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" />
This question is related to
android
android-recyclerview
android-scrollview
android-scroll
I had similar issues (I tried to create a nested RecyclerViews something like Google PlayStore design). The best way to deal with this is by subclassing the child RecyclerViews and overriding the 'onInterceptTouchEvent' and 'onTouchEvent' methods. This way you get complete control of how those events behave and eventually scrolling.
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 .
Replacing ScrollView with NestedScrollView resulted into smooth scrolling to the bottom.

This code is working for in ConstraintLayout android
XML code:
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clipToPadding="false" />
</android.support.v4.widget.NestedScrollView>
in java code :
recycleView = (RecyclerView) findViewById(R.id.recycleView);
recycleView.setNestedScrollingEnabled(false);
Summary of all answers (Advantages & Disadvantages)
For single recyclerview
you can use it inside Coordinator layout.
Advantage - it will not load entire recyclerview items. So smooth loading.
Disadvantage - you can't load two recyclerview inside Coordinator layout - it produce scrolling problems
reference - https://stackoverflow.com/a/33143512/3879847
For multiple recylerview with minimum rows
you can load inside NestedScrollView
Advantage - it will scroll smoothly
Disadvantage - It load all rows of recyclerview so your activity open with delay
reference - https://stackoverflow.com/a/33143512/3879847
For multiple recylerview with large rows(more than 100)
You must go with recyclerview.
Advantage - Scroll smoothly, load smoothly
Disadvantage - You need to write more code and logic
Load each recylerview inside main recyclerview with help of multi-viewholders
ex:
MainRecyclerview
-ChildRecyclerview1 (ViewHolder1) -ChildRecyclerview2 (ViewHolder2) -ChildRecyclerview3 (ViewHolder3) -Any other layout (ViewHolder4)
Reference for multi-viewHolder - https://stackoverflow.com/a/26245463/3879847
Using Nested Scroll View instead of Scroll View solved my problem
<LinearLayout> <!--Main Layout -->
<android.support.v4.widget.NestedScrollView>
<LinearLayout > <!--Nested Scoll View enclosing Layout -->`
<View > <!-- upper content -->
<RecyclerView >
</LinearLayout >
</android.support.v4.widget.NestedScrollView>
</LinearLayout>
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);
Simple Add this line into your JAVA class
list.setNestedScrollingEnabled(false);
If you are using VideoView or heavy weight widgets in your childviews keep your RecyclerView with height wrap_content
inside a NestedScrollView with height match_parent
Then scrolling will work smooth as perfectly as you want it.
FYI,
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:nestedScrollingEnabled="false"
android:layout_height="wrap_content"
android:clipToPadding="false" />
</android.support.v4.widget.NestedScrollView>
Thanks Micro this was from your hint!

Set isNestedScrollingEnabled
to false
for every RecyclerView that is under the scrolling view
val recyclerView = findViewById<RecyclerView>(R.id.recyclerView)
recyclerView.isNestedScrollingEnabled = false
<android.support.v7.widget.RecyclerView
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:id="@+id/friendsList"
android:layout_width="match_parent"
android:nestedScrollingEnabled="false"
android:layout_height="wrap_content" />
Every answer is same here. and i already used what everyone is suggested. Then i found that NestedScrollView is faster then ScrollView so
use
<androidx.core.widget.NestedScrollView
Instead of
<ScrollView
And use this as usual
recycleView.setNestedScrollingEnabled(false);
Or you can just set android:focusableInTouchMode="true"
in your recycler view
