android應用程序不會啓動

我試圖調試我的菜單活動，但它似乎不能顯示輸出。屏幕上的錯誤信息表示儲蓄指南（我的應用程序名稱）已停止工作。如果我從android菜單手動點擊我的應用程序，它說我的應用程序沒有安裝。但是，我的代碼中沒有錯誤。任何人都可以幫助我？android應用程序不會啓動

我的菜單活動代碼：

public class SavingsGuiderMenuActivity extends SavingsActivity { 
/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.menu); 
    ListView menuList = (ListView) findViewById(R.id.ListView_Menu); 
    String[] items = { getResources().getString(R.string.start), 
      getResources().getString(R.string.about), 
      getResources().getString(R.string.help) }; 
    ArrayAdapter<String> adapt = new ArrayAdapter<String>(this, R.layout.menu_item, items); 
    menuList.setAdapter(adapt); 
    menuList.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     public void onItemClick(AdapterView<?> parent, View itemClicked, int position, long id) { 
      // Note: if the list was built "by hand" the id could be used. 
      // As-is, though, each item has the same id 
      TextView textView = (TextView) itemClicked; 
      String strText = textView.getText().toString(); 
      if (strText.equalsIgnoreCase(getResources().getString(R.string.start))) { 
       // Launch the app Activity 
       startActivity(new Intent(SavingsGuiderMenuActivity.this, SavingsGuiderAppActivity.class)); 
      } else if (strText.equalsIgnoreCase(getResources().getString(R.string.help))) { 
       // Launch the Help Activity 
       startActivity(new Intent(SavingsGuiderMenuActivity.this, SavingsGuiderHelpActivity.class)); 
      } else if (strText.equalsIgnoreCase(getResources().getString(R.string.about))) { 
       // Launch the about Activity 
       startActivity(new Intent(SavingsGuiderMenuActivity.this, SavingsGuiderAboutActivity.class)); 
      } 
     } 
    }); 
}

}

我的清單：

<application 
    android:label="@string/splash" 
    android:debuggable="true" 
    android:icon="@drawable/saving"> 
    <activity 
     android:name=".SavingsGuiderMenuActivity"

       android:name="android.intent.action.MAIN" /> 
      <category 
       android:name="android.intent.category.LAUNCHER" /> 
     </intent-filter> 
    </activity>

查看logcat並從強制關閉應用程序的異常中發佈堆棧跟蹤。 – FoamyGuy 2012-07-22 02:41:38

我的logcat有很多錯誤，而且我看到他們中的大多數與數組適配器有關，還有線性佈局，相對等等，就好像我的xml佈局是我的問題的原因。那可能嗎？ – honeybee 2012-07-22 03:10:04

可能是，編輯你的問題，併發布logcat我們將能夠幫助你更多。 – FoamyGuy 2012-07-22 03:11:02

不是你的xml是好的我認爲。如果你想創建一個菜單來選擇不同的活動，這可能不是最好的方法。

String classes[] = {"class_a","class_b","class_c"}; 
String class = classes[position]; Class ourClass=Class.forName("package_name"+class); 
Intent intent = new Intent(Menu.this,ourClass); 
startActivity(intent);

試試這在您的onItemClicked（）在嘗試括號。

String class = classes [position]; Class ourClass = Class.forName（「package_name」+ class）; <<我在'String class'變量中標記的錯誤包含forName括號內的變量... – honeybee 2012-07-22 03:38:39

String class = classes [position]; Class ourClass = Class.forName（「example.package.com」+ class）; 它工作正常。你是否把它放在帶有catch子句的try brackets中？ – 2012-07-22 03:44:13

它說，當我將鼠標懸停時，字符串不能解析爲變量。我認爲eclipse讀取我的字符串數據類型作爲變量..？ – honeybee 2012-07-22 03:53:56

您還使用了三個你的類的代碼即薩文gsGuiderAppActivity.java，SavingsGuiderHelpActivity.java和SavingsGuiderAboutActivity.java。您還需要在清單中註冊它們。你的清單應該看起來像這樣：

<application 
android:label="@string/splash" 
android:debuggable="true" 
android:icon="@drawable/saving"> 
<activity 
    android:name=".SavingsGuiderMenuActivity" 
    android:label="@string/splash"> 
    <intent-filter> 
     <action 
      android:name="android.intent.action.MAIN" /> 
     <category 
      android:name="android.intent.category.LAUNCHER" /> 
    </intent-filter> 
</activity> 
<activity 
    android:name=".SavingsGuiderAppActivity" 
    android:label="@string/splash"> 
<intent-filter> 
     <action 
      android:name="ACTIVITY_A" /> 
     <category 
      android:name="android.intent.category.DEFAULT" /> 
    </intent-filter> 
</activity> 
<activity 
    android:name=".SavingsGuiderHelpActivity" 
    android:label="@string/splash"> 
<intent-filter> 
     <action 
      android:name="ACTIVITY_B" /> 
     <category 
      android:name="android.intent.category.DEFAULT" /> 
    </intent-filter> 
</activity> 
<activity 
    android:name=".SavingsGuiderAboutActivity" 
    android:label="@string/splash"> 
<intent-filter> 
     <action 
      android:name="ACTIVITY_C" /> 
     <category 
      android:name="android.intent.category.DEFAULT" /> 
    </intent-filter> 
</activity>

謝謝@Adnan Zahid。我註冊了，但我的應用程序仍然是'未安裝'。我不知道問題出在哪裏。 – honeybee 2012-07-22 02:59:33

嘗試上面的編輯。嘗試了 – 2012-07-22 03:02:34

。是因爲我的XML佈局有問題或什麼，這就是爲什麼它說我的應用程序沒有安裝？ – honeybee 2012-07-22 03:08:10
