android 实现点击listview 空白地方隐藏菜单

思路：重写ListView的setOnTouchListener事件；

         ListView.setOnTouchListener(new OnTouchListener(){
 
             @Override
             public boolean onTouch(View arg0, MotionEvent arg1) {
                 // TODO Auto-generated method stub
                 hideMenu();//隐藏菜单
                 return false;
             }
 
         });

延申：

点击窗体空白地方隐藏菜单或软键盘思路一样:

     @Override
     public boolean onTouchEvent(MotionEvent event) {
         // TODO Auto-generated method stub
         hideMenu();
         return super.onTouchEvent(event);
 
     }
