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");

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);

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
        }
    }

以下是我的最短解决方案:

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        //Do something after 100ms
    }
}, 100);

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);

你可以使用这个最简单的解决方案:

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        //Write your code here
    }
}, 5000); //Timer is in ms here.

否则，下面可能是另一个干净有用的解决方案:

new Handler().postDelayed(() -> 
{/*Do something here*/}, 
5000); //time in ms
