I want to catch an event when the user finishes editing EditText   How can it be done

User · Answer

I have done something like this abstract class that can be used in place of TextView OnEditorActionListener type    abstract class OnTextEndEditingListener   TextView OnEditorActionListener        override fun onEditorAction textView  TextView   actionId  Int  event  KeyEvent    Boolean            if actionId    EditorInfo IME ACTION SEARCH                    actionId    EditorInfo IME ACTION DONE                    actionId    EditorInfo IME ACTION NEXT                    event    null  amp  amp                  event action    KeyEvent ACTION DOWN  amp  amp                  event keyCode    KeyEvent KEYCODE ENTER                 if event    null     event isShiftPressed                       the user is done typing                  return onTextEndEditing textView  actionId  event                                  return false    pass on to other listeners            abstract fun onTextEndEditing textView  TextView   actionId  Int  event  KeyEvent     Boolean

Although many answers do point in the right direction I think none of them answers what the author of the question was thinking about  Or at least I understood the question differently because I was looking for answer to similar problem   The problem is  How to know when the user stops typing without him pressing a button  and trigger some action  for example auto-complete   If you want to do this start the Timer in  onTextChanged with a delay that you would consider user stopped typing  for example 500-700ms   for each new letter when you start the timer cancel the earlier one  or at least use some sort of flag that when they tick they don t do anything   Here is similar code to what I have used   new Timer   schedule new TimerTask        Override   public void run          if   running                                        new DoPost   execute s toString                 700     Note that I modify running boolean flag inside my async task  Task gets the json from the server for auto-complete    Also keep in mind that this creates many timer tasks  I think they are scheduled on the same Thread thou but would have to check this   so there are probably many places to improve but this approach also works and the bottom line is that you should use a Timer since there is no  User stopped typing event

I had the same problem when trying to implement  now typing  on chat app  try to extend EditText as follows   public class TypingEditText extends EditText implements TextWatcher    private static final int TypingInterval   2000    public interface OnTypingChanged       public void onTyping EditText view  boolean isTyping     private OnTypingChanged t  private Handler handler        handler   new Handler      public TypingEditText Context context  AttributeSet attrs  int defStyleAttr        super context  attrs  defStyleAttr       this addTextChangedListener this      public TypingEditText Context context  AttributeSet attrs        super context  attrs       this addTextChangedListener this      public TypingEditText Context context        super context       this addTextChangedListener this      public void setOnTypingChanged OnTypingChanged t        this t   t      Override public void afterTextChanged Editable s        if t    null           t onTyping this  true           handler removeCallbacks notifier           handler postDelayed notifier  TypingInterval             private Runnable notifier   new Runnable           Override     public void run             if t    null              t onTyping TypingEditText this  false              Override public void beforeTextChanged CharSequence s  int start  int count  int after         Override public void onTextChanged CharSequence text  int start  int lengthBefore  int lengthAfter

Simple to trigger finish typing in EditText  worked for me   if you using java convert it   In Kotlin  youredittext doAfterTextChanged   searchTerm - gt  val currentTextLength   searchTerm  length     Handler   postDelayed           if  currentTextLength    searchTerm  length                   your code             Log d  aftertextchange    ON FINISH TRIGGER                         3000

A different approach      here is an example   If the user has a delay of 600-1000ms when is typing you may consider he s stopped    x000D   x000D   myEditText addTextChangedListener new TextWatcher     x000D                x000D              private String s  x000D              private long after  x000D     private Thread t  x000D              private Runnable runnable EditTextWatcher   new Runnable     x000D                   Override x000D                  public void run     x000D                      while  true    x000D                          if   System currentTimeMillis   - after   gt  600  x000D                            x000D                              Log d  Debug EditTEXT watcher     System currentTimeMillis  -after  gt 600 - gt        System currentTimeMillis   - after       gt      s   x000D                                 Do your stuff x000D                              t   null  x000D                              break  x000D                            x000D                        x000D                    x000D                 x000D               x000D               Override x000D              public void onTextChanged CharSequence ss  int start  int before  int count    x000D                  s   ss toString    x000D                x000D               x000D               Override x000D              public void beforeTextChanged CharSequence s  int start  int count  int after    x000D                x000D               x000D               Override x000D              public void afterTextChanged Editable ss    x000D                  after   System currentTimeMillis    x000D                  if  t    null  x000D                    x000D                      t   new Thread runnable EditTextWatcher   x000D                        t start    x000D                    x000D                x000D              x000D   x000D   x000D

I solved this problem this way  I used kotlin           var timer   Timer           var DELAY Long   2000          editText addTextChangedListener object   TextWatcher                override fun afterTextChanged s  Editable                     Log e  TAG   timer start                   timer   Timer                   timer schedule object   TimerTask                         override fun run                               do something                                          DELAY                             override fun beforeTextChanged s  CharSequence   start  Int  count  Int  after  Int                  override fun onTextChanged s  CharSequence   start  Int  before  Int  count  Int                    Log e  TAG   timer cancel                    timer cancel     Terminates this timer discarding any currently scheduled tasks                  timer purge     Removes all cancelled tasks from this timer s task queue

