Attach Tab Layout and Recycler View Useful for categorizing Recycler View items

TabScrollAttacher

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]

Then?

Then you attach.

TabScrollAttacher(tabLayout, recyclerView, categoryIndexOffsetList)
