状态栏通知 Xamarin 原生安卓

Question

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());

Answer 1

我找到了解决问题的方法。

我从这里得到了我的解决方案

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, 0, uiIntent, 0));
//Show the notification
notificationManager.Notify(1, notification);
}

如文档中所述，在调用builder.Build()之前，需要用SetSmallIcon()设置一个小图标。这很可能是你的问题点，因为你的代码似乎没有其他问题。
