雙擊事件

class onDoubleClick implements View.OnTouchListener{  
  
    @Override  
    public boolean onTouch(View v, MotionEvent event) {  
        if(MotionEvent.ACTION_DOWN == event.getAction()){  
            count++;  
            if(count == 1){  
                firClick = System.currentTimeMillis();  
                  
            } else if (count == 2){  
                secClick = System.currentTimeMillis();  
                if(secClick - firClick < 1000){  
                    //雙擊事件  
                      
                }  
                count = 0;  
                firClick = 0;  
                secClick = 0;  
                  
            }  
        }  
        return true;  
    }