I personally prefer automatic submit after end of typing  Here s how you can detect this event   Declarations and initialization   private Timer timer   new Timer    private final long DELAY   1000     in ms   Listener in e g  onCreate    EditText editTextStop    EditText  findViewById R id editTextStopId       editTextStop addTextChangedListener new TextWatcher              Override         public void beforeTextChanged CharSequence s  int start  int count                  int after                       Override         public void onTextChanged final CharSequence s  int start  int before                  int count                if timer    null                  timer cancel                       Override         public void afterTextChanged final Editable s                  avoid triggering event when text is too short             if  s length    gt   3                                   timer   new Timer                    timer schedule new TimerTask                          Override                     public void run                                TODO  do what you need here  refresh list                             you will probably need to use                            runOnUiThread Runnable action  for some specific                            actions                         serviceConnector getStopPoints s toString                                               DELAY                                     So  when text is changed the timer is starting to wait for any next changes to happen  When they occure timer is cancelled and then started once again

I had the same issue and did not want to rely on the user pressing Done or Enter    My first attempt was to use the onFocusChange listener  but it occurred that my EditText got the focus by default  When user pressed some other view  the onFocusChange was triggered without the user ever having assigned it the focus   Next solution did it for me  where the onFocusChange is attached if the user touched the EditText   final myEditText   new EditText myContext     make final to refer in onTouch myEditText setOnTouchListener new OnTouchListener               Override         public boolean onTouch View v  MotionEvent event                myEditText setOnFocusChangeListener new OnFocusChangeListener                       Override                 public void onFocusChange View v  boolean hasFocus                        if  hasFocus                              user is done editing                                                                     In my case  when the user was done editing the screen was rerendered  thereby renewing the myEditText object  If the same object is kept  you should probably remove the onFocusChange listener in onFocusChange to prevent the onFocusChange issue described at the start of this post

Better way  you can also use EditText onFocusChange listener to check whether user has done editing   Need not rely on user pressing the Done or Enter button on Soft keyboard      EditText findViewById R id youredittext   setOnFocusChangeListener new OnFocusChangeListener           Override     public void onFocusChange View v  boolean hasFocus              When focus is lost check that the text field has valid values         if   hasFocus                  Validate youredittext                      Note   For more than one EditText  you can also let your class implement View OnFocusChangeListener then set the listeners to each of you EditText and validate them as below    EditText findViewById R id edittext1   setOnFocusChangeListener this     EditText findViewById R id edittext2   setOnFocusChangeListener this         Override     public void onFocusChange View v  boolean hasFocus              When focus is lost check that the text field has valid values         if   hasFocus            switch  view getId                 case R id edittext1                      Validate EditText1                  break             case R id edittext2                      Validate EditText2                  break

You can do it using setOnKeyListener or using a textWatcher like   Set text watcher editText addTextChangedListener textWatcher    then call  private TextWatcher textWatcher   new TextWatcher               Override         public void onTextChanged CharSequence s  int start  int before  int count                  after text changed                     Override         public void beforeTextChanged CharSequence s  int start  int count                  int after                        Override         public void afterTextChanged Editable s

I ended her with the same problem and I could not use the the solution with onEditorAction or onFocusChange and did not want to try the timer  A timer is too dangerous for may taste  because of all the threads and too unpredictable  as you do not know when you code is executed   The onEditorAction do not catch when the user leave without using a button and if you use it please notice that KeyEvent can be null  The focus is unreliable at both ends the user can get focus and leave without enter any text or selecting the field and the user do not need to leave the last EditText field   My solution use  onFocusChange and a flag set when the user starts editing text and a function to get the text from the last focused view  which I call when need   I just clear the focus on all my text fields to tricker the leave text view code  The clearFocus code is only executed if the field has focus  I call the function in onSaveInstanceState so I do not have to save the flag  mEditing  as a state of the EditText view and when important buttons is clicked and when the activity is closed    Be careful with TexWatcher as it is call often I use the condition on focus to not react when the onRestoreInstanceState code entering text  I   final EditText mEditTextView    EditText  getView         mEditTextView addTextChangedListener new TextWatcher              Override         public void beforeTextChanged CharSequence s  int start  int count  int after                         Override         public void onTextChanged CharSequence s  int start  int before  int count                         Override         public void afterTextChanged Editable s                if   mEditing  amp  amp  mEditTextView hasFocus                      mEditing   true                                      mEditTextView setOnFocusChangeListener new View OnFocusChangeListener               Override         public void onFocusChange View v  boolean hasFocus                if   hasFocus  amp  amp  mEditing                    mEditing   false                     Do the thing                                 protected void saveLastOpenField        for  EditText view getFields                 view clearFocus

Okay this will work 100  for sure   First you will need to setup listener if keyboard is show or hide  If keyboard is showing then probably user is typing  otherwise done typing   final View activityRootView   findViewById android R id content           activityRootView getViewTreeObserver   addOnGlobalLayoutListener new ViewTreeObserver OnGlobalLayoutListener                  Override             public void onGlobalLayout                          Rect r   new Rect                          r will be populated with the coordinates of your view that area still visible                      activityRootView getWindowVisibleDisplayFrame r                        int heightDiff   activityRootView getRootView   getHeight   -  r bottom - r top                       if  heightDiff  gt  100       if more than 100 pixels  its probably a keyboard                             isTyping   true                        else     to make sure this will call only once when keyboard is hide                          if isTyping                               isTyping   false
