Soft keyboard open and close listener in an activity in Android

Question

I have an Activity where there are 5 EditTexts  When the user clicks on the first EditText  the soft keyboard opens to enter some value in it  I want to set some other View s visibility to Gone when the soft keyboard opens and also when the user clicks on the first EditText and also when the soft keyboard closes from the same EditText on the back button press  Then I want to set some other View s visibility to visible   Is there any listener or callback or any hack for when the soft keyboard opens from a click on the first EditText in Android

There is a keyboard dismissed listener  Class SearchEditText is derived from android widget EditText class  There is an interface SearchEditText OnKeyboardDismissListener in this class  You can look docmentation  https   developer android com reference androidx leanback widget SearchEditText Note  Before use SearchEditText you need to set up Gradle dependencies in the build gradle   app   implementation  androidx leanback leanback 1 1 0-alpha05   Maybe someone will come in handy  Detailed response  import androidx appcompat app AppCompatActivity  import androidx leanback widget SearchEditText   import android os Bundle  import android widget Toast   public class MainActivity extends AppCompatActivity         implements SearchEditText OnKeyboardDismissListener        SearchEditText searchEditText        Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout activity main            searchEditText   findViewById R id search edit text            searchEditText setOnKeyboardDismissListener this                         Method invoked when the keyboard is dismissed               Override     public void onKeyboardDismiss             Toast makeText this   quot The listener worked quot   Toast LENGTH LONG  show             activity main xml  lt  xml version  quot 1 0 quot  encoding  quot utf-8 quot   gt   lt androidx constraintlayout widget ConstraintLayout     xmlns android  quot http   schemas android com apk res android quot      xmlns app  quot http   schemas android com apk res-auto quot      xmlns tools  quot http   schemas android com tools quot      android layout width  quot match parent quot      android layout height  quot match parent quot      tools context  quot  MainActivity quot  gt        lt androidx leanback widget SearchEditText         android id  quot   id search edit text quot          android layout width  quot match parent quot          android layout height  quot wrap content quot          android layout margin  quot 12dp quot          android textSize  quot 20sp quot          android focusableInTouchMode  quot true quot          app layout constraintTop toTopOf  quot parent quot    gt    lt  androidx constraintlayout widget ConstraintLayout gt   Note  listener works with  android windowSoftInputMode  quot adjustPan quot  android windowSoftInputMode  quot adjustResize quot

Unfortunately I do not have a sufficiently high reputation to comment on Jaap van Hengstum s answer  But I read a few comments of people  having the problem that contentViewTop is always 0 and that onShowKeyboard      is always called    I had the same issue and figured out the problem I had  I used an AppCompatActivity instead of a  normal  Activity  In this case Window ID ANDROID CONTENT refers to an ContentFrameLayout and not to the FrameLayout with the right top-value  In my case it was fine to use the  normal  Activity  if you have to use another activity-type  I just tested the AppCompatActivity  maybe it s also an issue with other acitivy-types like the FragmentActivity   you have to access the FrameLayout  which is  an ancestor of the ContentFrameLayout

As Vikram pointed out in the comments  detecting whether the softkeyboard is shown or has disappeared is only possible with some ugly hacks   Maybe it is enough to set a focus listener on the edittext   yourEditText setOnFocusChangeListener new OnFocusChangeListener      Override public void onFocusChange View v  boolean hasFocus            if  hasFocus                  got focus           else                 lost focus

You can handle keyboard visibility by overriding two methods in your Activity  onKeyUp   and onKeyDown   more information in this link  https   developer android com training keyboard-input commands

