Question

Android出现错误，但没有出现任何红色错误标记。问题标签指出：Android包装问题。我不知道该怎么做....请帮助.......

我正在编写一本题为“24小时学习Android”的书。这是一个简单的游戏，名为“在那里，完成了！”。它有7个不同的活动：

1.QuizHelpActivity：

package com.android.triviaquiz; 
import android.os.Bundle; 
public class QuizSplashActivity extends QuizActivity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.help); 

2.QuizSplashActivity：

package com.android.triviaquiz; 
import android.os.Bundle; 
public class QuizSplashActivity extends QuizActivity { 
    /** Called when the activity is first created. */ 
     @Override 
    public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.splash); 

3.QuizGameActivity：

package com.android.triviaquiz; 
import android.os.Bundle; 
public class QuizSplashActivity extends QuizActivity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.game); 

4.QuizScoreActivity：

package com.android.triviaquiz; 
import android.os.Bundle; 
public class QuizSplashActivity extends QuizActivity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.score); 

5.QuizSettingsActivity：

package com.android.triviaquiz; 
import android.os.Bundle; 
public class QuizSplashActivity extends QuizActivity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.settings); 

6.QuizMenuActivity：

package com.android.triviaquiz; 
import android.os.Bundle; 
public class QuizSplashActivity extends QuizActivity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.menu); 

7.and他们都延长QuizActivity：

package com.android.triviaquiz; 
    import android.app.Activity; 

    public class QuizActivity extends Activity{ 
public static final String GAME_PREFERENCES="GamePrefs";
