Soft keyboard open and close listener in an activity in Android

Android Android Activity Android Edittext Android Softkeyboard

Android Problem Overview

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?

Piece of cake with the awesome KeyboardVisibilityEvent library

KeyboardVisibilityEvent.setEventListener(
    getActivity(),
    new KeyboardVisibilityEventListener() {
        @Override
        public void onVisibilityChanged(boolean isOpen) {
            // Ah... at last. do your thing :)
        }
    });

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 <= 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:

<?xml version="1.0" encoding="utf-8"?>

<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">              

    <ScrollView
        android:id="@+id/scrollView"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        >

        <!-- omitted for brevity -->

    </ScrollView>

    <LinearLayout android:id="@+id/bottomContainer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <!-- omitted for brevity -->

    </LinearLayout>

</LinearLayout>

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);
    }        
}

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
        }
   }
});

For Activity:

    final View activityRootView = findViewById(R.id.activityRoot);
activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
			@Override
			public void onGlobalLayout() {
				Rect r = new Rect();
				
				activityRootView.getWindowVisibleDisplayFrame(r);

				int heightDiff = view.getRootView().getHeight() - (r.bottom - r.top);
				if (heightDiff > 100) { 
                 //enter your code here
				}else{
                 //enter code for hid
                }
			}
		});

For Fragment:

    view = inflater.inflate(R.layout.live_chat_fragment, null);
view.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.
				view.getWindowVisibleDisplayFrame(r);

				int heightDiff = view.getRootView().getHeight() - (r.bottom - r.top);
				if (heightDiff > 500) { // if more than 100 pixels, its probably a keyboard...

				}
			}
		});

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 > 0) {
            navigationBarHeight = getResources().getDimensionPixelSize(resourceId);
        }

        // status bar height
        int statusBarHeight = 0;
        resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
        if (resourceId > 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 <= 0) {
            onHideKeyboard();
        } else {
            onShowKeyboard(keyboardHeight);
        }
    }
};

You can try it:

private void initKeyBoardListener() {
    // Минимальное значение клавиатуры. 
    // Threshold for minimal keyboard height.
    final int MIN_KEYBOARD_HEIGHT_PX = 150;
    // Окно верхнего уровня view. 
    // Top-level window decor view.
    final View decorView = getWindow().getDecorView();
    // Регистрируем глобальный слушатель. Register global layout listener.
    decorView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        // Видимый прямоугольник внутри окна. 
        // Retrieve visible rectangle inside window.
        private final Rect windowVisibleDisplayFrame = new Rect();
        private int lastVisibleDecorViewHeight;

        @Override
        public void onGlobalLayout() {
            decorView.getWindowVisibleDisplayFrame(windowVisibleDisplayFrame);
            final int visibleDecorViewHeight = windowVisibleDisplayFrame.height();

            if (lastVisibleDecorViewHeight != 0) {
                if (lastVisibleDecorViewHeight > visibleDecorViewHeight + MIN_KEYBOARD_HEIGHT_PX) {
                    Log.d("Pasha", "SHOW");
                } else if (lastVisibleDecorViewHeight + MIN_KEYBOARD_HEIGHT_PX < visibleDecorViewHeight) {
                    Log.d("Pasha", "HIDE");
                }
            }
            // Сохраняем текущую высоту view до следующего вызова.
            // Save current decor view height for the next call.
            lastVisibleDecorViewHeight = visibleDecorViewHeight;
        }
    });
}

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 "Hide" 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, "keyboard opened",Toast.LENGTH_SHORT).show();
else 
  Toast.makeText(MainActivity.this, "keyboard hidden", 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);

The below code is working for me,

mainLayout.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            if (mainLayout != null) {
                int heightDiff = mainLayout.getRootView().getHeight() - mainLayout.getHeight();
                if (heightDiff > dpToPx(getActivity(), 200)) { 
                   //keyboard is open
                } else {
                   //keyboard is hide
                }
            }
        }
    });

Solution 9 - Android

You can use my Rx extension function (Kotlin).

