Thanks for the update - I am planning on looking into this for 3.1, but have a few other higher priorities at the moment, sorry for the wait!

I have the same problem as well, using withLoadStateHeaderAndFooter.

Did anyone figure out some workarounds?

I tried overriding LinearLayoutManager's canScrollVertically to false until data is loaded, but somehow it has no effect, recyler kind of "appears" at the bottom and I can't seem to stop it.

The only scroll event that gets emitted is onScrolled: dx=0 dy=0. I don't have any outer scrolling containers.

This is actually RecyclerView getting confused because it does not know that your loading item is not a real "less priority" item.

I added a workaround here: https://buganizer.corp.google.com/issues/186560106#comment5

meanwhile, we should still try to figure out a solution for this but that might require an explicit RecyclerView API change, so might take a while.

With 3.1 and the workaround mentioned in #7, the problem with the initial page scrolling a little bit appears to be sufficiently worked around. However, subsequent pages exhibit a strange insertion animation if the recycler view is scrolled quickly enough to see the progress bar. It only happens when the progress bar is shown and it happens directly after its hidden. I suspect this is still related to the concat adapter and the priority problem mentioned in #7. I attached a gif of the behavior. There was one fling in the gif. The second animation/shift happens on its own.

For those interested, the ticket to track the required change in RecyclerView is here: b/204123767

Hi there, could you share the workaround mention in #7 in this post? cause i could not login this the website
