У меня есть просмотр списка, когда я изменяю значение одного элемента (счетчика) нажатием кнопки «плюс», все в порядке, пока пользователь прокручивает вниз и показывает больше элементов. И мы видим это на каждой странице прокрутки. изменил значение предмета !!! Я не знаю, почему все выглядит хорошо!

создать список по активности
