Aplikacja, którą utworzę, ma widok listy rozwijanej, w której dodałem opcję przeciągania, aby edytować i usunąć. Dodałem te opcje, ale gdy uruchamiam aplikację, robi to 't pokazuje opcję przesuwania, nawet gdy próbowałem z innym widokiem listy, ale działa poprawnie. Użyłem opcji machnięcia wewnątrz adaptera podstawowego, każdy może mi powiedzieć, dlaczego funkcja przeciągania nie działa w widoku listy rozwijanej.Swipeleft do usunięcia nie działa w widoku listy rozszerzalnej wysokości
