Yes ! Yeeees ! The only approach that finally works for me after 3 months of hard researches and tests and disappointing mistakes !!! 😁I was trying to show firebase data in a RecyclerView of a TabbedView with a Drawer Navigation... But I never could ! Thanks Foxandroid !!!

Thank you for the post, but I have a question. In the case that it is in a fragment and not in an activity it does not work for me. Could you give me some tips?

Parabéns meu amigo. Mesmo entendendo pouco de sua lingua eu consegui fazer tudo e funcionou direitinho. Obrigado pela ajuda. Ganhou um inscrito e um joinha.

The Activity opens up blank where the data is supposed to be retrieved and then goes back to MainActivity or the app crashes. When I check the logcat it says "No Adapter Attached, Skipping Layout".
