Recyclerview inside ScrollView not scrolling smoothly

For my app I am using a RecyclerView inside a ScrollView where the RecyclerView has a height based on its content using this library. Scrolling is working but it's not working smoothly when I scroll over the RecyclerView. When I scroll over the ScrollView itself it is scrolling smoothly.

The code I am using to define the RecyclerView:

LinearLayoutManager friendsLayoutManager = new LinearLayoutManager(getActivity().getApplicationContext(), android.support.v7.widget.LinearLayoutManager.VERTICAL, false);
mFriendsListView.setLayoutManager(friendsLayoutManager);
mFriendsListView.addItemDecoration(new DividerItemDecoration(getActivity().getApplicationContext(), null));

The RecyclerView in the ScrollView:

<android.support.v7.widget.RecyclerView
    android:layout_marginTop="10dp"
    android:layout_marginBottom="10dp"
    android:id="@+id/friendsList"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

Try doing:

RecyclerView v = (RecyclerView) findViewById(...);
v.setNestedScrollingEnabled(false);

As an alternative, you can modify your layout using the support design library. I guess your current layout is something like:

<ScrollView >
   <LinearLayout >

       <View > <!-- upper content -->
       <RecyclerView > <!-- with custom layoutmanager -->

   </LinearLayout >
</ScrollView >

You can modify that to:

<CoordinatorLayout >

    <AppBarLayout >
        <CollapsingToolbarLayout >
             <!-- with your content, and layout_scrollFlags="scroll" -->
        </CollapsingToolbarLayout >
    </AppBarLayout >

    <RecyclerView > <!-- with standard layoutManager -->

</CoordinatorLayout >

However this is a longer road to take, and if you are OK with the custom linear layout manager, then just disable nested scrolling on the recycler view.

Edit (4/3/2016)

The v 23.2 release of the support libraries now includes a factory “wrap content” feature in all default LayoutManagers. I didn’t test it, but you should probably prefer it to that library you were using.

<ScrollView >
   <LinearLayout >

       <View > <!-- upper content -->
       <RecyclerView > <!-- with wrap_content -->

   </LinearLayout >
</ScrollView >

I only needed to use this:

mMyRecyclerView.setNestedScrollingEnabled(false);

in my onCreateView() method.

Thanks a lot!

You can use this way either :

Add this line to your recyclerView xml file :

android:nestedScrollingEnabled="false"

Or in java code :

RecyclerView.setNestedScrollingEnabled(false);

Hope this helped .

You can try with both the ways with XML and programmatically. But the issue you may face is (below API 21) by doing it with XML will not work . So it's better to set it programmatically in your Activity / Fragment.

XML code:

<android.support.v7.widget.RecyclerView
      android:id="@+id/recycleView"
      android:layout_width="match_parent"
      android:visibility="gone"
      android:nestedScrollingEnabled="false"
      android:layout_height="wrap_content"
      android:layout_below="@+id/linearLayoutBottomText" /> 

Programmatically:

 recycleView = (RecyclerView) findViewById(R.id.recycleView);
 recycleView.setNestedScrollingEnabled(false);