/**
 * @return [Observable] to subscribe of keyboard visibility changes.
 */
fun AppCompatActivity.keyboardVisibilityChanges(): Observable<Boolean> {

    // flag indicates whether keyboard is open
    var isKeyboardOpen = false

    val notifier: BehaviorSubject<Boolean> = BehaviorSubject.create()

    // approximate keyboard height
    val approximateKeyboardHeight = dip(100)

    // device screen height
    val screenHeight: Int = getScreenHeight()

    val visibleDisplayFrame = Rect()

    val viewTreeObserver = window.decorView.viewTreeObserver

    val onDrawListener = ViewTreeObserver.OnDrawListener {

        window.decorView.getWindowVisibleDisplayFrame(visibleDisplayFrame)

        val keyboardHeight = screenHeight - (visibleDisplayFrame.bottom - visibleDisplayFrame.top)

        val keyboardOpen = keyboardHeight >= approximateKeyboardHeight

        val hasChanged = isKeyboardOpen xor keyboardOpen

        if (hasChanged) {
            isKeyboardOpen = keyboardOpen
            notifier.onNext(keyboardOpen)
        }
    }

    val lifeCycleObserver = object : GenericLifecycleObserver {
        override fun onStateChanged(source: LifecycleOwner, event: Lifecycle.Event?) {
            if (source.lifecycle.currentState == Lifecycle.State.DESTROYED) {
                viewTreeObserver.removeOnDrawListener(onDrawListener)
                source.lifecycle.removeObserver(this)
                notifier.onComplete()
            }
        }
    }

    viewTreeObserver.addOnDrawListener(onDrawListener)
    lifecycle.addObserver(lifeCycleObserver)

    return notifier
            .doOnDispose {
                viewTreeObserver.removeOnDrawListener(onDrawListener)
                lifecycle.removeObserver(lifeCycleObserver)
            }
            .onTerminateDetach()
            .hide()
}

Example:

(context as AppCompatActivity)
                    .keyboardVisibilityChanges()
                    .subscribeBy { isKeyboardOpen ->
                        // your logic
                    }

Solution 10 - Android

For use in Kotlin inside fragment, which is a common use case it is very easy with KeyboardVisibilityEvent library.

In build.gradle:

implementation 'net.yslibrary.keyboardvisibilityevent:keyboardvisibilityevent:3.0.0-RC2'

In Fragment:

activity?.let {
    KeyboardVisibilityEvent.setEventListener(it,object: KeyboardVisibilityEventListener {
        override fun onVisibilityChanged(isOpen: Boolean) {
            if (isOpen) Toast.makeText(context,"Keyboard is opened",Toast.LENGTH_SHORT).show()
            else Toast.makeText(context,"Keyboard is closed",Toast.LENGTH_SHORT).show()
        }
    })
}

Solution 11 - Android

in kotlin you can use this code in your activity

window.decorView.viewTreeObserver.addOnGlobalLayoutListener{
    val r = Rect()
    window.decorView.getWindowVisibleDisplayFrame(r)
 
        val height =window.decorView.height
        if(height - r.bottom>height*0.1399){
           //keyboard is open
      }else{
            //keyboard is close
      }

Solution 12 - Android

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 && event.getAction() == KeyEvent.ACTION_UP) {
        if (mEditorListener != null) {
            //you can define and use custom listener,
            //OR define custom R.id.<imeId>
            //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 will work without any need to change your activity's android:windowSoftInputMode

step 1: extend EditText class and override these two:

@Override
public void setOnEditorActionListener(final OnEditorActionListener listener) {
    mEditorListener = listener;
    super.setOnEditorActionListener(listener);
}

@Override
public boolean onKeyPreIme(final int keyCode, final KeyEvent event) {
    if (event.getKeyCode() == KeyEvent.KEYCODE_BACK && event.getAction() == KeyEvent.ACTION_UP) {
        if (mEditorListener != null) {
            mEditorListener.onEditorAction(this, android.R.id.closeButton, event);
        }
    }
    return super.onKeyPreIme(keyCode, event);
}

step 2: create these two in your activity:

private void initKeyboard() {
    final AppEditText editText = findViewById(R.id.some_id);
    editText.setOnFocusChangeListener(new OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            setKeyboard(hasFocus);
        }
    });
    editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if (event == null || event.getKeyCode() == KeyEvent.KEYCODE_BACK) {
                editText.clearFocus();
            }
            return false;
        }
    });
}

public void setKeyboard(boolean isShowing) {
    // do something
}

*** remember in order to make clearFocus work, you have to make parent or first child in the parent hierarchy focusable.

    setFocusableInTouchMode(true);
    setFocusable(true);

In Android Manifest, android:windowSoftInputMode="adjustResize" is necessary.

