Recycler View с GridLayoutManager без прокрутки

Приложение содержит две кнопки, одну для ListView, а другую для GridView, поэтому я создал для ItemViews и один адаптер. Я создал метод переключения между ListView и GridView. Все работает нормально, кроме GridView, который, кажется, забит. Просмотр списка прокручивается по вертикали, но только до 6 элементов, список содержит 9. Я хочу, чтобы GridView прокручивался так же, как прокручивается до конца в представлении списка. Я потратил 2 часа одновременно на поиск решения, но ни один из них не сработал. Я пробовал ScrollView, NestedScrollView, но все еще не могу решить.

Вид сетки = RecyclerView с GridLayoutManager

Вот скриншот:

Этот отлично работает до 6 элементов и скрывает 3 из 9

Этот не прокручивается (только GridView)

Вот код:
