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 !!!
Excellent series I really appreciate your tutorials keep up the good work
Thanks... means a lot ❤️
The most awaited video... Thanks bhaiya
I wasted at least two weeks to find solution how to add existing SQLLite database to my project and finaly instead of SQL I added my databse from Firebase whis is much more easier and faster. Thank you for this video. Good job!
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?
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".
did you get the solution
@@codewinger9915 no help

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.
I just did everything what you showed
but showing this error message
E/RecyclerView: No adapter attached; skipping layout
and my app going back to main activity
I had an Error in line:
var dataItem = itemSnapshot.getValue(item::class.java)
itemArrayList.add(dataItem!!)
Failed to convert value of type java.lang.Long to String
Here is my solution:
var age = userSnapshot.child("age").value.toString()
userArrayList.add(User(age))
Hey I am having an issue where the data is not read too my recycle view am doing everything you are doing but I cant get the data to pass

Yes put a button in Mainactivity to go to this activity or make this activity as launcher activity

Hi I am getting a continuous blank screen! Any help would be appreciated! I get an error saying: “E/Recyclerview: No adapter attached; skipping layout” and it seems that the valueEventListener is not firing
There must be some mistake in the code!! Please rewatch and try to find the mistake
@@_foxandroid Hi I have followed your tutorial perfectly but it in getUserData, it doesn't run past Firebase.getInstance line. After doing that it doesn't do addValueEventListener. Could it be due to me not having an import? Or something else?
Please share the issue on Instagram

This video might help please check it out
@@_foxandroid very good guy, still interpreting how it works, because I don't understand english, but I wanted to know that as a video you already have a call from each position, because I put set click to go to another activity so how do you leave this activity with data for guy position?
if you can’t understand very well don’t blame translater kkk
Do you mean to send data to the next Activity??
wow not even your source code works!
good that i tried that tutorial for 3hours!
true 💯 showing No adapter attached
