android - Find out if childEventListener on Firebase has completed loading all data

Question

I'm using Firebase Realtime Database for storing and retrieving data for my Android application. In my activity I retrieve all data (example: list of user data) from Firebase using a childEventListener.

I want to show a progress bar as long as the data is not completely retrieved from the database. How do I check if all data is completely retrieved so that I can close the progress bar after the data is loaded?
