Question

我用菜单屏幕和启动画面制作了游戏。我按照YouTube教程中的步骤进行操作。在闪屏结束后（当菜单屏幕应该出现时），应用程序每次都会崩溃。

这是我的代码，没有错误。问题出在哪里？

启动画面：

package com.group5.littlered;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;


public class MyMain extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

    //Remove title bar
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);

    //Remove notification bar
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

   //set content view AFTER ABOVE sequence (to avoid crash)
    this.setContentView(R.layout.main|R.layout.splash); 
    setContentView(R.layout.splash);
    Thread timer = new Thread(){
        public void run(){
            try{
                sleep(5000);
            } catch (InterruptedException e){
                e.printStackTrace();
            }finally{
                Intent openStartingPoint = new Intent("com.group5.littlered.STARTINGPOINT");
                startActivity(openStartingPoint);               
                }   
        }
    };
    timer.start();
}

@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    finish();
  }
}

菜单屏幕：

package com.group5.littlered;

import android.app.Activity;
import android.os.Bundle;

public class MyMenu extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
}}

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name=".MyMenu"
        android:label="@string/app_name"
        android:screenOrientation="landscape"

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

</application>

Answer 1

试试这个..

改变这个..

Intent openStartingPoint = new Intent("com.group5.littlered.STARTINGPOINT");
startActivity(openStartingPoint);

到

Intent openStartingPoint = new Intent(MyMain.this,MyMenu.class);
startActivity(openStartingPoint);

启动画面后应用程序崩溃（当菜单屏幕出现时）
