如何使用hashmap迭代键值对并在kotlin的recycleView中显示？

val hashMap = HashMap<String, String>()
hashMap["key1"] = "value1"
hashMap["key2"] = "value2"
hashMap["key3"] = "value3"

data class KeyValue(val key: String, val value: String)

class KeyValueAdapter(private val data: List<KeyValue>) : RecyclerView.Adapter<KeyValueAdapter.ViewHolder>() {

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

    override fun onBindViewHolder(holder: ViewHolder, position: Int) {
        val keyValue = data[position]
        holder.bind(keyValue)
    }

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

    inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        fun bind(keyValue: KeyValue) {
            itemView.keyTextView.text = keyValue.key
            itemView.valueTextView.text = keyValue.value
        }
    }
}

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

val recyclerView: RecyclerView = findViewById(R.id.recyclerView)
val hashMap = HashMap<String, String>()
hashMap["key1"] = "value1"
hashMap["key2"] = "value2"
hashMap["key3"] = "value3"

val keyValueList = ArrayList<KeyValue>()
for ((key, value) in hashMap) {
    keyValueList.add(KeyValue(key, value))
}

val adapter = KeyValueAdapter(keyValueList)
recyclerView.adapter = adapter
recyclerView.layoutManager = LinearLayoutManager(this)
