Android中几种延后处理事件的方法

 

一、Handler和TimerTask相结合

1、首先定义TimerTask

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

2、定义Handler

 

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

3、用timer调用事件

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

二、Android中自带的postDelayed

1、android view中的postDelayed

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

2、Handler中的postDelayed

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