单击确定按钮时AlertDialog无法关闭-C＃xamarin

Question

大家好，列表视图中有两个按钮。 当我单击拒绝按钮Alertdialog时，我必须输入原因..在OK上输入原因后，单击AlertDialog应该关闭。

每件东西都保存到DB ..但是警报对话框并没有关闭...而是输入了其关闭的三倍..我已经在下面插入了我的代码。

      btnReject.Click += delegate
            {
                var currentItem = item;
                Console.WriteLine(position);


                AlertDialog.Builder alert = new AlertDialog.Builder(this.context);
                LayoutInflater inflater = Application.Context.GetSystemService(Context.LayoutInflaterService) as LayoutInflater;
                View viewdialog = inflater.Inflate(Resource.Layout.RejectJobsAlertDialog, null);
                EditText getreason = viewdialog.FindViewById<EditText>(Resource.Id.Reason);
                alert.SetTitle("Reject Reason ");
                alert.SetView(viewdialog);
                alert.SetPositiveButton("Ok", (senderAlert, args) =>
                {

                    item.RejectedReason = getreason.Text;
                    sharedasproxy.MobileJobdetailsUpdate(item, BASE_URL + "/xxxxx");
                    Toast.MakeText(this.context, "success!", ToastLength.Short).Show();
                    btnReject.Visibility = ViewStates.Invisible;
                    btnAccept.Visibility = ViewStates.Visible;

                    dialog.Cancel();
                });

                alert.SetNegativeButton("Cancel", (senderAlert, args) =>
                {
                    Toast.MakeText(this.context, "Cancelled!", ToastLength.Short).Show();
                    CloseDialog();
                });


                dialog = alert.Create();


                dialog.Show();




            };

• 确保没有多次单击按钮单击事件。
• 代替编写委托，在click事件中调用一个方法。

尝试以下类似的方法，

 if (!btnReject.HasOnClickListeners)
    {

btnReject.Click += delegate
            {
                var currentItem = item;

                AlertDialog.Builder alert = new AlertDialog.Builder(this.context);
                LayoutInflater inflater = Application.Context.GetSystemService(Context.LayoutInflaterService) as LayoutInflater;
                View viewdialog = inflater.Inflate(Resource.Layout.RejectJobsAlertDialog, null);
                EditText getreason = viewdialog.FindViewById<EditText>(Resource.Id.Reason);
                alert.SetTitle("Reject Reason ");
                alert.SetView(viewdialog);
                alert.SetPositiveButton("Ok", (senderAlert, args) =>
                {

                    item.RejectedReason = getreason.Text;
                    sharedasproxy.MobileJobdetailsUpdate(item, BASE_URL + "/xxxxx");
                    Toast.MakeText(this.context, "success!", ToastLength.Short).Show();
                    btnReject.Visibility = ViewStates.Invisible;
                    btnAccept.Visibility = ViewStates.Visible;
                    dialog.Cancel();
                });

                alert.SetNegativeButton("Cancel", (senderAlert, args) =>
                {
                    Toast.MakeText(this.context, "Cancelled!", ToastLength.Short).Show();
                    CloseDialog();
                });    

                dialog = alert.Create();
                dialog.Show();


            };
}
