SmoothAppBarLayout works only with RecyclerViews

[Jhuku]

I see that SmoothAppBarLayout works only with recycler views. Why cant it be made more generic so that it works with any view.

Hi @Jhuku

It works with RecyclerView and NestedScrollView. It also works with other PullDownToRefresh as well.

What scroll view do you want to use with AppBarLayout beside RecyclerView and NestedScrollView?

[Jhuku]

I tried with nested scroll view. It doesn't work. I used app:sabl_target_id="@/nestedScroll" attribute inside SmoothAppBarLayout.

Can you post your layout here?

Hi @Jhuku

Please do following steps:

• Remove app:layout_behavior="@string/appbar_scrolling_view_behavior" in your NestedScrollView. => Do not use layout_behavior with SmoothAppBarLayout.
• Remove app:sabl_target_id="@id/nest" => This is unnecessary in this layout.

I hope it helps.
