Recyclerview scroll lagg with android 8

I have implemented a recyclerview in my app. The recyclerview has one view holder that contains a card with all views.
I have experienced the scrolling lagg only on android 8. Same code works as a charm on all previous versions. Please let me know how to fix this lagg because i have tested the same code with many different devises and i have same result.

onBindViewHolder is called only a few times.

I think number of calls to onBindViewHolder is equal to the return value of getItemCount().

In my case, getItemCount() method returns 60. But onBindViewHolder is called only 3 times.

LAYOUT_MANAGER_KEY typo?

RecyclerViewFragment appears to have the wrong variable in the savedInstanceState sections.
It refers to "LAYOUT_MANAGER_KEY", I'm assuming is should be changed to "KEY_LAYOUT_MANAGER".
I've submitted a pull request.
Thanks for all the tasty samples!

build.gradle is empty

why build.gradle is empty?

Example missing most common usecase for lists: Selecting an item

The viewholder pattern is nice and helpful for performance and so on but my guess would be that in 99% of cases when we are using a RecyclerView (no matter what layoutmanager) what we want isn't just to display items but to be able to select an item.

And seeing as this seems to be the only sample of how to use RecyclerView:
Please add some sort of implementation of an item click handler to this sample.

When datas is empty, i add first data.but not use notifyDataSetChanged, then use notifyItemInserted(0) 。then error is happen
