Windows Phone 7 Toast 通知，应用程序在前台 [英] Windows phone 7 Toast notification with app in foreground

问题描述

快速提问.我是这样做的:

Quick question. I did this:

myChannel.ShellToastNotificationReceived += new EventHandler<NotificationEventArgs>(myChannel_ShellToastNotificationReceived);

因此，如果我在应用程序处于前台时收到 Toast 通知，则应调用 myChannel_ShellToastNotificationReceived 函数.在该功能中，我有:

So if I receive a toast notification while the application is in the foreground the myChannel_ShellToastNotificationReceived function should be called. In that function I have:

void myChannel_ShellToastNotificationReceived(object sender, NotificationEventArgs e)
{
    Dispatcher.BeginInvoke(() =>
    {
       ApplicationTitle.Text = "Toast Notification Message Received";
    });
}

问题是函数从未被调用，ApplicationTitle 也从未改变.

The problem is that the function is never called and the ApplicationTitle is never changed.

我做错了什么吗?

推荐答案

我发现了问题...看来正在发送的 toast xml 的格式已经足够好，因此手机可以从应用程序中接收它但不是当它在里面的时候.手工"写了xml，没有使用xmlWriter，工作正常.

I've found the problem...it seemed that the toast xml that was being sent was well enough formatted so the phone would receive it out of the app but not when it was inside it. Wrote the xml by "hand" and didn't use xmlWriter and worked.

string toastMessage = "<?xml version=\"1.0\" encoding=\"utf-8\"?>" +
        "<wp:Notification xmlns:wp=\"WPNotification\">" +
           "<wp:Toast>" +
              "<wp:Text1>" + title + "</wp:Text1>" +
              "<wp:Text2>" + message + "</wp:Text2>" +
           "</wp:Toast>" +
        "</wp:Notification>";