Solution with extra property in Activity Fragment  but without any hypothetical hardcoded heights  like 100 etc    Just add OnGlobalLayoutListener to your root view and save its initial height before keyboard will be shown  var firstLoad           true var contentFullWeight   0  override fun onViewCreated layoutView  View  savedInstanceState  Bundle         super onViewCreated layoutView  savedInstanceState       view  viewTreeObserver  addOnGlobalLayoutListener ViewTreeObserver OnGlobalLayoutListener            if firstLoad               contentFullWeight   view  height               firstLoad   false                    if  view  height    lt  contentFullWeight                Log d  quot TEZT KEYBOARD quot    quot  gt  gt  KBD OPENED quot             else               Log d  quot TEZT KEYBOARD quot    quot  gt  gt  KBD closed quot

I am late but I just found a very convenient dependency out there  Using it you can check the visibility of the keyboard as well as make the keyboard  quot Hide quot  and Show Whenever you want with a single Line of Code  implementation  net yslibrary keyboardvisibilityevent keyboardvisibilityevent 3 0 0-RC2   And then you simply use this code segment to check the keyboard visibility  KeyboardVisibilityEvent setEventListener this  new KeyboardVisibilityEventListener               Override   public void onVisibilityChanged boolean isOpen     if  isOpen     Toast makeText MainActivity this   quot keyboard opened quot  Toast LENGTH SHORT  show    else    Toast makeText MainActivity this   quot keyboard hidden quot   Toast LENGTH SHORT  show           Then if you want to Hide Show keyboard at any point of time then you can just write one of these single lines to achieve it          UIUtil showKeyboard this edittext to be focused           UIUtil hideKeyboard this

A different approach would be to check when the user stopped typing     When a TextEdit is in focus  user is was typing  you could hide the views  focus listener    and use a Handler   Runnable and a text change listener to close the keyboard  regardless of its visibility  and show the views after some delay   The main thing to look out for would be the delay you use  which would depend on the content of these TextEdits    Handler timeoutHandler   new Handler    Runnable typingRunnable   new Runnable         public void run                current TextEdit         View view   getCurrentFocus             InputMethodManager imm    InputMethodManager  getSystemService Context INPUT METHOD SERVICE              reset focus         view clearFocus               close keyboard  whether its open or not          imm hideSoftInputFromWindow view getWindowToken    InputMethodManager RESULT UNCHANGED SHOWN               SET VIEWS VISIBLE           editText setOnFocusChangeListener new View OnFocusChangeListener          Override     public void onFocusChange View v  boolean hasFocus            if  hasFocus                   SET VIEWS GONE                 reset handler             timeoutHandler removeCallbacks typingRunnable               timeoutHandler postDelayed typingRunnable  TYPING TIMEOUT                        editText 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               Reset Handler            timeoutHandler removeCallbacks typingRunnable               Override     public void afterTextChanged Editable s               Reset Handler Cont          if  editText getText   toString   trim   length    gt  0                timeoutHandler postDelayed typingRunnable  TYPING TIMEOUT

