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?!
