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!
RecyclerViewHeader
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
}
}

原文： http://blog.csdn.net/qibin0506/article/details/49716795 添加header的思路就是通过adapter的itemType来加载不同的布局。 又根据LayoutManager有不同的处理方式。 1、线性布局LinearLayoutManager 简单，只需要根据不同的itemType处理不同的ViewHolder就能实现。 设置布局管理器

首先看下自己的RecyclerView是否包裹在 LinearLayout, FrameLayout, RelativeLayout.这三种布局中，否则会报错： Currently, NOT already aligned RecyclerViewHeader can only be used for RecyclerView with a parent of one of types: Lin
