如何在Kotlin中向下滚动一定数量后显示"Toast“

implementation 'androidx.recyclerview:recyclerview:1.2.1'

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

val recyclerView = findViewById<RecyclerView>(R.id.recyclerView)
val layoutManager = LinearLayoutManager(this)
recyclerView.layoutManager = layoutManager

// 创建一个列表，用于存储数据
val data = mutableListOf<String>()
// 添加一些示例数据
for (i in 1..100) {
    data.add("Item $i")
}

val adapter = MyAdapter(data)
recyclerView.adapter = adapter

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

    class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView)

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
        val view = LayoutInflater.from(parent.context).inflate(android.R.layout.simple_list_item_1, parent, false)
        return ViewHolder(view)
    }

    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        val item = data[position]
        holder.itemView.findViewById<TextView>(android.R.id.text1).text = item

        // 当滚动到指定位置时，显示Toast
        if (position == 10) {
            Toast.makeText(holder.itemView.context, "Toast", Toast.LENGTH_SHORT).show()
        }
    }

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