How to clear/remove all items in page list adapter

Question

I\'m using the android paging library to show search result items, is there any way I can clear/remove all the loaded result items, Calling Invalidate on live Paged List refresh

Answer 1

In Java:

I cleared all items on in PagedListAdapter by calling invalidate() on DataSource instance like that

public void clear(){
   movieDataSource.invalidate();
}

Add this method in your ViewModel then call it in your activity

movieViewModel.clear();
movieAdapter.notifyDataSetChanged();

Then Load any data you want

You can see how I made it in my project.
