【问题描述】：

我想在 Android 警报对话框中显示 Listview。

请任何人帮助我

  void SetDialog(IList<OrderInfo> orders, string contactGuid){

        var dialogView = this.BindingInflate(Resource.Layout.guest_name_list, null);

        var dialog = new AlertDialog.Builder(this.Context);
        dialog.SetView(dialogView);
        dialog.SetNegativeButton("Cancel", (s, a) => { });
        AlertDialog alertDialog = dialog.Create();
        alertDialog.Show();

        dialogView.FindViewById<TextView>(Resource.Id.AlertTitle).SetText(PartyDetailsViewModel.EditAddOrderActionTitle, null);
        dialogView.FindViewById<TextView>(Resource.Id.AlertTitleMessage).SetText(PartyDetailsViewModel.EditAddOrderActionMessage, null);
        dialogView.FindViewById<TextView>(Resource.Id.AddOrderButton).SetText(PartyDetailsViewModel.AddOrderButtonTitle, null);
        dialogView.FindViewById<TextView>(Resource.Id.AddOrderButton).Click += delegate {
            this.ViewModel.SelectedOrder = (PartyDetailsViewModel.AddOrderButtonTitle, contactGuid);
            alertDialog.Dismiss();
        };
       dialogView.FindViewById<ListView>(Resource.Id.GuestNameList).SetAdapter();
    }

【问题讨论】：

对话框是内置的文本消息。使用表单，可能是this PopUp plugin fits for you
您是指 ActionSheet 吗？
除了没有为您的 ListView 提供适配器之外，究竟是什么问题（？）？还是使用Adapter 属性与SetAdaptor 方法？

【解决方案1】：

对话框/列表视图示例：

var dialogView = LayoutInflater.Inflate(Resource.Layout.guest_name_list, null);
AlertDialog alertDialog;
using (var dialog = new AlertDialog.Builder(this))
{
    dialog.SetView(dialogView);
    dialog.SetNegativeButton("Cancel", (s, a) => { });
    alertDialog = dialog.Create();
}
var items = new string[] { "Stack", "Over", "Flow" };
var adapter = new ArrayAdapter<string>(this, Android.Resource.Layout.SimpleListItem1, items);
dialogView.FindViewById<ListView>(Resource.Id.GuestNameList).Adapter = adapter;
alertDialog.Show();
