如何在 Android 导航组件中从片段导航到活动？

Question

In navigation graph, i have an Activity(MainActivity) which contains 4 fragments. I navigate that fragments using bottomnavigation view through NAV Graph (JetPack Navigation) . I need to play video using Exo Player. So for that reason. i take a fragment which contains recyclerview of videolist. when i pass the intent from VideoListAdapter Class like

             Intent intent=new Intent(context,PlayVideo.class);
             context.startActivity(intent);

for playing full screen video in PlayVideo Actvity

it shows me error of marshal value, & parcel.write.os() , so what have to do?...Please help me.

Since you are using navigation component in your app I suggest that you should use fragments instead of Activity.

A quick fix for your problem would be to hide the bottom navigation view. You can access your bottom navigation using:

BottomNavigationView navBar = getActivity().findViewById(R.id.bottomBar);
