c# - Windows Phone 8.1 Silverlight中的Toast通知参数

好的，所以我在8.1 SL项目中使用的是新的ToastNotificationManager，而不是旧的ShellToast。 ShellToast在Toast消息上包含了NavigationUri，这非常容易。

在新的 toast 中，您必须根据this文章自行指定启动参数。但是，似乎8.1 SL没有应该在App.xaml.cs中监听以下参数的事件OnLaunched(LaunchActivatedEventArgs args):

protected override void OnLaunched(LaunchActivatedEventArgs args)
{
    string launchString = args.Arguments

    ....
}

我的代码:

// Using the ToastText02 toast template.
ToastTemplateType toastTemplate = ToastTemplateType.ToastText02;

// Retrieve the content part of the toast so we can change the text.
XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(toastTemplate);

//Find the text component of the content
XmlNodeList toastTextElements = toastXml.GetElementsByTagName("text");

// Set the text on the toast.
// The first line of text in the ToastText02 template is treated as header text, and will be bold.
toastTextElements[0].AppendChild(toastXml.CreateTextNode("Heading"));
toastTextElements[1].AppendChild(toastXml.CreateTextNode("Body"));

// Set the duration on the toast
IXmlNode toastNode = toastXml.SelectSingleNode("/toast");
((XmlElement)toastNode).SetAttribute("duration", "long");

//Launch params
string paramString = "{\"type\":\"toast\",\"param1\":\"12345\"}";
((XmlElement)toastXml.SelectSingleNode("/toast")).SetAttribute("launch", paramString);

// Create the actual toast object using this toast specification.
ToastNotification toast = new ToastNotification(toastXml);

// Set SuppressPopup = true on the toast in order to send it directly to action center without
// producing a popup on the user's phone.
toast.SuppressPopup = true;

// Send the toast.
ToastNotificationManager.CreateToastNotifier().Show(toast);

有人知道如何解决这个问题吗？
谢谢

最佳答案

您的问题是您设置了错误的launch参数。您应该将其直接设置到要导航到的页面。

var toastNavigationUriString = ""#/MainPage.xaml?param1=12345";
var toastElement = ((XmlElement)toastXml.SelectSingleNode("/toast"));
toastElement.SetAttribute("launch", toastNavigationUriString);