This only works when android windowSoftInputMode of your activity is set to adjustResize in the manifest  You can use a layout listener to see if the root layout of your activity is resized by the keyboard   I use something like the following base class for my activities   public class BaseActivity extends Activity       private ViewTreeObserver OnGlobalLayoutListener keyboardLayoutListener   new ViewTreeObserver OnGlobalLayoutListener              Override         public void onGlobalLayout                 int heightDiff   rootLayout getRootView   getHeight   - rootLayout getHeight                int contentViewTop   getWindow   findViewById Window ID ANDROID CONTENT  getTop                 LocalBroadcastManager broadcastManager   LocalBroadcastManager getInstance BaseActivity this                if heightDiff  lt   contentViewTop                   onHideKeyboard                     Intent intent   new Intent  KeyboardWillHide                    broadcastManager sendBroadcast intent                 else                   int keyboardHeight   heightDiff - contentViewTop                  onShowKeyboard keyboardHeight                    Intent intent   new Intent  KeyboardWillShow                    intent putExtra  KeyboardHeight   keyboardHeight                   broadcastManager sendBroadcast intent                                       private boolean keyboardListenersAttached   false      private ViewGroup rootLayout       protected void onShowKeyboard int keyboardHeight         protected void onHideKeyboard           protected void attachKeyboardListeners             if  keyboardListenersAttached                return                     rootLayout    ViewGroup  findViewById R id rootLayout           rootLayout getViewTreeObserver   addOnGlobalLayoutListener keyboardLayoutListener            keyboardListenersAttached   true              Override     protected void onDestroy             super onDestroy             if  keyboardListenersAttached                rootLayout getViewTreeObserver   removeGlobalOnLayoutListener keyboardLayoutListener                       The following example activity uses this to hide a view when the keyboard is shown and show it again when the keyboard is hidden   The xml layout    lt  xml version  1 0  encoding  utf-8   gt    lt LinearLayout xmlns android  http   schemas android com apk res android                android id    id rootLayout                android layout width  match parent                android layout height  match parent                android orientation  vertical  gt                      lt ScrollView         android id    id scrollView          android layout width  match parent          android layout height  0dp          android layout weight  1           gt            lt  -- omitted for brevity -- gt        lt  ScrollView gt        lt LinearLayout android id    id bottomContainer          android layout width  match parent          android layout height  wrap content          android orientation  vertical           gt            lt  -- omitted for brevity -- gt        lt  LinearLayout gt    lt  LinearLayout gt    And the activity   public class TestActivity extends BaseActivity        Override     protected void onCreate Bundle savedInstanceState            super onCreate savedInstanceState           setContentView R layout test activity            attachKeyboardListeners                Override     protected void onShowKeyboard int keyboardHeight               do things when keyboard is shown         bottomContainer setVisibility View GONE               Override     protected void onHideKeyboard                do things when keyboard is hidden         bottomContainer setVisibility View VISIBLE

Found an accurate way of telling whether or not a keyboard when using the  adjustResize  Soft input mode  Kotlin code  Define a couple of activity scope variables private var activityHeight   0 private var keyboardOpen   false  Write the following code in onCreate override fun onCreate savedInstanceState  Bundle             super onCreate savedInstanceState          setContentView R layout activity main                                   Grab initial screen value            this ActivityMain window decorView doOnNextLayout               val displayFrame   Rect   Rect               this ActivityMain window decorView getWindowVisibleDisplayFrame displayFrame              activityHeight   displayFrame height                         Check for keyboard open close            this ActivityMain window decorView addOnLayoutChangeListener   v  left  top  right  bottom  oldLeft  oldTop  oldRight  oldBottom - gt              val drawFrame   Rect   Rect               this ActivityMain window decorView getWindowVisibleDisplayFrame drawFrame              val currentSize   drawFrame height                keyboardOpen   currentSize  lt  activityHeight             Log v  quot keyboard1 quot   quot  keyboardOpen  currentSize -  activityHeight quot                You now have a boolean which accurately tracks whether or not the keyboard is open  do what you will

Jaap s answer won t work for AppCompatActivity   Instead get the height of the Status Bar and Navigation bar etc and compare to your app s window size   Like so       private ViewTreeObserver OnGlobalLayoutListener keyboardLayoutListener   new ViewTreeObserver OnGlobalLayoutListener          Override     public void onGlobalLayout                navigation bar height         int navigationBarHeight   0          int resourceId   getResources   getIdentifier  navigation bar height    dimen    android            if  resourceId  gt  0                navigationBarHeight   getResources   getDimensionPixelSize resourceId                         status bar height         int statusBarHeight   0          resourceId   getResources   getIdentifier  status bar height    dimen    android            if  resourceId  gt  0                statusBarHeight   getResources   getDimensionPixelSize resourceId                         display window size for the app layout         Rect rect   new Rect            getWindow   getDecorView   getWindowVisibleDisplayFrame rect               screen height -  user app height   status   nav        if non-zero  then there is a soft keyboard         int keyboardHeight   rootLayout getRootView   getHeight   -  statusBarHeight   navigationBarHeight   rect height              if  keyboardHeight  lt   0                onHideKeyboard              else               onShowKeyboard keyboardHeight

