安卓开发 原生View 垂直recyclerview 嵌套水平recyclerview 帮我写完整kotlin 代码

好的，以下是一个垂直 RecyclerView 嵌套水平 RecyclerView 的 Kotlin 代码示例：

class MainActivity : AppCompatActivity() {
    private lateinit var verticalRecyclerView: RecyclerView
    
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        
        // 初始化垂直 RecyclerView
        verticalRecyclerView = findViewById(R.id.verticalRecyclerView)
        verticalRecyclerView.layoutManager = LinearLayoutManager(this, RecyclerView.VERTICAL, false)
        val verticalAdapter = VerticalAdapter()
        verticalRecyclerView.adapter = verticalAdapter
        
        // 设置垂直 RecyclerView 的数据源
        val verticalDataList = mutableListOf<VerticalItem>()
        verticalDataList.add(VerticalItem("Item 1"))
        verticalDataList.add(VerticalItem("Item 2"))
        verticalDataList.add(VerticalItem("Item 3"))
        verticalAdapter.setData(verticalDataList)
    }
    
    // 垂直 RecyclerView 的适配器
    inner class VerticalAdapter : RecyclerView.Adapter<VerticalAdapter.VerticalViewHolder>() {
        private var dataList = mutableListOf<VerticalItem>()
        
        fun setData(dataList: List<VerticalItem>) {
            this.dataList.clear()
            this.dataList.addAll(dataList)
            notifyDataSetChanged()
        }
        
        override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): VerticalViewHolder {
            val view = LayoutInflater.from(parent.context).inflate(R.layout.item_vertical, parent, false)
            return VerticalViewHolder(view)
        }
        
        override fun onBindViewHolder(holder: VerticalViewHolder, position: Int) {
            val verticalItem = dataList[position]
            holder.titleTextView.text = verticalItem.title
            
            // 初始化水平 RecyclerView
            val horizontalLayoutManager = LinearLayoutManager(holder.itemView.context, RecyclerView.HORIZONTAL, false)
            holder.horizontalRecyclerView.layoutManager = horizontalLayoutManager
            val horizontalAdapter = HorizontalAdapter()
            holder.horizontalRecyclerView.adapter = horizontalAdapter
            
            // 设置水平 RecyclerView 的数据源
            val horizontalDataList = mutableListOf<HorizontalItem>()
            horizontalDataList.add(HorizontalItem("Subitem 1"))
            horizontalDataList.add(HorizontalItem("Subitem 2"))
            horizontalDataList.add(HorizontalItem("Subitem 3"))
            horizontalAdapter.setData(horizontalDataList)
        }
        
        override fun getItemCount(): Int {
            return dataList.size
        }
        
        inner class VerticalViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
            val titleTextView: TextView = itemView.findViewById(R.id.titleTextView)
            val horizontalRecyclerView: RecyclerView = itemView.findViewById(R.id.horizontalRecyclerView)
        }
    }
    
    // 水平 RecyclerView 的适配器
    inner class HorizontalAdapter : RecyclerView.Adapter<HorizontalAdapter.HorizontalViewHolder>() {
        private var dataList = mutableListOf<HorizontalItem>()
        
        fun setData(dataList: List<HorizontalItem>) {
            this.dataList.clear()
            this.dataList.addAll(dataList)
            notifyDataSetChanged()
        }
        
        override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): HorizontalViewHolder {
            val view = LayoutInflater.from(parent.context).inflate(R.layout.item_horizontal, parent, false)
            return HorizontalViewHolder(view)
        }
        
        override fun onBindViewHolder(holder: HorizontalViewHolder, position: Int) {
            val horizontalItem = dataList[position]
            holder.titleTextView.text = horizontalItem.title
        }
        
        override fun getItemCount(): Int {
            return dataList.size
        }
        
        inner class HorizontalViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
            val titleTextView: TextView = itemView.findViewById(R.id.titleTextView)
        }
    }
}

// 数据类
data class VerticalItem(val title: String)
data class HorizontalItem(val title: String)

其中，垂直 RecyclerView 使用 `VerticalAdapter` 作为适配器，水平 RecyclerView 使用 `HorizontalAdapter` 作为适配器，分别用两个数据类 `VerticalItem` 和 `HorizontalItem` 表示它们的数据项。这个示例代码仅供参考，具体实现还需要根据项目需求进行调整。
