保存recyclerview列表的状态

Question

I created a list using recyclerview in one activity. The user dynamically removes some of the items he/she doesn't from the list so the problem arises when he navigates back to that activity. The activity retrieves all the data items,including the ones he removed. How do i make sure the recyclerview list retains the state the user left it in?

Answer 1

The problem is in List you are using. You need to use Activity's list reference in Adapter too, Don't create different list in adapter just save Activity's list reference in Adapter.
