android - 闪屏 Android 应用已停止

Question

我想为我的 Android 应用制作启动画面。我在 android studio 的 welcomescreen.java 中编写了以下代码。但是运行应用程序后，应用程序停止了。 :( 我现在该怎么办？

package com.mateors.welcomescreen;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class WelcomeScreen extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_welcome_screen);
    Thread myThread = new Thread(){
        @Override
        public void run() {
            try {
                sleep(5000);
                Intent intent = new Intent(getApplicationContext(), MainActivity.class);
                startActivity(intent);
                finish();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }

        }
    };
    myThread.start();
}
}

private static int SPLASH_TIME_OUT = 1500;
     @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.splash_screen);


            new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    Intent i = new Intent(WelcomeScreen.this, MainActivity.class);
                    startActivity(i);
                    finish();
                }
            }, SPLASH_TIME_OUT);
        }
