What? It is not a custom TabLayout
or RecyclerView
. It is just a helper library to attach to your RecyclerView
with your TabLayout
. If you don't want to go with sticky header RecyclerView
or something like that, and also want to provide a good experience when your user is scrolling the content, this small library is for you.

How? You fetch your product list and their categories. All you need to do is calcualate start index for all categories. Attacher will do the rest.
If your backend guy returns this json,
CategoryA -> 10 items (between 0..10)
CategoryB -> 20 items (between 10..30)
CategoryC -> 30 items (between 30..60)
Then your offset list will be,
//3 tabs and their offset indexes in total list.
val categoryIndexOffsetList = [0,10,30]
๐
Then? Then you attach.
val attacher = TabScrollAttacher(tabLayout, recyclerView, categoryIndexOffsetList)
attacher.attach()
Detach when you don't need anymore.
attacher.detach()

Configure? scrollDirectly()
: If you don't want to see the scrolling process, use it.scrollSmoothly()
: If you want to see the flowing items while scrolling, this is for you.scrollSmoothly(limit = 10)
: If you have a lot of items and smooth scrolling takes too long, you can set a scrolling item limit. It will scroll directly until thelimit
items left, then rest of the items will scroll smoothly.
TabScrollAttacher(tabLayout, recyclerView, categoryIndexOffsetList) {
// Configuration
}
