AppBar with Fragments and Bottom Navigation Bar

Question

Not sure if I'm fighting an uphill battle but I'm currently struggling with AppBar, Fragments and Bottom Navigation Bars.

I have a MainActivity that's a list view with an AppBar. It's created as a fragment with the intention to add another bottom navigation bar here in the future.

For now, when an item in the list is clicked it navigates to a detail view fragment. Here I still have the AppBar which is what I want however I would like to add a Bottom Navigation Bar. However when I navigate to the next fragment I lose my bottom navigation bar.

Is there a way to keep maintain Bottom Navigation Bars within Fragments? I tried breaking them out into activities but discovered then I lose my AppBar.

Is what I'm doing above feasible in Android?

Ideally I'd like this:

Answer 1

Do you have different nav graphs for different fragments? You need to have the detail view fragment in the same nav graph as the bottom navigation view. You don't need to have another item in bottom navigation but declare fragments that you want with bottom navigation in the same nav graph.
