Is it possible to support Paging concept introduced in recent year?

• [x] I have verified there are no duplicate open or recent questions.
• [x] I have read over the documentation, checked out the examples and the demo app.
• [x] I have given my issue a non-generic title.
• [x] I understand that if I ask the same question in stackoverflow website I will get answers way faster as more people will try to answer it.
• [x] I understand that if I don't show a minimum effort of what I have tried and where I got stuck the question will be closed and marked as invalid.
• [x] I have read the article How do I ask a good question?
• [x] I understand that this library is a custom Adapter and NOT a custom RecyclerView. I understand the difference between them and what is possible to be done in an Adapter but not in a RecyclerView.

I really like the addSection concept provided by this library.

In recent year, Google introduced Paging concept. Instead of having to load entire data from database into memory, then present it in RecyclerView. User can now choose to only load a very small subset of data, during RecyclerView scrolling.

Google achieves so by introducing

• https://developer.android.com/reference/android/arch/paging/PagedListAdapter
• LiveData<PageList<...>> returned by Room DB

The key concept, is to call submitList in PagedListAdapter, whenever the new subset of data is available, during scrolling.

A nice introduction video during Google I/O 2018 is available - https://www.youtube.com/watch?v=BE5bsyGGLf4

Currently, I cannot see a direct way, how we can fit such submitList paging concept, into SectionedRecyclerViewAdapter.

I was wondering, do you have any idea how we can achieve Section concept, yet able to provide paging capability?

Thank you.

After reading https://medium.com/@chibatching/how-to-connect-paging-library-with-groupie-f8b4102d59b0 and look at her example project (She is using a class called Group, which I believe is analogue to Section)

https://github.com/chibatching/paging-retrofit-sample/blob/master/app/src/main/java/com/chibatching/pagedlistgroup/PagedListGroup.java

I believe we can achieve similar effect, by having PagedListSection

I was wondering, whether you are interested to incorporate paging capability into your library? If yes, I'm more than happy, to spend some time to R&D, and provide proper implementation for such capability.

(Note, this may introduce androidx.paging dependency into your library)

Thank you!

Hey @yccheok , happy to have this introduced in the library, but please do any R&D on top of branch 3.0.0 as I'm planning to have a new release soon.

[yccheok]

Thank you @luizgrp I will kick start the R&D when time permits.

@luizgrp Any thing new regarding this feature/request ?

[yccheok]

Sorry. I haven't look into this. This month and next month, I will kick start a new project which requires me to employ paging concept. Hopefully I can learn something new, and provide some useful input to this ticket.

@yccheok Thanks for your reply, I tired to implement it but no luck until now, I also need it in a project too.
