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);
