                 So you re done with adding a footer and its action on onClick         Now set the default ViewHolder for NormalViewHolder      public class ViewHolder extends RecyclerView ViewHolder              Define elements of a row here         public ViewHolder View itemView                super itemView                  Find view by ID and initialize here                    public void bindView int position                   bindView   method to implement actions                     The above code snippet adds a footer to the RecyclerView  You can check this GitHub repository for checking the implementation of adding both header and a footer

You can use viewtype to solve this problem  here is my demo  https   github com yefengfreedom RecyclerViewWithHeaderFooterLoadingEmptyViewErrorView   you can define some recycler view display mode   public static final int MODE DATA   0  MODE LOADING   1  MODE ERROR   2  MODE EMPTY   3  MODE HEADER VIEW   4  MODE FOOTER VIEW   5    2 override the getItemViewType mothod    Override public int getItemViewType int position        if  mMode    RecyclerViewMode MODE LOADING            return RecyclerViewMode MODE LOADING            if  mMode    RecyclerViewMode MODE ERROR            return RecyclerViewMode MODE ERROR            if  mMode    RecyclerViewMode MODE EMPTY            return RecyclerViewMode MODE EMPTY              check what type our position is  based on the assumption that the order is headers  gt  items  gt  footers     if  position  lt  mHeaders size              return RecyclerViewMode MODE HEADER VIEW        else if  position  gt   mHeaders size     mData size              return RecyclerViewMode MODE FOOTER VIEW            return RecyclerViewMode MODE DATA      3 override the getItemCount method   Override public int getItemCount         if  mMode    RecyclerViewMode MODE DATA            return mData size     mHeaders size     mFooters size          else           return 1            4 override the onCreateViewHolder method  create view holder by viewType   Override public RecyclerView ViewHolder onCreateViewHolder ViewGroup parent  int viewType        if  viewType    RecyclerViewMode MODE LOADING            RecyclerView ViewHolder loadingViewHolder   onCreateLoadingViewHolder parent           loadingViewHolder itemView setLayoutParams                  new ViewGroup LayoutParams ViewGroup LayoutParams MATCH PARENT  parent getHeight   -

I ended up implementing my own adapter to wrap any other adapter and provide methods to add header and footer views   Created a gist here  HeaderViewRecyclerAdapter java  The main feature I wanted was a similar interface to a ListView  so I wanted to be able to inflate the views in my Fragment and add them to the RecyclerView in onCreateView  This is done by creating a HeaderViewRecyclerAdapter passing the adapter to be wrapped  and calling addHeaderView and addFooterView passing your inflated views  Then set the HeaderViewRecyclerAdapter instance as the adapter on the RecyclerView   An extra requirement was that I needed to be able to easily swap out adapters while keeping the headers and footers  I didn t want to have multiple adapters with multiple instances of these headers and footers  So you can call setAdapter to change the wrapped adapter leaving the headers and footers intact  with the RecyclerView being notified of the change

Based on  seb s solution  I created a subclass of RecyclerView Adapter that supports an arbitrary number of headers and footers   https   gist github com mheras 0908873267def75dc746  Although it seems to be a solution  I also think this thing should be managed by the LayoutManager  Unfortunately  I need it now and I don t have time to implement a StaggeredGridLayoutManager from scratch  nor even extend from it    I m still testing it  but you can try it out if you want  Please let me know if you find any issues with it

I know I come late  but only recently I was able to implement such  addHeader  to the Adapter  In my FlexibleAdapter project you can call setHeader on a Sectionable item  then you call showAllHeaders  If you need only 1 header then the first item should have the header  If you delete this item  then the header is automatically linked to the next one   Unfortunately footers are not covered  yet    The FlexibleAdapter allows you to do much more than create headers sections  You really should have a look  https   github com davideas FlexibleAdapter

