Display posts in descending posted order

Question

I\'m trying to test out Firebase to allow users to post comments using push. I want to display the data I retrieve with the following;

fbl.child         


        

Answer 1

You can add a column named orderColumn where you save time as

Long refrenceTime = "large future time"; Long currentTime = "currentTime"; Long order = refrenceTime - currentTime;

now save Long order in column named orderColumn and when you retrieve data as orderBy(orderColumn) you will get what you need.
