Динамически Android Spinner

Question

Я создал динамически спиннер на основе этой ссылки:

https://www.androidtutorialpoint.com/basics/dynamically-add-and-remove-views-in-android

Вращатель извлекает данные из таблицы sqlite, здесь моя функция на dbhelper:

//getting all location from database
public List<String> getAllFlock()
{
    List<String> flockList=new ArrayList<>();
    //get readable database
    SQLiteDatabase db=this.getReadableDatabase();
    Cursor cursor=db.rawQuery("SELECT name FROM flock",null);
    if(cursor.moveToFirst())
    {
        do {
            flockList.add(cursor.getString(0));
        }while (cursor.moveToNext());
    }
    //close the cursor
    cursor.close();
    //close the database
    db.close();
    return flockList;
}

и вот мой код активности:

}

    LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    // Add the new row before the add field button.
    parentLinearLayoutAge.addView(rowView, parentLinearLayoutAge.getChildCount() - 1);
}
}

Первый счетчик успешно получает данные, а второй и после не может получить данные из таблицы.

Как это исправить?
