从CursorWindow读取错误

Question

我有一个listView，其中包含笔记制作应用程序的注释标题。我正在尝试实现itemclicklistener来打开相应的注释。    这是SQLite表创建代码：

        public static final String TABLE_NAME = "notes";
        public static final String KEY_ID = "_id";
        public static final String DATA = "data";
        public static final String TITLE = "title";
String CREATE_TABLE = "create table " + TABLE_NAME + "(" + KEY_ID + " integer primary key autoincrement,"
            + DATA + " text not null,"
            + TITLE + " text not null"
            + " ) ; ";

以下是获取数据的代码：

 mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Cursor cursor = (Cursor) mListView.getItemAtPosition(position);
                String data = (cursor.getString(2));

问题是当我将1传递给cursor.getString（1）方法时，我得到了标题，而我应该在将2传递给同一个数据时获取数据，抛出游标初始化错误。
