Java splash后出现Android Studio错误

我已经跟随和指导了4次，以使启动屏幕，但启动屏幕后，应用程序给出了一个错误，并关闭。启动屏幕上有一个停留4秒钟的图像，下一个屏幕上有一个webviewer，在查看器上方需要有标题栏。你知道吗

Android Honeycomb 3.0设置为默认值 Splash.java文件：

package nl.broodje.app.broodje;

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

/**
 * Created by Christiaan on 14-11-2015.

public class Splash extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.splash_screen);
        Thread myThread = new Thread(){
            @Override
            public void run() {
                try {
                    sleep(3000);
                    Intent startMainScreen = new Intent(getApplicationContext(), MainActivity.class);
                    startActivity(startMainScreen);
                    finish();
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        };
        myThread.start();

    }
}

splash_screen.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/logo"
            android:id="@+id/imageView"
            android:layout_gravity="center_vertical" />
</LinearLayout>

AndroidManifest.xml文件

<?xml version="1.0" encoding="utf-8"?>

由于

MainActivity扩展了AppCompatActivity

，并且您正在设置自己的

ActionBar

，

MainActivity

需要一个

NoActionBar

主题，就像启动屏幕一样

<activity android:name=".MainActivity"
    android:theme="@style/AppTheme.NoActionBar" />

请提供此类问题的stacktrace。也就是说，您是否在清单中列出了带有

NoActionBar

主题的

MainActivity

。清单添加在上面。我无法生成更多的代码块。所以我用空格。
