Answer 1

This is what working for me

<android.support.v4.widget.NestedScrollView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/rv_recycler_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
</android.support.v4.widget.NestedScrollView>

I have used this awesome extension (written in kotlin but can be also used in Java)

https://github.com/Widgetlabs/expedition-nestedscrollview

Basically you get the NestedRecyclerView inside any package lets say utils in your project, then just create your recyclerview like

 <com.your_package.utils.NestedRecyclerView
      android:id="@+id/rv_test"
      android:layout_width="match_parent"
      android:layout_height="match_parent" />

There are a lot of good answers. The key is that you must set nestedScrollingEnabled to false. As mentioned above you can do it in java code:

mRecyclerView.setNestedScrollingEnabled(false);

But also you have an opportunity to set the same property in xml code (android:nestedScrollingEnabled="false"):

 <android.support.v7.widget.RecyclerView
 android:id="@+id/recyclerview"
 android:nestedScrollingEnabled="false"
 android:layout_width="match_parent"
 android:layout_height="match_parent" />

For my case the child of NestedScrollview is ConstraintLayout. It is not working as expected i replaced it to LinearLayout. Maybe it helps someone.

<androidx.core.widget.NestedScrollView 
  android:id="@+id/nestedScrollView" 
  android:layout_width="match_parent" 
  android:layout_height="match_parent">

  <LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:descendantFocusability="blocksDescendants">

    <androidx.recyclerview.widget.RecyclerView
      android:id="@+id/recyclerView"
      android:layout_width="0dp"
      android:layout_height="wrap_content"
      android:nestedScrollingEnabled="false"
      app:layout_constraintBottom_toTopOf="@+id/divider"
      app:layout_constraintEnd_toEndOf="parent"
      app:layout_constraintStart_toStartOf="parent"
      app:layout_constraintTop_toBottomOf="@+id/tinTitle"/>

  </LinearLayout>
</androidx.core.widget.NestedScrollView>

You can't use a recycler view within a nested scroll view. It's not intended to contain further scrollable views but it's because it's a child of a scrolling layout itself that you need the nested scrolling view. I had the same issue but in the end I moved my textview to be a headerview within the recyclerview, made the recyclerview a direct child of the coordinator layout and deleted the nested scroll view. Then all my problems were gone.

Here is the code that I'm using to avoid scrolling issues:

mRecyclerView = (RecyclerView) view.findViewById(android.R.id.list);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
mRecyclerView.getLayoutManager().setAutoMeasureEnabled(true);
mRecyclerView.setNestedScrollingEnabled(false);
mRecyclerView.setHasFixedSize(false);
