[編輯] 代碼：

public String getOfflineData(String type){ 
    String offlineData = null; Cursor cursor = null; 
    SQLiteDatabase db = this.getReadableDatabase(); 
    try { 
     cursor = db.rawQuery("select datavalue from offline_data where type='"+type+"'", null); 
     if(cursor.moveToFirst()) { 
      offlineData= cursor.getString(0); 
     } 
     cursor.close(); 
    } catch(Exception e) { 
     e.printStackTrace(); 
    } finally { 
     if(cursor!=null) cursor.close(); 
     db.close(); 
    } 
    return offlineData; 
}

您已經使用SQLite的，然後你沒有關閉DATABSE這就是爲什麼這個錯誤發生的事情，查線71 LoginHelper.java並在處理程序，如果你已經打開的SQLite有那麼使用 –

後關閉它，我已關閉我的數據庫，但它並沒有爲我工作 –

你可以顯示你的SQLite類，你已經實現OpenDBHelper –

您必須關閉數據庫連接。使用以下結構。

SQLiteDatabase db = mSQLiteOpenHelper.getWritableDatabase(); 
try { 
    -- 
    -- 
} catch(Exception e){ 
    e.printStackTrace(); 
} finally { 
    db.close(); 
}

感謝您的回答我的工作 –

如果我不想在每筆交易後關閉它，該怎麼辦？我想保持它打開，直到應用程序停止。我怎樣才能阻止這個警告？ –
