Android的菜单问题

尤其是android开发人员:) 我尝试创建应用程序菜单时遇到一些麻烦。Android的菜单问题

当我点击一些按钮 - apllication说过程中意外停止

我使它几乎像在手动这里（http://www.droidnova.com/creating-game-menus-in- android，518.html），但他们的示例作品和我的代码不是！我不明白我做错了什么，请问，有人可以帮忙吗？

main.xml中

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
android:id="@+id/widget32" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
android:background="@drawable/background" 
xmlns:android="http://schemas.android.com/apk/res/android" 
> 
<TableLayout 
android:id="@+id/widget28" 
android:layout_width="295px" 
android:layout_height="600px" 
android:orientation="vertical" 
android:layout_centerVertical="true" 
android:layout_centerHorizontal="true" 
> 
<Button 
android:id="@+id/StartGame" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:background="@drawable/startgame_button" 
> 
</Button> 
<TextView 
android:id="@+id/widget34" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
> 
</TextView> 
<Button 
android:id="@+id/Help" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:background="@drawable/help_button" 
> 
</Button> 
<TextView 
android:id="@+id/widget35" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
> 
</TextView> 
<Button 
android:id="@+id/Highscores" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
android:background="@drawable/highscores_button" 
> 
</Button> 
<TextView 
android:id="@+id/widget36" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content" 
> 
</TextView> 
<Button android:id="@+id/Quit" android:background="@drawable/quit_button" android:layout_height="wrap_content" android:layout_width="wrap_content"></Button> 

</TableLayout> 
</RelativeLayout>

startgame_button.xml例如

<?xml version="1.0" encoding="utf-8"?> 
<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/start_game_highlighted" /> 
    <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/start_game_pressed" /> 
    <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/start_game_pressed" /> 
    <item android:drawable="@drawable/start_game" /> 
</selector>

摩尼菜单活动

package game.mainmenu; 

import android.app.Activity; 
import android.content.Intent; 
import android.media.MediaPlayer; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.WindowManager; 
import android.widget.Button; 
import game.main.R; 

public class MainMenuActivity extends Activity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     final Activity t = this; 
     this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
       WindowManager.LayoutParams.FLAG_FULLSCREEN); 

     Button StartGameButton = (Button)findViewById(R.id.StartGame);//кнопка начала игры 
     StartGameButton.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       Intent StartGameIntent = new Intent(MainMenuActivity.this, StartGame.class); 
       startActivity(StartGameIntent); 
      } 
     }); 

     Button HelpButton = (Button)findViewById(R.id.Help);//кнопка help 
     HelpButton.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       Intent HelpIntent = new Intent(MainMenuActivity.this, Help.class); 
       startActivity(HelpIntent); 
      } 
     }); 

     Button OptionsButton = (Button)findViewById(R.id.Highscores);//кнопка 
     OptionsButton.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       Intent OptionsIntent = new Intent(MainMenuActivity.this, Highscores.class); 
       startActivity(OptionsIntent); 
      } 
     }); 

     Button QuitButton = (Button)findViewById(R.id.Quit);//кнопка 
     QuitButton.setOnClickListener(new OnClickListener() { 

      public void onClick(View v) { 
       t.finish(); 
      } 
     }); 


    } 


}

和示例StartGame活动

public class StartGame extends Activity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.copy);  

    } 
}

和copy.xml

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout 
android:id="@+id/widget32" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
xmlns:android="http://schemas.android.com/apk/res/android" 
> 

<TextView android:text="blah blah blah" 
android:id="@+id/TextView01" 
android:layout_width="wrap_content" 
android:layout_height="wrap_content"></TextView> 
</RelativeLayout>

UPD！

好的问题解决了！这是因为IDK为什么，但没有对活动的完整路径AndroidManifest

<activity android:name="game.mainmenu.Help"//like here. it dosen't work if it's just ".Help" 
        android:label="@string/app_name"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity>

请编辑您的问题与logcat堆栈跟踪，你得到 – Craigy

完成！哦，为了让你等待 - 这只是凌晨3点在这里，我有点下跌真的很困 – MarkMark

你有没有登记在体现你的班？每个想要用作意图的类都需要在清单中注册，否则应用程序将无法找到它。

像这样：

<activity android:name="Help" android:label="@string/app_name" 

     > 
     <intent-filter> 
      <action android:name="this.can.be.anything.unique" /> 
      <category android:name="android.intent.category.DEFAULT" /> 
     </intent-filter> 
    </activity>

行动机器人：名称设置，因此您可以通过名称而称它为不是通过Help.class调用它。

在你的代码这样，你可以这样调用它：

Intent helpIntent = new Intent("this.can.be.anything.unique"); 
startActivity(helpIntent);

但是，这是可选的。尽管如此，你必须在这个类的清单中有一个条目才能工作。

而且这是很好的做法，先设置你的标志，然后设置的内容...

final Activity t = this; 
    this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
      WindowManager.LayoutParams.FLAG_FULLSCREEN); 
    setContentView(R.layout.main);//move this here

如果这些方法都可以帮助，发表您的堆栈跟踪，所以我们可以看看还有什么可能是问题。
