问题 I'm using a ViewPager2 with two fragments in a vertical orientation. When the user swipes down to the second fragment, there is a RecyclerView that scrolls content in the same vertical direction.

Now onClick on any of these items should open the DetailsFragment for that particular item. Basically the fragment needs to be refreshed.
