dataSnapshot has the object but getValue() will return null

Question

So I\'m struggling with this issue for about three hours now.
I have this user class

public class User {
private String user_id;
private String userNa         


        

Answer 1

You need to iterate over dataSnapshot.getChildren(...for example

                for (DataSnapshot childSnapshot: dataSnapshot.getChildren()) {
                    User user = childSnapshot.getValue(User.class);
                 }
