KeyboardLayoutListener Example for when you need to hide views or do something when the keyboard is up without relying in the onFocus, also to deal for when you have an item outside your scroll view and the keyboard pulls all the things up

BaseActivity.java

//Import Utils from somewhere

public class BaseActivity extends Activity {
    private ViewTreeObserver.OnGlobalLayoutListener keyboardLayoutListener = new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
          int navigationBarHeight = Utils.getNavigationBarHeight(BaseActivity.this);
          int statusBarHeight = Utils.getStatusBarHeight(BaseActivity.this);
          
          // 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);
          }
        }
    };

    private ViewGroup rootLayout;

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

        if (keyboardListenersAttached) {
