Xamarin.forms如何播放安卓通知声音



我正在使用Xaminn.Forms PLC项目,现在我正在尝试在Android项目上设置通知的声音,我使用以下方法将通知添加到我的项目中:

assembly: Xamarin.Forms.Dependency (typeof (NotificationService))]

在下面,我用于显示通知的代码:

   var notification = new Notification.Builder (Application.Context)
    .SetContentTitle (message.Short_Message.ToString ())
    .SetContentText (message.Long_Message.ToString())
    .SetSmallIcon (Resource.Mipmap.ic_launcher)  
    .SetStyle(new Notification.BigTextStyle().BigText(message.Long_Message))   
    .SetPriority((int)NotificationPriority.Max) 
    .SetContentIntent(OpenAppOnCLickOnNotificaton)   
    .SetLights(255,1000,1000)
    .Build ();
    var manager = Application.Context.GetSystemService (Application.NotificationService) as NotificationManager;
        manager.Notify (message.ID, notification);

您可以按如下方式使用默认通知声音:

  .SetDefaults(NotificationDefaults.Sound)
