如何在android中的视图上听doubletap?

我想检测一个视图上的doubletap,比如一个按钮,然后知道它是哪个视图.我见过this similar question,但他们说这是一个重复的问题似乎没有回答我的问题.

我只能find将GestureDetector添加到活动中,并向其添加一个OnDoubleTapListener.但只有在我点击屏幕的背景/布局时才会触发.当我(双击)按钮时不会触发它.

这是我在onCreate中的代码:

    gd = new GestureDetector(this, this);


    gd.setOnDoubleTapListener(new OnDoubleTapListener()  
    {  
        @Override  
        public boolean onDoubleTap(MotionEvent e)  
        {  
            Log.d("OnDoubleTapListener", "onDoubleTap");
            return false;  
        }  

        @Override  
        public boolean onDoubleTapEvent(MotionEvent e)  
        {  
            Log.d("OnDoubleTapListener", "onDoubleTapEvent");
            //if the second tap hadn't been released and it's being moved  
            if(e.getAction() == MotionEvent.ACTION_MOVE)  
            {  

            }  
            else if(e.getAction() == MotionEvent.ACTION_UP)//user released the screen  
            {  

            }  
            return false;  
        }  

        @Override  
        public boolean onSingleTapConfirmed(MotionEvent e)  
        {  
            Log.d("OnDoubleTapListener", "onSingleTapConfirmed");
            return false;  
        }  
    });
