How to display data from firebase in android studio?

Question

Java

I don’t understand how to work with firebase, I’ve only been working with android for 2 days, I still haven’t really figured out anything.
it is necessary that instead of [email protected] the surname, first name and patronymic should be written, and below mail, all this is from the firebase database
how to display data so that the text from the database is written in the TextView, can you describe in detail?
and where to write the code, in MainActivity.java?

Answer 1

You can find ready-made open source examples by keywords: firebase example github and dig into them, it will be faster than trying to delve into it on your own. Or, as an alternative, try Flutter, because. it's simpler than Java/Kotlin and there are already ready -made firebase examples with code (advanced tab at the bottom of the screen).
