如何在Kotlin中显示RecyclerView为空的其他视图？

// 布局文件中的定义
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

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

    <TextView
        android:id="@+id/emptyView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="No data available"
        android:visibility="gone" />

</LinearLayout>

// 自定义适配器类
class MyAdapter(private val dataList: List<String>) : RecyclerView.Adapter<MyAdapter.ViewHolder>() {

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

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

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

    inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
        fun bind(data: String) {
            // 绑定数据到视图上
        }
    }
}

// Activity或Fragment中的代码
val recyclerView: RecyclerView = findViewById(R.id.recyclerView)
val emptyView: TextView = findViewById(R.id.emptyView)

val dataList: List<String> = // 获取数据集合

if (dataList.isEmpty()) {
    recyclerView.visibility = View.GONE
    emptyView.visibility = View.VISIBLE
} else {
    recyclerView.visibility = View.VISIBLE
    emptyView.visibility = View.GONE

    val adapter = MyAdapter(dataList)
    recyclerView.layoutManager = LinearLayoutManager(this)
    recyclerView.adapter = adapter
}
