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    lt ScrollView  gt      lt LinearLayout  gt           lt View  gt   lt  -- upper content -- gt          lt RecyclerView  gt   lt  -- with custom layoutmanager -- gt       lt  LinearLayout  gt   lt  ScrollView  gt    You can modify that to    lt CoordinatorLayout  gt        lt AppBarLayout  gt           lt CollapsingToolbarLayout  gt                lt  -- with your content  and layout scrollFlags  scroll  -- gt           lt  CollapsingToolbarLayout  gt       lt  AppBarLayout  gt        lt RecyclerView  gt   lt  -- with standard layoutManager -- gt    lt  CoordinatorLayout  gt    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    lt ScrollView  gt      lt LinearLayout  gt           lt View  gt   lt  -- upper content -- gt          lt RecyclerView  gt   lt  -- with wrap content -- gt       lt  LinearLayout  gt   lt  ScrollView  gt

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

I only needed to use this   mMyRecyclerView setNestedScrollingEnabled false     in my onCreateView   method   Thanks a lot

Every answer is same here  and i already used what everyone is suggested  Then i found that NestedScrollView is faster then ScrollView so use  lt androidx core widget NestedScrollView  Instead of  lt ScrollView  And use this as usual recycleView setNestedScrollingEnabled false

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

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    lt 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    gt     Programmatically    recycleView    RecyclerView  findViewById R id recycleView    recycleView setNestedScrollingEnabled false

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

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    lt android support v4 widget NestedScrollView         android layout width  match parent          android layout height  match parent  gt            lt android support v7 widget RecyclerView             android layout width  match parent              android nestedScrollingEnabled  false              android layout height  wrap content              android clipToPadding  false    gt    lt  android support v4 widget NestedScrollView gt    Thanks Micro this was from your hint   karthik
