Android 延时执行任务的三种简单方法

时间:2021-06-15 21:19:37
  1. 开启一个新的线程
      new Thread() {
    @Override
    public void run() {
    try {
    Thread.sleep(2000);
    } catch (InterruptedException e) {
    e.printStackTrace();
    }
    startActivity(new Intent(LeadActivity.this, WelcomeActivity.class));
    }
    }.start();

      

  2. handler 加 postDelayed 
     handler.postDelayed(new Runnable() {
    @Override
    public void run() {
    startActivity(new Intent(LeadActivity.this, WelcomeActivity.class));
    }
    },3000);
    }

      

  3. 定时器  TimerTask  和 Timer
     TimerTask task = new TimerTask() {
    @Override
    public void run() {
    startActivity(new Intent(LeadActivity.this, WelcomeActivity.class));
    }
    };
    Timer timer = new Timer();
    timer.schedule(task,1000);
    }
