APP продолжает сбой, пытаясь заполнить активность B другой информацией [дублировать] ⇐ Android

[Anonymous]

У меня приложение настроено, поэтому, когда я нажимаю на представление об переработке, правильно просмотреть переходы изображений фильма на активность B. Теперь, когда я пытаюсь заполнить информацию об объекте в активности B (например, сюжет и т. Д.) Я получаю Ошибка говорит, что то, что у меня есть в Bindviewholder, является нулевым. Я, должно быть, что -то упускаю, потому что то, как у меня было приложение, настраивалось раньше (вся информация на одной карте) все было запрашивалось правильно и отображалось. Все начало происходить, когда я решил изменить и отправить информацию в действие b. < /P>
