问题 I think I'm doing something wrong but I can't figure which part... Thanks for all the clarification I can get. So I have a collection named Bases that looks like this: { "id1": { "name": "My base 1", "roles": { "idUser_123": { "name": "John" } } }, "id2": { "name": "My base 2", "roles": { "idUser_456": { "name": "Jane" } } } } idUser_123 log in and want to access his collection.

I'm at the point where I made a list and gave it a title, but can't show the places that I planned to go in the activity, here is a screenshot of the activity

问题 I'm new to firebase realtime database, and have a basic question I cannot seem to find the answer to. I need my Android app to keep track of changes in the database, so I understand I need to use addValueEventListener, with the onDataChange method.
