禁掉menu但是保留actionbar

在activity里面public boolean dispatchKeyEvent(KeyEvent event) {    final int keycode = event.getKeyCode();    final int action = event.getAction();    if (keycode == KeyEvent.KEYCODE_MENU && action == KeyEvent.ACTION_UP) {        return true; // consume the key press    }    return super.dispatchKeyEvent(event);}
