## 前言 ##

本节我们来简单介绍RecyclerView组件，RecyclerView 是 Android 及其重要的一个高级 UI 控件，使用频率及其的高，APP 的 90%以上的页面都会使用的到。由于其出色的性能和插拔式的架构设计，被全世界广大开发者一致称赞。

--------------------

**一、LinerLayoutManager列表布局**

**1、横向列表**

recyclerView.layoutManager =LinearLayoutManager(context, HORIZONTAL,
    false)
    recyclerView.adapter = MyAdapter()

**2、纵向列表**

recyclerView.layoutManager =LinearLayoutManager(context, VERTICAL, false)
    recyclerView.adapter = MyAdapter()

**3、资源适配器**

inner class MyAdapter : RecyclerView.Adapter<ViewHolder>() {
     // 【必须复写】创建 ItemView 的 ViewHolder，用于后续的数据绑定
     override fun onCreateViewHolder(parent: ViewGroup, viewType: Int):
    ViewHolder {
     val view
    =LayoutInflater.from(context).inflate(R.layout.item_view_staggered,
    parent, false) 
     return ViewHolder(view)
     }
     // 【必须复写】告诉 RecyclerView 列表上 item 的条数
     override fun getItemCount(): Int {
     return 20
     }
     // 【必须复写】item 的数据绑定
     override fun onBindViewHolder(holder: ViewHolder, position: Int) {
     
    holder.itemView.item_head.setImageResource(R.drawable.icon_jetpack)
     holder.itemView.item_name.text = "【${position}】移动端架构师体
    系课"
     holder.itemView.item_message.text =
     "移动开发“两极分化”，没有差不多的“中间层,唯有尽早成长为架构师，
    你的职业道路才能走的更远更稳"
     }
     }
     // 创建一个 ViewHolder 必须继承自 RecyclerView.ViewHolder。用于后续的数据
    绑定
    inner class ViewHolder(itemView: View) :
    RecyclerView.ViewHolder(itemView) {
     }

## 二、GridLayoutManager 网格布局 ##
