There’s good documentation on how to do firebase queries as well as apply them to ranges.
Something like:
FirebaseDatabase database = FirebaseDatabase.getInstance(); DatabaseReference ref = database.getReference("table"); Query query = ref.orderByChild("price").startAt(min).endAt(max);
Then you add the appropriate listener for what you are trying to do. (e.g. a ValueEventListener
or a ChildEventListener
via addValueEventListener
or addChildEventListener
respectively.
