写法一：

 1 private OnTouchListener pressOnTouchListener = new OnTouchListener(){
 2 
 3         @Override
 4         public boolean onTouch(View view, MotionEvent event) {
 5             // TODO Auto-generated method stub
 6             switch (event.getAction()){
 7             case MotionEvent.ACTION_DOWN:
 8                 //按下
 9                 break;
10             case MotionEvent.ACTION_UP:
11                 //抬起
12                 break;
13                 
14             }
15             return false;
16         }
17         
18     };

写法二：

1     class myOntouchListener implements OnTouchListener{
2 
3         @Override
4         public boolean onTouch(View arg0, MotionEvent arg1) {
5             // TODO Auto-generated method stub
6             return false;
7         }
8         
9     }
