Android Kotlin回收视图reloadData

val dataList: MutableList<String> = mutableListOf()

class MyAdapter(private val data: List<String>) : RecyclerView.Adapter<MyAdapter.MyViewHolder>() {

    // 创建视图持有者
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
        val view = LayoutInflater.from(parent.context).inflate(R.layout.item_layout, parent, false)
        return MyViewHolder(view)
    }

    // 绑定数据到视图
    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        val item = data[position]
        holder.bind(item)
    }

    // 返回数据项数量
    override fun getItemCount(): Int {
        return data.size
    }

    // 定义视图持有者
    class MyViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        fun bind(item: String) {
            // 绑定数据到视图上的各个控件
        }
    }
}

val recyclerView: RecyclerView = findViewById(R.id.recyclerView)
val adapter = MyAdapter(dataList)
recyclerView.layoutManager = LinearLayoutManager(this)
recyclerView.adapter = adapter

dataList.clear()
dataList.addAll(newDataList)
adapter.notifyDataSetChanged()
