Как я могу объединить мой BottomNavigationView с навигационным ящиком

/ 10 марта 2020

Поскольку я использовал оба BottomNavigationView и NavigationDrawer в моем приложении, но возникает проблема, когда я помещаю кнопку Home в них обоих (BottomNavigationView и NavigationDrawer), кнопка для Navigation Drawer работает хорошо, но при использовании Home (Dashboard) из BottomNavigationView есть проблема возникает, когда я щелкаю по любой из карт, просматриваю cardView после выбора Home из BottomNavigationView, затем приложение падает, но работает хорошо, когда я открываю его из NavigationDrawer.

Вот ошибка:

java .lang.IllegalArgumentException: место назначения навигации com.appsnipp.admin: id / action_nav_home_to_nav_resource неизвестно этому NavController

Изображения приложения

Просмотр из дома из BottomNavigationView BottomNavigationView

Ящик навигации Ящик навигации Вот мои коды !!

Таким образом, проблема была в том, где я создал дубликат фрагмента в файле навигации как nav_home navB_home, но во время навигации я всегда перемещался из nav_home Так, чтобы преодолеть эту проблему, я удалил navB_home из навигации и из меню и вздутый nav_home там (BottomNavigationView) Так что пока и NavigationView, и BottomNavigationView имеют ту же навигацию по фрагментам, что и nav_home.
