nie trzeba rozciąga StatisticFragment jak ViewPagerBottomSheetDialogFragment lub nie ma potrzeby korzystania z dowolnej biblioteki na to.
to ty kod mam tylko kilka zmian w swojej Static Fragment związanych View Pager.
Oto Statistic Fragment, w którym dokonano zmian.
Nie ma żadnych błędów, jak stwierdzono we wszystkich powyższych Odpowiedzi.
Należy zamienić ten kod na stary Static fragment tylko na inne zmiany, które dadzą pożądane dane wyjściowe.
Wprowadziłem tylko zmiany z Twoim View Pager i sprawiłem, że działał tak, jak chcesz. używana metoda OnPageChangeListener po prostu uzyskaj ten widok.

to zrobić.
Im nie zagrać jej pompowania poprawnie. Czy masz ustawione na pionowe? – MNM
Sprawdź moją odpowiedź poniżej nie ma żadnej dodatkowej biblioteki używanej, nie ma błędów, jak podano w innych odpowiedziach, po prostu sprawdź mój kod 'Static Fragment' i zastosuj to do twojego. –
