回答1:

From what i understand by your question and log is basically you are clearing the arraylist in onRefresh() but not notifying the adapter that the list has been cleared.

Please call notifyDataSetChanged() after clearing arraylist

回答2:

Seems like you have cleared your list upon refresh, but the items are still in your recyclerview. You should notify your adapter that the list is empty now. In your current situation, starting to scroll will probably cause the application to crash as well?!

回答3:

you should put condition for check the size of (for eg. array, ArrayList ... used by you ) data
