Kotlin_和RecyclerView的一个demo

Kotlin请求网络拿到数据后用RecyclerView显示的一个demo

这是请求网络拿到数据的Demo

本篇主要接上篇拿到数据后的展示

一:拿到数据后给recycler设置布局管理器和adapter

 recyclerview.layoutManager = LinearLayoutManager(applicationContext)
 recyclerview.adapter = MyAdapter(response.body())

二:Adapter代码

(R.layout.item_case只有一个TextView)

  class MyAdapter(var context: Context,var listBean: CaseListBean) : RecyclerView.Adapter() {

        override fun onBindViewHolder(holder: ViewHolder, position: Int) {
            holder.tvTitle.text = listBean.data!!.data!![position].case_name
            //点击事件
            holder.tvTitle.setOnClickListener {
                Toast.makeText(context,holder.tvTitle.text,Toast.LENGTH_SHORT).show()
            }
        }

        override fun getItemCount(): Int {
            return listBean.data!!.data!!.size
        }

        override fun onCreateViewHolder(parent: ViewGroup?, viewType: Int): ViewHolder {
            val view = LayoutInflater.from(parent?.context).inflate(R.layout.item_case, parent, false)
            return ViewHolder(view)
        }

        class ViewHolder : RecyclerView.ViewHolder {

            var tvTitle: TextView

            constructor(itemView: View) : super(itemView) {
                tvTitle = itemView.findViewById(R.id.tv_1)
            }
        }

    }
