Give your activity's root view a known ID, say '@+id/activityRoot', hook a GlobalLayoutListener into the ViewTreeObserver, and from there calculate the size diff between your activity's view root and the window size:
final View activityRootView = findViewById(R.id.activityRoot); activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() { @Override public void onGlobalLayout() { int heightDiff = activityRootView.getRootView().getHeight() - activityRootView.getHeight(); if (heightDiff > 100) { // if more than 100 pixels, its probably a keyboard... ... do something here } } });