If you can  try to extend EditText and override  onKeyPreIme  method    Override public void setOnEditorActionListener final OnEditorActionListener listener        mEditorListener   listener    keep it for later usage     super setOnEditorActionListener listener       Override public boolean onKeyPreIme final int keyCode  final KeyEvent event        if  event getKeyCode      KeyEvent KEYCODE BACK  amp  amp  event getAction      KeyEvent ACTION UP            if  mEditorListener    null                  you can define and use custom listener                OR define custom R id  lt imeId gt                OR check event keyCode in listener impl                 I used editor action because of ButterKnife               mEditorListener onEditorAction this  android R id closeButton  event                       return super onKeyPreIme keyCode  event       How can you extend it    Implement onFocus listening and declare  onKeyboardShown  declare  onKeyboardHidden    I think  that recalculating of screen height is not 100  successfully as mentioned before  To be clear  overriding of  onKeyPreIme  is not called on  hide soft keyboard programatically  methods  BUT if you are doing it anywhere  you should do  onKeyboardHidden  logic there and do not create a comprehensive solutions

This is not working as desired         have seen many use size calculations to check       I wanted to determine if it was open or not and I found isAcceptingText    so this really does not answer the question as it does not address opening or closing rather more like is open or closed so it is related code that may help others in various scenarios     in an activity       if    InputMethodManager  getSystemService Context INPUT METHOD SERVICE   isAcceptingText              Log d TAG  Software Keyboard was shown          else           Log d TAG  Software Keyboard was not shown            in a fragment      if    InputMethodManager  getActivity   getSystemService Context INPUT METHOD SERVICE   isAcceptingText              Log d TAG  Software Keyboard was shown          else           Log d TAG  Software Keyboard was not shown

at the first create a kotlin file and add these methods  fun Activity getRootView    View       return findViewById lt View gt  android R id content    fun Context convertDpToPx dp  Float   Float       return TypedValue applyDimension              TypedValue COMPLEX UNIT DIP               dp               this resources displayMetrics         fun Activity isKeyboardOpen    Boolean       val visibleBounds   Rect       this getRootView   getWindowVisibleDisplayFrame visibleBounds      val heightDiff   getRootView   height - visibleBounds height       val marginOfError   Math round this convertDpToPx 50F       return heightDiff  gt  marginOfError    fun Activity isKeyboardClosed    Boolean       return  this isKeyboardOpen      then create a listener class for checking the keyboard is open or not   class KeyboardEventListener          private val activity  AppCompatActivity          private val callback   isOpen  Boolean  - gt  Unit     LifecycleObserver        private val listener   object   ViewTreeObserver OnGlobalLayoutListener        private var lastState  Boolean   activity isKeyboardOpen         override fun onGlobalLayout                 val isOpen   activity isKeyboardOpen               if  isOpen    lastState                    return               else                   dispatchKeyboardEvent isOpen                  lastState   isOpen                                   init              Dispatch the current state of the keyboard         dispatchKeyboardEvent activity isKeyboardOpen               Make the component lifecycle aware         activity lifecycle addObserver this          registerKeyboardListener             private fun registerKeyboardListener             activity getRootView   viewTreeObserver addOnGlobalLayoutListener listener            private fun dispatchKeyboardEvent isOpen  Boolean            when               isOpen  - gt  callback true               isOpen - gt  callback false                       OnLifecycleEvent value   Lifecycle Event ON PAUSE       CallSuper     fun onLifecyclePause             unregisterKeyboardListener             private fun unregisterKeyboardListener             activity getRootView   viewTreeObserver removeOnGlobalLayoutListener listener           and use it like this   override fun onResume           super onResume         KeyboardEventListener this    isOpen - gt     handle event        I hope you find it useful
