问题 I have a ListFragment that has a recyclerview and onClick on any items opens the DetailsFragment. The details fragment contains another recyclerview on the bottom that shows "MORE ITEMS". Now onClick on any of these items should open the DetailsFragment for that particular item. Basically the fragment needs to be refreshed. In the past, I would just replace fragment using fragmentManager. How do I go about refreshing the fragment? How can I create an action that points to the same fragment?

问题 I'm currently looking into incorporating the Paging Architecture library (version 2.1.0-beta01 at the time of writing) into my app. One components is a list which allows the user to delete individual items from it. This list is network-only and caching localy with Room does not make sense. PagedList is immutable and does not support modification. I have read that having a copy of the list which is than modified and returned as the new one is the way to go. The documentation states the same:

问题 I have two graphs, so the first graph move from one fragment to an activity passing safeArgs to the activity. val action = MyFragmentDirections.actionMyActivity(arg1, arg2) Navigation.findNavController(view).navigate(action) Now in the second, I want to pass these arguments from MyActivity to a fragment which belongs to this activity.
