如何在Kotlin的对话框中设置autoCompleteTextView？我从firebase获取数据，并用它来填充自动补全建议

<AutoCompleteTextView
    android:id="@+id/autoCompleteTextView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="输入关键字"
    android:completionThreshold="1" />

val dialogView = LayoutInflater.from(context).inflate(R.layout.dialog_layout, null)
val autoCompleteTextView = dialogView.findViewById<AutoCompleteTextView>(R.id.autoCompleteTextView)

// 获取Firebase数据，并将其转换为适配器所需的数据格式
val firebaseDataList: List<String> = // 从Firebase获取数据

val adapter = ArrayAdapter(context, android.R.layout.simple_dropdown_item_1line, firebaseDataList)
autoCompleteTextView.setAdapter(adapter)

// 设置自动补全建议的点击监听器
autoCompleteTextView.setOnItemClickListener { parent, view, position, id ->
    val selectedItem = parent.getItemAtPosition(position) as String
    // 处理选中的自动补全建议项
}

// 设置自动补全建议的过滤器
autoCompleteTextView.addTextChangedListener(object : TextWatcher {
    override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {}

    override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {}

    override fun afterTextChanged(s: Editable?) {
        adapter.filter.filter(s)
    }
})

// 创建对话框并设置布局
val dialogBuilder = AlertDialog.Builder(context)
dialogBuilder.setView(dialogView)
dialogBuilder.setPositiveButton("确定", null)
dialogBuilder.setNegativeButton("取消", null)

val dialog = dialogBuilder.create()
dialog.show()
