應用程序在Android中意外停止

我正在使用SQLite應用程序。我的申請是開放的任何其他活動。應用程序在Android中意外停止

下面是代碼

public class hotornot { 
     public static final String KEY_ROWID = "_id"; 
     public static final String KEY_NAME = "persons_name"; 
     public static final String KEY_HOTNESS = "persons_hotness"; 
     private static final String DATABASE_NAME = "HotorNotdb"; 
     private static final String DATABASE_TABLE = "peopletable"; 
     private static final int DATABASE_VERSION = 1; 
     private DbHelper ourHelper; 
     private final Context ourcontext; 
     private SQLiteDatabase ourDatabase; 

     private static class DbHelper extends SQLiteOpenHelper { 

      public DbHelper(Context context) { 
       super(context, DATABASE_NAME, null, DATABASE_VERSION); 
      } 

      @Override 
      public void onCreate(SQLiteDatabase db) { 
       // TODO Auto-generated method stub 
       db.execSQL("CREATE TABLE " + DATABASE_TABLE + " (" + KEY_ROWID 
         + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_NAME 
         + " TEXT NOT NULL, " + KEY_HOTNESS + " TEXT NOT NULL);" 

       ); 
      } 

      @Override 
      public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
       // TODO Auto-generated method stub 
       db.execSQL("DROP TABLE IF EXISTS " + DATABASE_TABLE); 
       onCreate(db); 
      } 

     } 

     public hotornot(Context c) { 
      ourcontext = c; 
     } 

     public hotornot open() throws SQLException { 
      ourHelper = new DbHelper(ourcontext); 
      ourDatabase = ourHelper.getWritableDatabase(); 
      return this; 
     } 

     public void close() { 
      ourHelper.close(); 
     } 

     public Long createentry(String name, String hotness) { 
      ContentValues cv = new ContentValues(); 
      cv.put(KEY_NAME, name); 
      cv.put(KEY_HOTNESS, hotness); 
      return ourDatabase.insert(DATABASE_TABLE, null, cv); 
     } 

     public String getdata() { 
      // TODO Auto-generated method stub 
      String[] columns = new String[] { KEY_ROWID, KEY_NAME, KEY_HOTNESS }; 
      Cursor c = ourDatabase.query(DATABASE_TABLE, columns, null, null, null, 
        null, null); 
      String result = ""; 

      int iRow = c.getColumnIndex(KEY_ROWID); 
      int iName = c.getColumnIndex(KEY_NAME); 
      int iHotness = c.getColumnIndex(KEY_HOTNESS); 

      for (c.moveToFirst(); !c.isAfterLast(); c.moveToNext()) { 
       result = result + c.getString(iRow) + " " + c.getString(iName) 
         + " " + c.getString(iHotness) + "\n"; 
      } 

      return result; 
     } 
    }

這裏是清單文件：

<activity 
    android:name=".sqliteexample" 
    android:label="@string/app_name" > 
    <intent-filter> 
     <action android:name="android.intent.action.MAIN" /> 
     <category android:name="android.intent.category.LAUNCHER" /> 
    </intent-filter> 

</activity> 
<activity 
    android:name=".sview" 
    android:label="@string/app_name" > 
    <intent-filter> 
     <action android:name="org.sqlite.SVIEW" /> 
     <category android:name="android.intent.category.DEFAULT" /> 
    </intent-filter> 
</activity>

和logcat的：

在你的eclipse中，轉到窗口>顯示視圖>文件資源管理器，並在數據> data> yourPackageName中檢出數據庫是否存在，如果不存在，則必須導入數據庫文件。

是的，我已經檢查過，數據庫存在那裏。感謝有關文件資源管理器的信息。 – dan 2012-07-29 01:05:52

試試這個

ourHelper = new DbHelper(ourcontext); 
    ourDatabase = ourHelper.getWritableDatabase(); 
    ourHelper .onCreate(ourDatabase);

我已經試過這個，但我發現一個異常，當我檢查logcat的錯誤顯示數據庫已經創建。但好處是，這次我得到了一個異常，而不是應用程序關閉的錯誤消息。當我撤銷編輯的部分，我的應用程序運行良好。意思是隻有一個非技術性錯誤。謝謝:) – dan 2012-07-29 01:02:07

我覺得DbHelper定義是wrong.It想的是：

public DbHelper(Context context, String name, 
       CursorFactory factory, int version) { 
      super(context, name, factory, version); 
      // TODO Auto-generated constructor stub 
     }

和修改

private static final String DATABASE_NAME = "HotorNotdb.db";

請嘗試。

我已經嘗試過，但這需要在每個類的變化。我剛剛清理並刷新我的應用程序並執行。它運行良好然後:)謝謝:) – dan 2012-07-29 01:04:36
