Recyclerview inside ScrollView not scrolling smoothly

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);

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>

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.

Replacing ScrollView with NestedScrollView resulted into smooth scrolling to the bottom.

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

Kotlin

Set isNestedScrollingEnabled to false for every RecyclerView that is under the scrolling view

val recyclerView = findViewById<RecyclerView>(R.id.recyclerView)
recyclerView.isNestedScrollingEnabled = false

Using XML Layout

<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);

---

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!

you can use ScrollView as a parent and NestedScrollView as a child. like this:-

       <androidx.core.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/CL1">
        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/eventRV"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/CL1" />
    </androidx.core.widget.NestedScrollView>

---

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);

---

Or you can just set android:focusableInTouchMode="true" in your recycler view

This code is working for in ConstraintLayout android

Simple Add this line into your JAVA class

list.setNestedScrollingEnabled(false);

---

I myself had this issue, there is a recycler view within a scrollview and the scroll doesn't seem to be smooth. The cause for my issue was having the scrollview on top of the recycler view which was not needed for my requirement. So after I removed the scrollview and added the android:scrollbars="vertical" for recycler view, the scrolling was smooth.

---

After 3 days of research, I solved smooth scroll issue in my project.

The problem is <layer-list> drawable set in the background of item_user.xml file so it takes GPU time for rendering that's why scrolling not smooth. So please dont use complex <layer-list> drawable in the background of adapter item.

My problem is solved by above solution, below option is not useful for me

setNestedScrollingEnabled setHasFixedSize setItemViewCacheSize
