RecyclerView last item is cut off onResume of fragment

Question

Problem

RecyclerView functions properly and no view is cut when not opening a detailFragment. But it cuts off the last item of my RecylerView item whenever I return back from the detailFragment launched by the recylcerview item.

I only encounter this on my emulator which api 26. When I run it in my api 28 phone it works properly. But I think I might be missing something.

fragment_main

    <androidx.recyclerview.widget.RecyclerView

            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toTopOf="parent"/>
</androidx.constraintlayout.widget.ConstraintLayout>

NOTE

I wish not to put bottom padding for my recyclerView. I have tried this and it works but during the times that my recyclerView functions properly an excess padding is seen at the bottom
I wish not to make use of nestedScrollView for my recyclerView if possible since I would like the recyclerView to recycle as much as possible

Replacing

app:layout_scrollFlags="scroll|exitUntilCollapsed"

with

app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed"

solved my issue.

This removes the intended behavior of the toolbar sticking to the top while scrolling. If you want to keep this behavior, add `android:paddingBottom="?attr/actionBarSize"` to your scrolling view instead. – omiwrench May 17 '21 at 15:18
