DEPRECATED

I created this library back in the day when I thought RecyclerView was all new and difficult. Writing an adapter that could inflate multiple types of Views seemed like a difficult job to do. In reality, RecyclerViewHeader is just a complex solution to a simple problem. Instead of using this library, just learn how to create a multi-type RecyclerView.Adapter. It will bring you a lot of value in the long run, and it is not difficult at all. Check the Migration section for the simplest example of such Adapter.

No new development will be taking place.

Thanks for all the support!

If you still wanna use this library, check the old README.md.

Migration

Just use a RecyclerView.Adapter that can inflate multiple types of items.

Here's the simplest one you could use:

class ExampleAdapter : RecyclerView.Adapter<RecyclerView.ViewHolder>() {

    companion object {
        private const val VIEW_TYPE_HEADER = 4815
        private const val VIEW_TYPE_ITEM = 1623
    }

    private val itemDataSetSize: Int get() = TODO("provide the size of your `ITEM` dataset")

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
        when (viewType) {
            VIEW_TYPE_HEADER -> TODO("create your HEADER ViewHolder")
            VIEW_TYPE_ITEM -> TODO("create your ITEM ViewHolder")
            else -> error("Unhandled viewType=$viewType")
        }
    }

    override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
        when (val viewType = getItemViewType(position)) {
            VIEW_TYPE_HEADER -> TODO("bind your HEADER ViewHolder")
            VIEW_TYPE_ITEM -> TODO("bind your ITEM ViewHolder")
            else -> error("Unhandled viewType=$viewType")
        }
    }

    override fun getItemCount(): Int = itemDataSetSize + 1 // 1 for header

    override fun getItemViewType(position: Int) = when (position) {
        0 -> VIEW_TYPE_HEADER
        else -> VIEW_TYPE_ITEM
    }
}
