firebaseArray descending order?

Question

Using firebaseArray, is it possible to order by a specified child key: (https://www.firebase.com/docs/web/guide/retrieving-data.html#section-queries)?

var fi         


        

Answer 1

This doesn't directly answer the original question, but for anyone using FirebaseUI Java/Android, with a RecyclerView, it's possible to order the RecyclerView in reverse, rather than using a query on Firebase:

Example:

LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
layoutManager.setReverseLayout(true);
layoutManager.setStackFromEnd(true);
recyclerView.setLayoutManager(layoutManager)

(Ensuring you set both before adding the layout manager to the RecyclerView also)
