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(false) function to the recyclerview like this while setting adapter.

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