以下语句cursor.moveToNext()始终为false.我希望循环执行一次.我已经测试过查询实际返回的数据.

有谁知道是什么事吗？

    String query ="SELECT(SELECT COUNT(*) FROM Table1) as count1, (SELECT COUNT(*) FROM Table2) as count2;";

    Cursor mCursor = mDb.rawQuery(query, null);

    if (mCursor != null) {
        mCursor.moveToFirst();
    }

    while (cursor.moveToNext()) {   //<---------------return false here???
        String result_0=cursor.getString(0);
    }
