RecyclerView inside Scroll View in the fragment is not working? [duplicate]

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);

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!
karthik

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

How to scroll whole activity

I wrote an application and home page is LinearLayout and is in Fragment. In this LinearLayout there are two RecyclerViews and SearchBar etc. I want to scroll whole activity. I spent 2 days for it but cannot succeed. How can I do that in easy way? There are lots of adapters and connections in that LinearLayout. How can I achieve that without broke any code.
I want to scroll whole activity.
Thanks in advance.

Set Scroll/NestedScrollView as a parent view in xml to scroll whole layout.
Add below attribute in recycler view to stop recycler scroll:
android:overScrollMode="never"
Try below code:
<android.support.v4.widget.NestedScrollView
android:id="#+id/navigation_nested"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:overScrollMode="never">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:padding="#dimen/margin_15">
<TextView
android:id="#+id/video_tv"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/margin_15"
android:drawableLeft="#drawable/ic_video_tutorial"
android:drawablePadding="#dimen/margin_20"
android:fontFamily="#font/poppins"
android:paddingLeft="#dimen/text_15"
android:text="#string/videos"
android:textColor="#color/blackTextColor"
android:textSize="#dimen/text_15" />
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:overScrollMode="never" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>

You just add this line:
//java
yourRecyclerView.setLayouManager(new LinearLayoutManager(this));
//kotlin
yourRecyclerView.layoutManager = LinearLayoutManager(this)
or from xml:
app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
Notice that there is not only LinearLayoutManager. If you are using a Grid RecyclerView than you might want to use GridLayoutManager

I solved the problem.
Just write ScrollView over the LinearLayout
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout>
.....
</LinearLayout>
</ScrollView>

Seekbar in recyclerview also moves recyclerview

Basically i have implemented recyclerview in nested scroll view which contains the arc seek bar in each item of recyclerview. So when i move seekbar recyclerview is also scrolling.
I tried using nestedscrollview and focusableInTouchMode option but did not worked.
device_list.apply {
device_list.layoutManager = GridLayoutManager(this#RoomActivity, 2)
device_list.adapter = DeviceAdapter()
}
<androidx.core.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?android:attr/actionBarSize"
android:background="#color/colorWhite">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/device_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/marginSemiGlobal"
android:layout_marginBottom="#dimen/marginSemiGlobal"
android:overScrollMode="never"
android:nestedScrollingEnabled="false"
android:scrollbars="none" />
</androidx.core.widget.NestedScrollView>
<com.marcinmoskala.arcseekbar.ArcSeekBar
app:roundEdges="true"
android:layout_width="match_parent"
android:layout_below="#+id/top_layout"
app:progressBackgroundColor="#color/colorProgressBackground"
app:progressBackgroundWidth="8dp"
app:progressColor="#color/colorProgress"
android:id="#+id/dimmer"
app:progressWidth="8dp"
android:layout_height="100dp"
app:thumb="#drawable/ic_progress_thumb"
android:layout_centerHorizontal="true" />
I tried setting setNestedScrollview to ViewCompact and also used focus in touch mode but output was same.

RecyclerView doesnot scroll when not nested in NestedScrollView but is in the same LinearLayout

I am using the following layout, but unable to get the RecyclerView to scroll(it is not visible on the screen when using this layout, scrolling stops till the NestedScrollView).
I can scroll up to the NestedScrollView and the CollapsingToolbar to collapse, if I remove the entire NestedScrollView then I get the RecyclerView to scroll.
If I keep the linear layout without the NestedScrollView, only the RecyclerView scrolls, the rest of the layout is fixed.
I have also added app:layout_behavior="#string/appbar_scrolling_view_behavior" to the RecyclerView, and have kept the RecyclerView out of the NestedScrollView.
If I add the RecyclerView inside the NestedScrollView, the RecyclerView does not appear.

android:layout_width="match_parent"
android:layout_height="wrap_content"

app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</LinearLayout>

Ok, if you want to add RecyclerView inside NestedScrollView add this line into RecyclerView in xml file app:layoutManager="LinearLayoutManager".
Example
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/your_recyclerview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layoutManager="LinearLayoutManager"/>
</android.support.v4.widget.NestedScrollView>
Then in your SomeActivity.java file where you populate RecyclerView put this line recyclerView.setNestedScrollingEnabled(false); before you setting adapter to RecyclerView.
Example
RecyclerView recyclerView=(RecyclerView)findViewById(R.id.your_recyclerview);
recyclerView.setNestedScrollingEnabled(false);
recyclerView.setAdapter(yourAdapter);

