Retrieve all data under node in firebase realtime database

Question

I have a firebase realtime database and want to use the data to make a leaderboard. Im trying to retrieve all the data in my Scores node but am not sure how to loop through to g

Answer 1

It appears as though you are using a "Listener" class to access the data and print out the scores. The "ValueEventListener" listener you attached, with the "onDataChange()" method implemented, would not be called until there is a data change.

I'm not sure how you are using this class, but based on your question, I am assuming that you just want to print the scores when the "leaderboard.onCreate()" method is executed. Is this correct? If that is the case, you may not need to be attaching a listener.
