Windows 8学习笔记(十)----Notification
WinRT中Notification有三种类型：Badge：徽章、标记的推送更新，主要对于磁砖进行通知
Toast：土司推送，一般是程序运行时通知
Tile：磁砖推送，自然就是程序处理休眠状态时的通知
注意：这里有消息内容都是以XML内容模板发送的
先研究下磁砖的推送Badge和Tile
Badge
了解一下有哪些方法
BadgeNotification(XmlDocument content)
BadgeUpdateManager
CreateBadgeUpdaterForApplication()---为当前应用更新磁砖
CreateBadgeUpdaterForApplication(string applicationID)---为指定的应用更新磁砖
有个疑问，这里的applicationID一般在哪儿得到？？还望知道的告知一下哦~
CreateBadgeUpdaterForSecondaryTile(string tileID)—为指定的磁砖更新
GetTemplateContent(BadgeTemplateType type)—获取预定义好的XML徽章模板
BadgeUpdater
Update(BadgeNotification notification)
示例代码:
XmlDocument badgeXml = BadgeUpdateManager.GetTemplateContent(BadgeTemplateType.BadgeNumber);
XmlElement badgeElement = (XmlElement)badgeXml.SelectSingleNode("/badge");
// We are setting attribute value 6
badgeElement.SetAttribute("value", "6");
// Create a badge notification from XML
BadgeNotification badgeNotification = new BadgeNotification(badgeXml);
// Send the notification to the secondary tile
BadgeUpdater badgeUpdater = BadgeUpdateManager.CreateBadgeUpdaterForSecondaryTile(MainPage.dynamicTileId);
badgeUpdater.Update(badgeNotification);
Tile
它包含的方法跟Badge类似
TileNotification(XmlDocument document)
TileUpdateManager
包手中四个方法，跟BadgeUpdateManager类似
CreateTileUpdaterForApplication()
CreateTileUpdaterForApplication(string applicationID)
CreateTileUpdaterForSecondaryTile(string tileID)
GetTemplateContent
TileUpdater--Update(TileNotificaton notification)
示例代码：
XmlDocument tileXml = TileUpdateManager.GetTemplateContent(TileTemplateType.TileWideText04);
// Refer to template documentation to determine how many text fields a particular template has
// get the text attributes for this template and fill them in
XmlNodeList tileTextElements = tileXml.GetElementsByTagName("text");
tileTextElements.Item(0).AppendChild(tileXml.CreateTextNode("Sent to a secondary tile!"));
XmlDocument squareTileXml = TileUpdateManager.GetTemplateContent(TileTemplateType.TileSquareText04);
XmlNodeList squareTileTextElements = squareTileXml.GetElementsByTagName("text");
squareTileTextElements.Item(0).AppendChild(squareTileXml.CreateTextNode("Sent to a secondary tile!"));
// Include the square template in the notification
IXmlNode subNode = tileXml.ImportNode(squareTileXml.GetElementsByTagName("binding").Item(0), true);
tileXml.GetElementsByTagName("visual").Item(0).AppendChild(subNode);
// Create the notification from the XML
TileNotification tileNotification = new TileNotification(tileXml);
// Send the notification to the secondary tile by creating a secondary tile updater
TileUpdater tileUpdater = TileUpdateManager.CreateTileUpdaterForSecondaryTile(MainPage.dynamicTileId);
tileUpdater.Update(tileNotification);
Toast
方法和属性也基本类似
但我下面的代码有问题，没有显示Toast通知，注册Failed事件，跟踪说是应用程序功能会阻止通知传递。 (异常来自 HRESULT:0x803E0112)
XmlDocument toastXml = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText01);
XmlNodeList textNodes = toastXml.GetElementsByTagName("text");
textNodes.Item(0).AppendChild(toastXml.CreateTextNode("Sent to Toast Notification!"));
ToastNotification toastNotification = new ToastNotification(toastXml);
toastNotification.Failed += toastNotification_Failed;
toastNotification.Dismissed += toastNotification_Dismissed;
ToastNotifier notifier = ToastNotificationManager.CreateToastNotifier();
在MSDN Sample里有Toast Sample示例，里面封装了NotificationExtensions扩展，很容易就可以实现通知更新，不需要编辑复杂的XML模板，但很纠结，我上面的代码有啥问题？？
NotificationsExtensions微软示例给我们封装的类库，非常方便，得学习一下大师的封装逻辑。。。
磁砖的更新还算简单，PushNotification有点摸不着头脑，首先PushChannel都是要手动输入，这个不是生成的么，很纠结，还希望有研究的同胞能提供点学习资料，跟Phone7的机制不太一样呢？！
