c# – 状态栏通知xamarin native android

我是Xamarin的新手,到目前为止这是我的代码.它不会给出任何错误或显示通知.

NotificationCompat.Builder builder = new NotificationCompat.Builder(Activity)
            .SetAutoCancel(true)
            .SetContentIntent(resultPendingIntent)
            .SetContentTitle("My Notifications")
            .SetContentText(" Work dammit -_-");
            notificationmanager notificationmanager = (notificationmanager)Activity.GetSystemService(Android.Content.Context.NotificationService);
            notificationmanager.Notify(ButtonClickNotification,builder.Build());

解决方法

我找到了解决问题的方法.

I got my solution from here

void CreateNotification(string title,string desc)
        {
            //Create notification
            var notificationmanager = GetSystemService(Context.NotificationService) as 
                 notificationmanager;

            //Create an intent to show ui
            var uiIntent = new Intent(this,typeof(MainActivity));

            //Create the notification
            var notification = new Notification(Resource.Drawable.Icon,title);
            //var notification = new Notification(Android.Resource.Drawable.SymActionEmail,title);

            //Auto cancel will remove the notification once the user touches it
            notification.Flags = NotificationFlags.AutoCancel;

            //Set the notification info
            //we use the pending intent,passing our ui intent over which will get called
            //when the notification is tapped.
            notification.SetLatestEventInfo(this,title,desc,PendingIntent.GetActivity(this,uiIntent,0));

            //Show the notification
            notificationmanager.Notify(1,notification);
        }
