How to make a list with data loaded when scrolling?

Question

Android

Good day.
I found a lot of information on this issue, so I got confused. My version turned out like this: 1) RecyclerView doesn't care about the size of the list, that's why it's "standard", it's just that new entries are added to the adapter; 2) in the currentCategory adapter has a position, if position == the size of the current list, I make a new request
Now the questions are:
1) are my reasoning correct or is there some big problem that can be solved by answering question
2 2) how to do it right?
If it is important, I get the data through the callback of my class, which, in turn, receives either from the Internet or from the database.

Answer 1

That's right. As soon as you scroll to the end of the list, make a new request. And it would be nice to display progress to the user.
