Cześć. Mam taki problem. Posiadam RecyclerView, w którym itemy rozszerzają się po naciśnięciu oraz posiadają button który pozwala użytkownikowi dodać/usunąć się z tego obiektu. Niestety, raz na jakiś czas metoda getAdapterPosition() zwraca -1 przez co program się wysypuje.
Czy wiecie może jak to obejść, albo co robie tutaj źle ?