Somewhere else in your code

/*
Instantiate and pass a callback

SoftKeyboard softKeyboard;
softKeyboard = new SoftKeyboard(mainLayout, im);
softKeyboard.setSoftKeyboardCallback(new SoftKeyboard.SoftKeyboardChanged() {

@Override
public void onSoftKeyboardHide()  {
	// Code here
}

@Override
public void onSoftKeyboardShow() {
	// Code here

});

/*
Open or close the soft keyboard easily

softKeyboard.openSoftKeyboard();
softKeyboard.closeSoftKeyboard();

/* Prevent memory leaks:*/
@Override

For the case of adjustResize and FragmentActivity accepted solution from @Jaap doesn't work for me.

Here is my solution:

private ViewTreeObserver.OnGlobalLayoutListener keyboardLayoutListener = new ViewTreeObserver.OnGlobalLayoutListener() {
    private int contentDiff;
    private int rootHeight;
    @Override
    public void onGlobalLayout() {
        View contentView = getWindow().findViewById(Window.ID_ANDROID_CONTENT);
        if (rootHeight != mDrawerLayout.getRootView().getHeight()) {
            rootHeight = mDrawerLayout.getRootView().getHeight();
            contentDiff = rootHeight - contentView.getHeight();
            return;
        }
        int newContentDiff = rootHeight - contentView.getHeight();
        if (contentDiff != newContentDiff) {
            if (contentDiff < newContentDiff) {
                onShowKeyboard(newContentDiff - contentDiff);
            } else {
                onHideKeyboard();
            }
            contentDiff = newContentDiff;
        }
    }
};

Solution 17 - Android

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() > 0) {
            timeoutHandler.postDelayed(typingRunnable, TYPING_TIMEOUT);
        }
    }
});

This code works great nice

use this class for root view:

public class KeyboardConstraintLayout extends ConstraintLayout {

private KeyboardListener keyboardListener;
private EditText targetEditText;
private int minKeyboardHeight;
private boolean isShow;

public KeyboardConstraintLayout(Context context) {
    super(context);
    minKeyboardHeight = getResources().getDimensionPixelSize(R.dimen.keyboard_min_height); //128dp
}

public KeyboardConstraintLayout(Context context, AttributeSet attrs) {
    super(context, attrs);
    minKeyboardHeight = getResources().getDimensionPixelSize(R.dimen.keyboard_min_height); // 128dp
}

public KeyboardConstraintLayout(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);
    minKeyboardHeight = getResources().getDimensionPixelSize(R.dimen.keyboard_min_height); // 128dp
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    if (!isInEditMode()) {
        Activity activity = (Activity) getContext();
        @SuppressLint("DrawAllocation")
        Rect rect = new Rect();
        getWindowVisibleDisplayFrame(rect);

        int statusBarHeight = rect.top;
        int keyboardHeight = activity.getWindowManager().getDefaultDisplay().getHeight() - (rect.bottom - rect.top) - statusBarHeight;

        if (keyboardListener != null && targetEditText != null && targetEditText.isFocused()) {
            if (keyboardHeight > minKeyboardHeight) {
                if (!isShow) {
                    isShow = true;
                    keyboardListener.onKeyboardVisibility(true);
                }
            }else {
                if (isShow) {

public interface KeyboardListener {

        @Override
        public void onKeyboardVisibility(boolean isVisible) {

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");

    }

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 21 - Android

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 ->
            val drawFrame : Rect = Rect()
            this@ActivityMain.window.decorView.getWindowVisibleDisplayFrame(drawFrame)
            val currentSize = drawFrame.height()

            keyboardOpen = currentSize < activityHeight
            Log.v("keyboard1","$keyboardOpen $currentSize - $activityHeight")
        }
}

You now have a boolean which accurately tracks whether or not the keyboard is open, do what you will

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.

when keyboard show

rootLayout.getHeight() < rootLayout.getRootView().getHeight() - getStatusBarHeight()

is true,else hide

Solution 25 - Android

private boolean isKeyboardShown = false;
private int prevContentHeight = 0;
private ViewGroup contentLayout;

private ViewTreeObserver.OnGlobalLayoutListener keyboardLayoutListener =
        new ViewTreeObserver.OnGlobalLayoutListener() {

    @Override
    public void onGlobalLayout() {
        int contentHeight = contentLayout.getHeight();
        int rootViewHeight = contentLayout.getRootView().getHeight();

        if (contentHeight > 0) {

            if (!isKeyboardShown) {
                if (contentHeight < prevContentHeight) {
                    isKeyboardShown = true;
                    onShowKeyboard(rootViewHeight - contentHeight);
                }
            } else {
                if (contentHeight > prevContentHeight) {
                    isKeyboardShown = false;
                    onHideKeyboard();
                }
            }

            prevContentHeight = contentHeight;
        }
    }
};

