Is there any way I can fetch 50 items a time and then fetch next 50 and on-wards?

Question

I am fetching 1000 items from server at a time and displaying it in Recycler view. Is there any way I can fetch 50 items a time from server and then fetch next 50 from server and then on-wards from server as well? If not possible, then how can I display only 50 item in recycler view at first and then respective on load more button click?

Yes, it is possible. it's called "Pagination of data", you can use `OnScrollListener` for `RecyclerView` and load more data from there. — Jeel Vankhede, Oct 16 '18 at 09:55
use google's [paging](https://developer.android.com/topic/libraries/architecture/paging.html) support library - do not use any custom `OnScrollListener`s — pskink, Oct 16 '18 at 09:57

Api should build in a way that it can process according LIMIT and OFFSET

server side query will be like.... SELECT contact_id, last_name, first_name FROM contacts ORDER BY contact_id DESC LIMIT 5 OFFSET 2;

than you can hit api onScrollListener at end index, getting 1000 data may slow down the app – kuber singh Oct 16 '18 at 09:57