Very simple to solve    I don t like an idea of having logic inside adapter as a different view type because every time it checks for the view type before returning the view  Below solution avoids extra checks   Just add LinearLayout  vertical  header view   recyclerview   footer view inside android support v4 widget NestedScrollView    Check this out     lt android support v4 widget NestedScrollView     android layout width  match parent      android layout height  match parent  gt        lt LinearLayout         android layout width  match parent          android layout height  match parent          android orientation  vertical  gt           lt View             android id    id header              android layout width  match parent              android layout height  wrap content   gt            lt android support v7 widget RecyclerView             android id    id list              android layout width  match parent              android layout height  wrap content              app layoutManager  LinearLayoutManager   gt            lt View             android id    id footer              android layout width  match parent              android layout height  wrap content   gt       lt  LinearLayout gt   lt  android support v4 widget NestedScrollView gt    Add this line of code for smooth scrolling  RecyclerView v    RecyclerView  findViewById       v setNestedScrollingEnabled false     This will lose all RV performance and RV will try to lay out all view holders regardless of the layout height of RV  Recommended using for the small size list like Nav drawer or settings etc

I had the same problem on Lollipop and created two approaches to wrap the Recyclerview adapter  One is pretty easy to use  but I m not sure how it will behave with a changing dataset  Because it wraps your adapter and you need to make yourself sure to call methods like notifyDataSetChanged on the right adapter-object   The other shouldn t have such problems  Just let your regular adapter extend the class  implement the abstract methods and you should be ready  And here they are   gists   HeaderRecyclerViewAdapterV1 java usage new HeaderRecyclerViewAdapterV1 new RegularAdapter     HeaderRecyclerViewAdapterV2 java usage RegularAdapter extends HeaderRecyclerViewAdapterV2    HeaderRecyclerViewAdapterV1  import android support v7 widget RecyclerView  import android view ViewGroup          Created by sebnapi on 08 11 14      lt p  gt     This is a Plug-and-Play Approach for adding a Header or Footer to    a RecyclerView backed list     lt p  gt     Just wrap your regular adapter like this     lt p  gt     new HeaderRecyclerViewAdapterV1 new RegularAdapter        lt p  gt     Let RegularAdapter implement HeaderRecyclerView  FooterRecyclerView or both    and you are ready to go      lt p  gt     I m absolutely not sure how this will behave with changes in the dataset     You can always wrap a fresh adapter and make sure to not change the old one or    use my other approach      lt p  gt     With the other approach you need to let your Adapter extend HeaderRecyclerViewAdapterV2     and therefore change potentially more code  but possible omit these shortcomings      lt p  gt     TOTALLY UNTESTED -

 useHeader     1   0  and instead created a public method int offsetPosition int position  for it  Because if you set an OnItemTouchListener on Recyclerview  you can intercept the touch  get the x y coordinates of the touch  find the according child view and then call recyclerView getChildPosition     and you will always get the non-offsetted position in the adapter  This is a shortcomming in the RecyclerView Code  I don t see an easy method to overcome this  This is why I now offset the positions explicit when I need to by my own code

I haven t tried this  but I would simply add 1  or 2  if you want both a header and footer  to the integer returned by getItemCount in your adapter  You can then override getItemViewType in your adapter to return a different integer when i  0  https   developer android com reference android support v7 widget RecyclerView Adapter html getItemViewType int   createViewHolder is then passed the integer you returned from getItemViewType  allowing you to create or configure the view holder differently for the header view  https   developer android com reference android support v7 widget RecyclerView Adapter html createViewHolder android view ViewGroup  int   Don t forget to subtract one from the position integer passed to bindViewHolder

I would just add an alternative to all those HeaderRecyclerViewAdapter implementation  CompoundAdapter   https   github com negusoft CompoundAdapter-android  It is a more flexible approach  since you can create a AdapterGroup out of Adapters  For the header example  use your adapter as it is  along with an adapter containing one item for the header   AdapterGroup adapterGroup   new AdapterGroup    adapterGroup addAdapter SingleAdapter create R layout header    adapterGroup addAdapter new MyAdapter         recyclerView setAdapter adapterGroup     It is fairly simple and readable  You can implement more complex adapter easily using the same principle