I've modified the Jaap's accepted answer a bit. But in my case, there are few assumptions such as android:windowSoftInputMode=adjustResize and the keyboard does not show up at the beginning when the app starts. And also, I assume that the screen in regard matches the parent's height.

contentHeight > 0 this check provides me to know if the regarding screen is hidden or shown to apply keyboard event listening for this specific screen. Also I pass the layout view of the regarding screen in attachKeyboardListeners(<your layout view here>) in my main activity's onCreate() method. Every time when the height of the regarding screen changes, I save it to prevContentHeight variable to check later whether the keyboard is shown or hidden.

For me, so far it's been worked pretty well. I hope that it works for others too.

Solution 26 - Android

"Jaap van Hengstum"'s answer is working for me, but there is no need to set "android:windowSoftInputMode" as he just said!

I've made it smaller(it now just detects what I want, actually an event on showing and hiding of keyboard):

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();
        if(heightDiff <= contentViewTop){
            onHideKeyboard();
        } else {
            onShowKeyboard();
        }
    }
};

private boolean keyboardListenersAttached = false;
private ViewGroup rootLayout;

protected void onShowKeyboard() {}
protected void onHideKeyboard() {}

protected void attachKeyboardListeners() {
    if (keyboardListenersAttached) {
        return;
    }

    rootLayout = (ViewGroup) findViewById(R.id.CommentsActivity);
    rootLayout.getViewTreeObserver().addOnGlobalLayoutListener(keyboardLayoutListener);

    keyboardListenersAttached = true;
}

@Override
protected void onDestroy() {
    super.onDestroy();

    if (keyboardListenersAttached) {
        rootLayout.getViewTreeObserver().removeGlobalOnLayoutListener(keyboardLayoutListener);
    }
}

and just don't forget to add this

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_comments);
    attachKeyboardListeners();}

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);

I built the listener using https://stackoverflow.com/a/25681196/15431984">this</a> answer and my task https://github.com/vipercreation/Viper-Pack/blob/master/documentation%20%5BLoopingTask%5D.md">LoopingTask</a>;, thanks by the way.

Very easy to implement using https://github.com/vipercreation/Viper-Pack/blob/master/documentation%20%5BLava%5D.md#softkeyboardlistener-">SoftKeyboardListener</a> from https://github.com/vipercreation/Viper-Pack">Viper Pack android library.

Just install the library then add this to your code :

Lava.app.addSoftKeyboardListener(context, new Lava.SoftKeyboardListener() {
@Override
public void onSoftKeyboardShow(EditText focusedview) {
// when shows
}
@Override
public void onSoftKeyboardHide(EditText focusedview) {
// when hides
}
});

Dislaimer : adding a lot of listeners may slow/crash your app, you still can use `Lava.app.removeSoftKeyboardListeners()` to remove all the previous listeners.

Dislaimer 2 : creating a SoftKeyboardListener directly in activity `onCreate` will add a new one every time the activity resume itself, so make sure to limit that using a boolean :

boolean isListenerAdded;
...
@Override
public void onCreate(Bundle sis) {
super.onCreate(sis);
...
if (!isListenerAdded) {
isListenerAdded = true;
// create your listener here
}
...
}
...

Or just remove all the previous ones :

...
@Override
public void onCreate(Bundle sis) {
super.onCreate(sis);
...
Lava.app.removeSoftKeyboardListeners();
// create your listener here
...
}
...

Lava.app.removeSoftKeyboardListeners() removes all previous SoftKeyboardListeners.

Solution 30 - Android

at the first create a kotlin file and add these methods:

fun Activity.getRootView(): View {
    return findViewById<View>(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 > 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) -> 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  -> callback(true)
            !isOpen -> 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 -> // handle event }

I hope you find it useful.

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!! < contentFullWeight) {
            Log.d("TEZT_KEYBOARD", ">> KBD OPENED")
        } else {
            Log.d("TEZT_KEYBOARD", ">> KBD closed")
        }
    })

}

Dislaimer : adding a lot of listeners may slow/crash your app, you still can use `Lava.app.removeSoftKeyboardListeners()` to remove all the previous listeners.

Dislaimer 2 : creating a SoftKeyboardListener directly in activity `onCreate` will add a new one every time the activity resume itself, so make sure to limit that using a boolean :
