Soft keyboard open and close listener in an activity in Android

Piece of cake with the awesomeKeyboardVisibilityEvent 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() {@Overridepublic void onFocusChange(View v, boolean hasFocus) {        if (hasFocus) {            //got focus        } else {            //lost focus        }   }});
