推荐答案

如果我不是你说的这个方法

If I am not you talking about this method

public boolean onKeyDown(int keyCode, KeyEvent event) {
super.onKeyDown(keyCode, event);
    switch(keyCode)
    {

    case KeyEvent.KEYCODE_BACK:
     Toast.makeText(KeyActions.this, "Pressed Back Button", Toast.LENGTH_SHORT).show();

        return true;
    }

    return false;
}
