177.n1-banner的监听

banner的监听只需要添加点击事件

//监听image的点击事件image.setOnTouchListener(new OnTouchListener(){@Overridepublic boolean onTouch(View v, MotionEvent event) {switch(event.getAction()){case MotionEvent.ACTION_DOWN://清除所有的消息和回掉mHandler.removeCallbacksAndMessages(null);/*//主线程巡行mHandler.post(new Runnable(){@Overridepublic void run() {// TODO Auto-generated method stub}});*/break;//按键的时候移动到其他地方并抬起，取消按键case MotionEvent.ACTION_CANCEL:mHandler.sendEmptyMessageDelayed(0, 3000);break;case MotionEvent.ACTION_UP:mHandler.sendEmptyMessageDelayed(0, 3000);break;default:break;}return true;}});
