how to define viewTypes with conditions

[MahmoudMabrok]

now we can register viewTypes but README has no way to determine which viewType is created at spefici position i.e
how to make views has two types Head, Sub

• Head with odd positions
• Sub with even positions

Hi @MahmoudMabrok,

Thank you for your question.

You specify this while you are defining your RecyclerViewHolder<T>.

You need to define HeadRecyclerViewHolder and SubRecyclerViewHolderfor your Head and Sub.

In the list, which you provide the adapter, you should do that mapping.

val list = listOf("abc", "xyz", "qwe", ...)

...
// mapper
val dataSource = list.mapIndexed{index, item ->
           if (index ÷ 2 == 0) Head(item) else Sub(item) 
}

adapter.submitList(dataSource)

In that way, you can test your mapper.

I hope everything is clear now.

Sincerely
Ibrahim

it will more better if it added with register function

[ibrahimyilmaz]

Do you mean putting type in the register function?

[MahmoudMabrok]

yes,or a way to determine type
add function like register but it return viewType
and with register we can select which type

i think it need brain storm to get right design

Actually type is coming by RecyclerViewHolder. As it is reified Kiel could understand which type it is.

I appreciate your support. Any syntax alternatives are welcome.
also you may consider putting new syntax alternative under this issue #34.
