Tak więc w mojej aplikacji na Androida mam główną aktywność, która ma zakładki, a na każdej karcie znajduje się fragment zawierający widok listy. Ale z jakiegoś powodu ostatni element listy jest zawsze odcięty. Rozglądałem się za rozwiązaniami, ale nie znalazłem jeszcze żadnych. Jakieś sugestie?Ostatnia pozycja na liście jest obcięta

Czy w końcu zmieniłeś się w RecyclerView?Wygląda na to, że nie można używać ArrayAdapter z RecyclerView, co jest frustrujące. – jaynp
