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);
