[mbfakourii]

Hello when i use the invalidate() and RecyclerView is on the page for example 7 then the invalidate() is scrolled to page 2

 sourceFactory.usersDataSourceLiveData.value!!.invalidate()

i got this issue too. Have you fixed this issue?

[mbfakourii]

No, I haven't got anything yet but I realized this is a problem on the part of Google

I think so. I tried to get the key from adapter.currentList.lastKey but always return null. I am trying another ways.

Are you using PagedKeyedDataSource or ItemKeyedDataSource?

[mbfakourii]

No, I didn't use it!
Did you solve the problem?

I solved use some hacky solution :)
So, whenever I observed the network state, I scroll the recyclerview to top if the swipe refresh is in refreshing state. Here is the snippet:

yourViewModel.getNetworkState().observe(
            viewLifecycleOwner,
            androidx.lifecycle.Observer<NetworkState> {
                    if (bd.swipeRefreshLayout.isRefreshing)
                        bd.historyRV.smoothScrollToPosition(0)
                    bd.swipeRefreshLayout.isRefreshing = false
})

Please share if you have better solution.

I don't think it's a good way

This solution is for temporary. Can you provide cleaner solution?
