Xamarin中通知操作按钮的调用方法

Question

我正在处理Xamarin通知。我可以使用操作按钮发送通知， 我想单击操作按钮来执行某些功能。

代码为波纹管。

var builder = new NotificationCompat.Builder(this)
    .SetContentIntent(contentIntent)
    // .SetContentTitle("Sample Notification")
    //.SetContentText("Hello World! This is my first notification!")
    .SetContentTitle(title)
    .SetContentText(notiBody)
    //  AddAction(Int32 icon, String title, PendingIntent intent)
    .AddAction(Resource.Drawable.postComment, "Approve", contentIntent)
    .AddAction(Resource.Drawable.deleteIcon, "Reject", contentIntent)
    .SetSmallIcon(Resource.Drawable.logoCS)
    .SetPriority((int)NotificationPriority.Max)
    .SetAutoCancel(true);

// Build the notification:
Notification notification = builder.Build();

// Get the notification manager:
NotificationManager notificationManager =
GetSystemService(Context.NotificationService) as NotificationManager;

// Publish the notification:
const int notificationId = 0;
notificationManager.Notify(notificationId, notification);
