android 延时代码 android 延时方法

1、Handler的postDelayed方法

new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                //do what you want

            }
        }, 2000); //延时2秒

2、Timer + TimerTask方法

Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run() {
                //do what you want

            }
        }, 2000); //延时2秒

3、Thread的sleep方法

new Thread(new Runnable() {
            @Override
            public void run() {
                try {
                    Thread.sleep(2000); //延时2秒
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                //do what you want

            }
        }).start();

4、AlarmManager + Service(BroadcastReceiver)
