android OnTouchListener 按下与抬起

写法一：

 private OnTouchListener pressOnTouchListener = new OnTouchListener(){

         @Override
         public boolean onTouch(View view, MotionEvent event) {
             // TODO Auto-generated method stub
             switch (event.getAction()){
             case MotionEvent.ACTION_DOWN:
                 //按下
                 break;
             case MotionEvent.ACTION_UP:
                 //抬起
                 break;

             }
             return false;
         }

     };

写法二：

     class myOntouchListener implements OnTouchListener{

         @Override
         public boolean onTouch(View arg0, MotionEvent arg1) {
             // TODO Auto-generated method stub
             return false;
         }

     }
