在我的例子中，我不能用其他答案。 我使用本机java定时器代替。

new Timer().schedule(new TimerTask() {          
    @Override
    public void run() {
        // this code will be executed after 2 seconds       
    }
}, 2000);

对活动类的另一个响应(java8)。

//hide with delay
new Thread(() -> {
    try {Thread.sleep(500);} catch (InterruptedException e) {e.printStackTrace();}
    this.runOnUiThread(() -> {
        myView.setVisibility(View.GONE);//this run on GUI
    });
}).start();

我创建了一个更简单的方法来调用它。

public static void CallWithDelay(long miliseconds, final Activity activity, final String methodName)
    {
        new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {
                try {
                    Method method =  activity.getClass().getMethod(methodName);
                    method.invoke(activity);
                } catch (NoSuchMethodException e) {
                    e.printStackTrace();
                } catch (InvocationTargetException e) {
                    e.printStackTrace();
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                }
            }
        }, miliseconds);
    }

要使用它，只需调用:.CallWithDelay(5000，这个，"DoSomething");

android中合适的解决方案:

private static long SLEEP_TIME = 2 // for 2 second
.
.
MyLauncher launcher = new MyLauncher();
            launcher.start();
.
.
private class MyLauncher extends Thread {
        @Override
        /**
         * Sleep for 2 seconds as you can also change SLEEP_TIME 2 to any. 
         */
        public void run() {
            try {
                // Sleeping
                Thread.sleep(SLEEP_TIME * 1000);
            } catch (Exception e) {
                Log.e(TAG, e.getMessage());
            }
            //do something you want to do
           //And your code will be executed after 2 second
        }
    }

5秒后在UI线程中执行一些东西:

new Handler(Looper.getMainLooper()).postDelayed(new Runnable() {
    @Override
    public void run() {
        //Do something here
    }
}, 5000);

Kotlin & Java多种方式

1. 使用处理程序

Handler().postDelayed({
    TODO("Do something")
    }, 2000)

2. 使用TimerTask

Timer().schedule(object : TimerTask() {
    override fun run() {
        TODO("Do something")
    }
}, 2000)

或者更短

Timer().schedule(timerTask {
    TODO("Do something")
}, 2000)

或者说最短的是

Timer().schedule(2000) {
    TODO("Do something")
}

3.使用执行人

Executors.newSingleThreadScheduledExecutor().schedule({
    TODO("Do something")
}, 2, TimeUnit.SECONDS)

在Java中

1. 使用处理程序

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        //Do something
    }
}, 2000);

2. 使用定时器

new Timer().schedule(new TimerTask() {          
    @Override
    public void run() {
        // Do something
    }
}, 2000);

3.使用ScheduledExecutorService

private static final ScheduledExecutorService worker = Executors.newSingleThreadScheduledExecutor();

Runnable runnable = new Runnable() {
  public void run() {
      // Do something
  }
  };
worker.schedule(runnable, 2, TimeUnit.SECONDS);
