ok, is there any easy way of it . actually I have five different Lists with search functionality so therefore I want to abstract Search logic in base Adapter then extend Other five adapters from Base adapter, please help how can I achieve this

And why do you need generic variance for this?

as I mentioned I need I'm creating Base functionality for search for recycler view that's by I'm using genrics

I still don't really get what you want 😞

Spose u have 10 Different RecyclerView adapters each having Search functionality (filters list according SearchView) then how do you deal with with Duplication of code,do you write filtering logic in each Adapter ?
