Android Recycleview多个ViewTypes在kotlin中不起作用

class MyAdapter(private val dataList: List<Any>) : RecyclerView.Adapter<RecyclerView.ViewHolder>() {

    // 定义不同的ViewType
    private val VIEW_TYPE_ONE = 1
    private val VIEW_TYPE_TWO = 2

    // 创建ViewHolder
    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): RecyclerView.ViewHolder {
        return when (viewType) {
            VIEW_TYPE_ONE -> {
                val view = LayoutInflater.from(parent.context).inflate(R.layout.item_type_one, parent, false)
                TypeOneViewHolder(view)
            }
            VIEW_TYPE_TWO -> {
                val view = LayoutInflater.from(parent.context).inflate(R.layout.item_type_two, parent, false)
                TypeTwoViewHolder(view)
            }
            else -> throw IllegalArgumentException("Invalid view type")
        }
    }

    // 返回每个item的ViewType
    override fun getItemViewType(position: Int): Int {
        return when (dataList[position]) {
            is TypeOneData -> VIEW_TYPE_ONE
            is TypeTwoData -> VIEW_TYPE_TWO
            else -> throw IllegalArgumentException("Invalid data type")
        }
    }

    // 绑定数据到ViewHolder
    override fun onBindViewHolder(holder: RecyclerView.ViewHolder, position: Int) {
        when (holder) {
            is TypeOneViewHolder -> {
                val data = dataList[position] as TypeOneData
                holder.bindData(data)
            }
            is TypeTwoViewHolder -> {
                val data = dataList[position] as TypeTwoData
                holder.bindData(data)
            }
        }
    }

    // 返回item数量
    override fun getItemCount(): Int {
        return dataList.size
    }

    // 定义ViewHolder类
    inner class TypeOneViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        fun bindData(data: TypeOneData) {
            // 绑定数据到布局中的控件
        }
    }

    inner class TypeTwoViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        fun bindData(data: TypeTwoData) {
            // 绑定数据到布局中的控件
        }
    }
}

// 定义数据类
data class TypeOneData(val text: String)
data class TypeTwoData(val image: Int)
