首先,我将Xamarin Forms用于WP8,iOS和Android应用程序.

Goal:

I want to go to a specific page when the toast is clicked depending
upon the payload information of the toast notification.

我使用Azure Notification Hubs进行了推送通知,所有设置均正常运行.我使用MVVMlight及其依赖项注入来专门为每个平台设置推送通知.

由于所需的格式不同,每个有效载荷都需要发送一些不同的信息.对于每一个,您都会注意到我想在有效负载中发送SignalID,以根据常规推送通知在接收设备上执行所需的不同 *** 作.

安卓系统

{  "data" : {    "msg" : "message in here",    "signalID" : "ID-in-here",  },}

的iOS

{    "aps" : { "alert" : "message in here" },    "signalID" : "ID-in-here"}

windows Phone 8

 <?xml version="1.0" enCoding="utf-8"?> <wp:Notification xmlns:wp="WPNotification">     <wp:Toast>          <wp:Text1>category</wp:Text1>          <wp:Text2>message in here</wp:Text2>          <wp:Param>?signalID=ID-in-here</wp:Param>     </wp:Toast> </wp:Notification>

.

Question:

How do I get this information in a Xamarin Forms app and redirect to
the appropriate page when the application is reactivated because the
user clicked on the toast notification?

我想在应用程序加载时获取有效负载信息,然后说,是的,其中包含SignalID,让我们重定向到此页面.

目前,它会执行所有 *** 作,并在单击烤面包通知时显示该应用程序.我必须针对该应用程序执行此 *** 作,还是可以使用Xamarin Forms方式？

即使您只知道如何在一个平台上进行 *** 作,也应感谢您的帮助,我可能可以从那里在其他平台上工作.

解决方法:

我已经找到了在所有平台上执行此 *** 作的方法. windows已经过测试,AndroID和iOS尚未经过测试.

如果应用程序在后台,则windows和iOS会在show toast通知上工作,如果应用程序在前台,则让您的代码处理它.不论应用程序状态如何,AndroID都会显示吐司.

使用windows Phone 8,我需要转到MainPage.xaml.cs并添加此替代项.

protected overrIDe voID OnNavigatedTo(System.windows.Navigation.NavigationEventArgs e)    {        base.OnNavigatedTo(e);        if (this.NavigationContext.queryString.ContainsKey("signalID"))        {            var signalID = this.NavigationContext.queryString["signalID"];            var ID = GuID.Empty;            if (signalID != null                && GuID.TryParse(signalID, out ID)                && ID != GuID.Empty)            {                this.NavigationContext.queryString.Clear();                Deployment.Current.dispatcher.BeginInvoke(() =>                {                    // Do my navigation to a new page                });            }        }    }

对于GCMService中的AndroID

  protected overrIDe voID OnMessage(Context context, Intent intent)        {            Log.Info(Tag, "GCM Message Received!");            var message = intent.Extras.Get("msg").ToString();            var signalID = GuID.Empty;            if (intent.Extras.ContainsKey("signalID"))            {                signalID = new GuID(intent.Extras.Get("signalID").ToString());            }                // Show notification as usual                CreateNotification("", message, signalID);        }

然后在CreateNotification函数中,在Intent中添加一些额外的信息.

            var uiIntent = new Intent(this, typeof(MainActivity));            if (signalID != GuID.Empty)            {                uiIntent.PutExtra("SignalID", signalID.ToString());            }

然后在MainActivity.cs中覆盖此功能

protected overrIDe voID OnActivityResult(int requestCode, Result resultCode, Intent data)    {        if (data.HasExtra("SignalID"))        {            GuID signalID = new GuID(data.GetStringExtra("SignalID"));            if (signalID != GuID.Empty)            {                data.RemoveExtra("SignalID");                // Do you navigation            }        }    }

在iOS中,您会注意到我已经增强了默认的ProcessNotification()

  voID ProcessNotification(NSDictionary options, bool fromFinishedLaunching)    {        // Check to see if the dictionary has the aps key.  This is the notification payload you would have sent        if (null != options && options.ContainsKey(new Nsstring("aps")))        {            //Get the aps dictionary            var aps = options.ObjectForKey(new Nsstring("aps")) as NSDictionary;            var alert = string.Empty;            //Extract the alert text            // NOTE: If you're using the simple alert by just specifying             // "  aps:{alert:"alert msg here"}  " this will work fine.            // But if you're using a complex alert with Localization keys, etc.,             // your "alert" object from the aps dictionary will be another NSDictionary.             // Basically the Json gets dumped right into a NSDictionary,             // so keep that in mind.            if (aps.ContainsKey(new Nsstring("alert")))                alert = ((Nsstring) aps[new Nsstring("alert")]).ToString();            // If this came from the ReceivedRemoteNotification while the app was running,            // we of course need to manually process things like the sound, badge, and alert.            if (!fromFinishedLaunching)            {                //Manually show an alert                if (!string.IsNullOrEmpty(alert))                {                    var signalID = new GuID(options.ObjectForKey(new Nsstring("signalID")) as Nsstring);                    // Show my own toast with the signalID                }            }        }    }

然后在FinishedLaunching函数中检查是否有任何有效负载

        // Check if any payload from the push notification        if (options.ContainsKey("signalID"))        {            var signalID = new GuID(options.ObjectForKey(new Nsstring("signalID")) as Nsstring);            // Do the navigation here                 }
