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);           
    }
});

谢谢你的回答，我找到了一个最适合我需要的解决方案。

Handler myHandler = new DoSomething();
Message m = new Message();
m.obj = c;//passing a parameter here
myHandler.sendMessageDelayed(m, 1000);

class DoSomething extends Handler {
    @Override
    public void handleMessage(Message msg) {
      MyObject o = (MyObject) msg.obj;
      //do something here
    }
}

final Handler handler = new Handler(); 
Timer t = new Timer(); 
t.schedule(new TimerTask() { 
    public void run() { 
        handler.post(new Runnable() { 
            public void run() { 
                //DO SOME ACTIONS HERE , THIS ACTIONS WILL WILL EXECUTE AFTER 5 SECONDS...
            }
        }); 
    } 
}, 5000); 

请看这个演示:

import java.util.Timer;
import java.util.TimerTask;

class Test {
     public static void main( String [] args ) {
          int delay = 5000;// in ms 

          Timer timer = new Timer();

          timer.schedule( new TimerTask(){
             public void run() { 
                 System.out.println("Wait, what..:");
              }
           }, delay);

           System.out.println("Would it run?");
     }
}

在Android中，我们可以编写下面的kotlin代码来延迟任何函数的执行

class MainActivity : AppCompatActivity() {

private lateinit var handler: Handler

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    handler= Handler()
    handler.postDelayed({
        doSomething()
    },2000)
}

private fun doSomething() {
    Toast.makeText(this,"Hi! I am Toast Message",Toast.LENGTH_SHORT).show()
}
}

你可以使用新引入的lambda表达式让它更简洁:

new Handler().postDelayed(() -> {/*your code here*/}, time);
