I am using the android paging library to show a list of posts in the recycler view, my data source loads data from inMemory list which I add and remove from it then invalidate the data source to refresh the PagedListAdapter, everything is working well, but the problem is that when I scroll through pages, for example, page #5, and delete some item and call invalidate(), the data source will be re-initialized and will invoke the callbacks again, which re-loads the items in the recycler view, and jump to the first page. The question is: How to refresh the items without jumping to the first page, and stick in the selected position?

Thanks.

    invalidate will redraw all items in the list, when removing item use notifyItemRemoved() method – Ahmed.ess Nov 30 '18 at 14:31
