错误无法从CursorWindow读取行0列-1

我的应用程序在我的设备上运行时崩溃。据logcat中，光标无法读取CursorWindow，其中有2行2列的数据，下面的方法：错误无法从CursorWindow读取行0列-1

public ArrayList<Notes> getData() { 
      SQLiteDatabase db = this.getReadableDatabase(); 
     ArrayList<Notes> listNotes = new ArrayList<Notes>(); 
      result = db.rawQuery("SELECT * from " + NOTES_TABLE_NAME, new String[] {}); 
      if (result != null && result.getCount() > 0) { 
       if (result.moveToFirst()) { 
        do { 
        Notes note = new Notes(); 
        note.id = result.getInt(result.getColumnIndex(NOTES_COLUMN_ID)); 
        note.text = result.getString(result.getColumnIndex(NOTES_COLUMN_NAME)); 
        listNotes.add(note); 
       } while (result.moveToNext()); 
       } 
      } 
      result.close(); 
      return listNotes; 
    }

logcat的

是否确定列名是正确的，因为列-1意味着它无法找到列 –

列名是错误的。我改变了它，然后我忘了重命名它。谢谢！ – John

检查您的列名NOTES_COLUMN_ID因为result.getColumnIndex(NOTES_COLUMN_ID)返回-1，这意味着您的光标中找不到列名称。您在CREATE TABLE声明中使用的常量是否相同？
