excuse me, I want to ask. After the data is successfully displayed, how do I add a button, and if the button is pressed, it will move and display the same data?

[@ADeviousyoungman]

Speeda thru the xml layout and now i have to find some way to put two linear layouts right beside eachother and not in each other

[@vanessafimer6225]

Thanks Foxandroid for the video. I have 2 questions. 1) Will your solution automatically update the Recyclerview in the UI when a new entry is stored in the Firebase Database? 2) As far as I understand you should not use a database like this in general. You should use a Viewmodel and LiveData. Why are you not using them?

[@_foxandroid]

For updating RecyclerView make sure on datachange callback method is used Yes MVVM architecture should be used..but the intent of the tutorial was to keep it simple so even beginners could understand

Incredibly helpful video! One thing I still need help with, though - how do you re-organize the users by age/score? Basically I want to make a leaderboard that shows the users with the highest scores at the top, but I still want to use the Firebase timestamp-generated children (eg. Users > 2fI5nZavUacjiO6qN4g3yaWRtmg1 > Username: Bob; Score: 100). How would I organize the users based on their score value?

[@_foxandroid]

There are two options you can do that at client side...i have video on that RecyclerView Ascending order....or you can query data in specific order

[@smhily]

@@_foxandroid Awesome! That was actually way simpler than I thought. For anyone else looking for the answer, all you have to do is add this code to the EventListener (line 43) in the userlist Class: Collections.sort(list, new Comparator() { @Override public int compare(User o1, User o2) { return Integer.compare(o1.age, o2.age); } }); I placed it in-between where you check the dataSnapshot values and myAdapter.notifyDataSetChanged(); (approx. line 54), but you could probably add it somewhere else, I'm not sure. It was also necessary to change the age variable in my User object to an Integer - which you then need to convert back to a string before writing it to the text field. As a side-note, I would suggest that developers use a ListenerForSingleValueEvent instead of a ValueEventListener, otherwise the RecylerView will update in real-time which may result in >100 simultaneous connections or data usage in excess of the free 10GB p/m if your app gets big. Hope this helps someone!
