问题 Currently, I am playing around Android Navigation Component with Bottom Navigation Bar. While playing I realized two facts: Fragments are always recreated ( onCreate , onViewCreated , onViewDestroyed are called as soon as the user navigates to another fragment) savedInstanceState is always null (in onCreate , onViewCreated , etc.) The first issue can be fixed by using custom FragmentNavigator , which will reuse fragment if it already exists package am.chamich.apps.advancedbottomnavigation
