平铺通知在Windows 8.1中不起作用 [英] Tile notification not working in windows 8.1

问题描述

我使用此代码向我的应用程序发送本地磁贴通知

 XmlDocument tileXml = TileUpdateManager.GetTemplateContent（TileTemplateType.TileWide310x150ImageAndText01）; 
 XmlNodeList tileTextAttributes = tileXml.GetElementsByTagName（" text"）; 
 tileTextAttributes [0] .InnerText =" Test text" ;; 
 XmlNodeList tileImageAttributes = tileXml.GetElementsByTagName（" image"）; 
（（XmlElement）tileImageAttributes [0]）。SetAttribute（" src"，" http：//zetice.com/picture.png"）; 
 
 TileNotification tileNotification = new TileNotification（tileXml）; 
 // tileNotification.ExpirationTime = DateTimeOffset.UtcNow.AddDays（1）; 
 tileNotification.Tag =" TestTag" ;; 
 TileUpdateManager.CreateTileUpdaterForApplication（）。更新（tileNotification）; 

但是这段代码什么也没做。当我看到应用程序磁贴时，我看不到任何变化。是的我启用了通知。

奇怪的是，吐司通知有效。它只是瓦片通知不起作用。有谁知道问题是什么？

解决方案

我没有看到图像 http://zetice.com/picture.png  。你有正确的URL吗？除此之外，您的代码看起来非常正确。请参阅

Quickstart ：为类似示例发送磁贴更新。

您还只设置了宽磁贴，因此如果用户有一个正方形，则不会显示。

对于辅助功能，您应该始终在图像上设置alt标记，但我认为您只是为了示例而将其保留。

I used this code to send a local tile notification to my app

            XmlDocument tileXml = TileUpdateManager.GetTemplateContent(TileTemplateType.TileWide310x150ImageAndText01);
            XmlNodeList tileTextAttributes = tileXml.GetElementsByTagName("text");
            tileTextAttributes[0].InnerText = "Test text";
            XmlNodeList tileImageAttributes = tileXml.GetElementsByTagName("image");
            ((XmlElement)tileImageAttributes[0]).SetAttribute("src", "http://zetice.com/picture.png");

            TileNotification tileNotification = new TileNotification(tileXml);
            //    tileNotification.ExpirationTime = DateTimeOffset.UtcNow.AddDays(1);
            tileNotification.Tag = "TestTag";
            TileUpdateManager.CreateTileUpdaterForApplication().Update(tileNotification);

But this code does nothing. When i look at the app tile, i see no change. Yes i have notifications enabled.

Weird thing is that, toast notifiction works. It's just tile notifications that doesnt work. Anyone know what the problem is?

解决方案

I don't see an image at http://zetice.com/picture.png . Do you have the right URL? Other than that your code looks superficially correct. See Quickstart: Sending a tile update for a similar example.

You're also setting just the wide tile, so if the user has a square one set this won't show up.

For accessibility you should always set the alt tag on your image, but I assume that you left that out just for the example's sake.
