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);

使用CountDownTimer非常简单。 详情https://developer.android.com/reference/android/os/CountDownTimer.html

import android.os.CountDownTimer;

// calls onTick every second, finishes after 3 seconds
new CountDownTimer(3000, 1000) { 

   public void onTick(long millisUntilFinished) {
      Log.d("log", millisUntilFinished / 1000);
   }

   public void onFinish() {
      // called after count down is finished
   } 
}.start();

你可以在UIThread中使用Handler:

runOnUiThread(new Runnable() {
                
    @Override
    public void run() {
        new Handler().postDelayed(new Runnable() {
           @Override
           public void run() {
               //add your code here
          }
        }, 1000);           
    }
});

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

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
        }
    }
