firebase - firebaseArray descending order? -

using firebasearray, possible order specified child key: (https://www.firebase.com/docs/web/guide/retrieving-data.html#section-queries)?

var fireref = new firebase(https://dinosaur-facts.firebaseio.com/dinosaurs); var query = fireref.orderbychild("echo").limittofirst(25); var todos = $firebasearray(query); 

however, default, firebase retrieves keys in ascending order.

children numeric value come next, sorted in ascending order.

is there way results in descending order directly firebasearray? example, have .reverse() or .orderby(desc, ...)?

this doesn't directly answer original question, using firebaseui java/android, recyclerview, it's possible order recycler view in reverse, rather using query on firebase:

example:

linearlayoutmanager layoutmanager = new linearlayoutmanager(getactivity()); layoutmanager.setreverselayout(true); layoutmanager.setstackfromend(true); recyclerview.setlayoutmanager(layoutmanager) 

(ensuring set both before adding layout manager recycler view also)
