android - Recyclerview inside linearlayout scrolling smoothly -

-

i working on screen has 1 tool bar information of product , list of similar products.

<relativelayout> <toolbar /> <scrollbar>     <linearlayout>         <productinfo />         <textview > <!--similar products -->         <recyclerview />     </linearlayout> </scrollbar>

everything working fine except scroll. scroll not smooth when recyclerview comes on screen. think idea should have recycler view without own scrollbar. because seems i'm ending 2 scrollbars making scrolling painful. there way through can disable scrollbar of recyclerview , stretch to occupy required height , parent scrollbar scroll screen smoothly?

i'm using staggeredgridlayoutmanager can use both productinfo view , similar products card in single recyclerview, productinfo need complete width of screen similar product need 2 column. please code:

</scrollview>

for smooth scrolling should use <scrollview> instead of <scrollbar>.
