如何在android中区分longpress和singletap？

Question

我有一个纸牌游戏，我希望单击以在卡片上执行操作，而卡片上的长按则显示卡片的更大图像。我知道有GestureListener，但我该如何使用它？这是我的代码：

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;  
        }  
    });

错误... yourCard.setOnLongClickListener（）？
