When I implement my app using MVVM architecture. I always have a question of where should I put implementations of PagerAdapter and RecyclerViewAdapter. Now I put into Fragments as inner class.

I think It does not matter because they are a helper class, but I think you should not put them in activity/frament as an inner class, because they can make this class bigger, just put them into the same package with activity/frament.

It does not depend on MVVM architecture. The best practice is you should not put Adapter class as an inner class. Just put them in the same package.