I solved it by nesting RecyclerView inside the NestedScrollView and updating the support library for recyclerview
I was using com.android.support:recyclerview-v7:23.0.1
as of Android Support Library, revision 23.2.0 (February 2016)
(refer revision archive here)
Changes for v7 RecyclerView library:
RecyclerView now has an opt-in feature called AutoMeasure which allows RecyclerView.LayoutManager to easily wrap content or
handle various measurement specifications provided by the parent of
the RecyclerView. It supports all existing animation capabilities of
the RecyclerView.
If you have a custom RecyclerView.LayoutManager, call setAutoMeasureEnabled(true) to start using the new AutoMeasure API.
All built-in RecyclerView.LayoutManager objects enable auto-measure by
default.
RecyclerView.LayoutManager no longer ignores some RecyclerView.LayoutParams settings, such as MATCH_PARENT in the scroll
direction.
Note: These lifted restrictions may cause unexpected behavior in your
layouts. Make sure you specify the correct layout
parameters.
Using com.android.support:recyclerview-v7:23.4.0 solves the problem of nested recyclerview not appearing in nested scroll view

Scrollbar not showing in RecyclerView

I've got a RecyclerView and would like to have scrollbar showing, when it covers more than one page.
I get no scrollbar at all. Any idea?
My layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<CheckBox
android:id="#+id/cl_only_empty"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:elevation="5dp"
android:text="#string/cl_only_empty"
android:textColor="#color/white" />
<android.support.v7.widget.RecyclerView
android:id="#+id/callsList"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
</LinearLayout>

The solution is to set the vertical (or horizontal) scrollbar in the xml layout:
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />

Use android:scrollbars attribute "vertical" and android:scrollbarThumbVertical attribute to set the color and android:scrollbarSize attribute to specifiy size:
<android.support.v7.widget.RecyclerView
android:id="#+id/document_listview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="3dp"
android:layout_marginTop="3dp"
android:scrollbars="vertical"
android:scrollbarThumbVertical="#android:color/darker_gray"
android:scrollbarSize="5dp"
android:background="#color/activity_bg"
android:dividerHeight="4dp" />

use recyclerView as below in xml layout
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:scrollbars="vertical"
android:fadeScrollbars="true"
android:layout_width="match_parent"
android:layout_height="match_parent" />
and add below code for scrollview in java, it will be okay
RecyclerView recyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity(), LinearLayoutManager.VERTICAL, false));
recyclerView.setHasFixedSize(true);

I had the same problem on my old HTC Desire X (api 16) only.
I don't know why, but scollbars of RecyclerView doesn't work properly on this device if the android:background property is not set. Try to set it to any color or to transparent - it works for me, hope it helps you too

You can use from :
setScrollbarFadingEnabled(boolean)
Scrollbar Link

Scroller can be set to recyclerview on multiple ways.
1st you can simply add scrollbar in xml and set its property android:fadeScrollbars="false" to always show it.
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerViewMachine"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fadeScrollbars="false"
android:scrollbarThumbVertical="#android:color/darker_gray"
android:scrollbarSize="5dp"
android:scrollbarStyle="outsideOverlay"/>
Or you can make a style theme and use it programitically when initializing recyclerview
<style name="ScrollbarRecyclerView" parent="android:Widget">
<item name="android:scrollbars">vertical</item>
</style>
RecyclerView recyclerView = new RecyclerView(new ContextThemeWrapper(context, R.style.ScrollbarRecyclerView));
thanks

Besides the android:scrollbars attribute, you should add android:fadeScrollbars attribute in false state like this:
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
android:fadeScrollbars="false"/>
This way, the vertical scrollbar is always showing when it's using more height of the layout permitted.

Try this:
mLayoutManager = new LinearLayoutManager (this);
mLayoutManager.setSmoothScrollbarEnabled (true);

If you are fine to set ScrollBar programmatically, then you can use ContextThemeWrapper. First you need to define styling in Style.xml file:
<style name="ScrollbarRecyclerView" parent="android:Widget">
<item name="android:scrollbars">vertical</item>
</style>
And then apply styling when you initialize your RecylerView:
RecyclerView recyclerView = new RecyclerView(new ContextThemeWrapper(context, R.style.ScrollbarRecyclerView));

Add the code to Recycler view xml to make scroll bar visible.
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fadeScrollbars="false"
android:scrollbars="vertical"
android:scrollbarSize="#dimen/_2sdp"
android:scrollbarThumbVertical="#color/white"/>

Actually, it's because of the theme. The scrollbars are there but can't be seen because they blend with the color on the parent view or some other view in the line of its ancestors.
You can create a drawable shape and give it the color you want then set that as the vertical or horizontal scrollbar drawable. That is, if you do not want to mess around with your theme colors.

Using xml android:fadeScrollbars="false"
Using java ScrollView.setScrollbarFadingEnabled(false);
