1.利用handler

1）定义Handler

Handler handler = new Handler() {public void handleMessage(Message msg) {switch (msg.what) {case 1:break;}super.handleMessage(msg);}};

2）Handler中的postDelayed

handler.postDelayed(new Runnable() {                    public void run() {     //execute the task                       }                }, 3000);

其中，3000表示延迟的时间，单位为毫秒。

2.利用TimerTask

1)定义TimerTask

TimerTask task = new TimerTask(){      public void run() {          Message message = new Message();              message.what = 1;              handler.sendMessage(message);        }          }; 

2)用timer调用事件

Timer timer = new Timer();   timer.schedule(task, 50); 

3.android view中的postDelayed

v.postDelayed(new Runnable() {                      public void run() {                           }                  }, 30);
