RecyclerView inside NestedScrollView onBindViewHolder calling for all getItemCount size

Question

When I put RecyclerView inside NestedScrollView then onBindViewHolder is calling for all row like say I have list which has size of 30

Answer 1

I'm going to assume that since your are using appbar_scrolling_view_behavior you are trying to do something with AppBarLayout.

If so, you can use RecyclerView as a direct child of CoordinatorLayout and have support for AppBarLayout scrolling without nesting RecyclerView inside of NestedScrollView.

Try this: RecyclerView inside CoordinatorLayout (with AppBarLayout and CollapsingToolbarLayout):

And in your Activity or CustomView:

RecyclerView list;
LinearLayoutManager layoutManager = new LinearLayoutManager(getContext());
list.setLayoutManager(layoutManager);
list.addItemDecoration(new VerticalSpaceItemDecoration(5));
list.setAdapter(adapter);
