将项目添加到现有的 AlertDialog

Adding items to an existing AlertDialog

所以我需要显示一个带有一个项目的AlertDialog,然后执行一个get请求,在它解决之后,我需要向对话框添加更多项目。

我尝试了下面的代码但没有成功

var list = arrayOf("aa")
val b = AlertDialog.Builder(context)
b.setItems(list, onItemClickListener)
val dialog = b.create()

executeGetRequest() {
   list += "New Item"
   val adapter = dialog.listView.adapter as ArrayAdapter<*>
   adapter.notifyDataSetChanged()
}

但是,正在更新现有项目:

list[0] = "Updated Item"
adapter.notifyDataSetChanged()

我错过了什么?

已解决

val list = arrayListOf("aa")
val b = AlertDialog.Builder(context)
val onItemClickListener = DialogInterface.OnClickListener { dialog, which ->
    // code
}
val adapter = ArrayAdapter(requireContext(), 
    android.R.layout.simple_list_item_1, list)
setAdapter(adapter, onItemClickListener)

executeGetRequest() {
   list.add("New Item")
   adapter.notifyDataSetChanged()
}
b.show()
