Question

Answer 1

Two things, you need to do.

1. Wrap up recyclerviews inside nested scrollview.

    <androidx.core.widget.NestedScrollView android:layout_width="match_parent" android:layout_height="match_parent" android:scrollbars="vertical" android:fillViewport="true"> //<RecyclerView 1> //<RecyclerView 2> //<RecyclerView 3> </androidx.core.widget.NestedScrollView>

2. And then call setNestedScrollingEnabled function to the recyclerview like this while setting adapter.

 recycler1.isNestedScrollingEnabled = false recycler2.isNestedScrollingEnabled = false recycler3.isNestedScrollingEnabled = false
