Windows Phone 8.1 Tiles, notifications and Action Center

(1) Tiles

Tiles, which is a tile, is a feature of Windows Phone.

A Tile can actually be seen as an XML, such as:

<Tile>  <Visual>    <bindingTemplate= "Tilesquareimage">      <ImageID= "1"src= "Image1"alt= "alt text"/>    </binding>    </Visual></Tile><Tile>  <Visualversion= "2">    <bindingTemplate= "Tilesquare150x150image"fallback= "Tilesquareimage">      <ImageID= "1"src= "Image1"alt= "alt text"/>    </binding>    </Visual></Tile>

Microsoft has provided us with a series of templates that can be referenced by: links

Tile can be easily updated as long as it is based on the XML format of the template:

Private voidUpdatebutton_click (Objectsender, RoutedEventArgs e) {Updatetiles ("Ms-appx:///images/middle.png","Ms-appx:///images/wide.png");}Private voidUpdatetiles (stringMiddlepath,stringWidepath) {    stringTilestring ="<tile>"+"<visual version=\ "2\" >"+"<binding template=\ "tilesquare150x150peekimageandtext04\" fallback=\ "tilesquarepeekimageandtext04\" > "+"<image id=\ "1\" src=\ ""+ Middlepath +"\ "alt=\" alt text\ "/>"+"<text id=\ "1\" ></text>"+"</binding>"+"<binding template=\ "tilewide310x150imageandtext01\" fallback=\ "tilewideimageandtext01\" >"+"<image id=\ "1\" src=\ ""+ Widepath +"\ "alt=\" alt text\ "/>"+"<text id=\ "1\" ></text>"+"</binding>"+"</visual>"+"</tile>"; XmlDocument Tilexml=NewXmlDocument ();    Tilexml.loadxml (tilestring); Tilenotification Newtile=Newtilenotification (Tilexml); Tileupdater Updater=tileupdatemanager.createtileupdaterforapplication (); Updater. Enablenotificationqueue (false); Updater. Update (newtile);}

In addition to the main tile we can also create a new secondarytile:

Private voidCreatebutton_click (Objectsender, RoutedEventArgs e) {Createtile ("Ms-appx:///images/middle.png","Ms-appx:///images/wide.png");}Private Async voidCreatetile (stringMiddlepath,stringWidepath) {Secondarytile Tile=NewSecondarytile ("Cortana","Cortana","Some",NewUri (Middlepath), tilesize.default); Tile. Visualelements.shownameonsquare150x150logo=true; Tile. Visualelements.foregroundtext=Foregroundtext.dark; Tile. Visualelements.square30x30logo=NewUri (Middlepath); Tile. Visualelements.wide310x150logo=NewUri (Widepath); awaitTile. Requestcreateasync ();}

The secondarytile update is the same as the primary tile update:

Tileupdater update = Tileupdatemanager.createtileupdaterforsecondarytile ("Cortana");

(2) Notifications

Notification (push notification) is divided into Tile,badge,toast,raw four types, and the method of notification is divided into Scheduled,periodic,local,push four kinds, the corresponding relationship between them is:

The use of the method is similar, the Update method can be called according to the respective XML format modification, for example:

XmlDocument xml =new= toastnotificationmanager.createtoastnotifier (); notifier. Show (toast);

Note that: (1) The TOAST notification needs to be licensed in Manifest; (2) The Push method is:

 private  async   Sendrawnotification () { var  channel = await   channel_pushnotificationreceived;}  private  void   channel_pushnotificationreceived (Pushnotificationchannel sender, Pushnotificationreceivedeventargs args) { var  raw = args. rawnotification;}  

(3) Action Center

1) Each app can host up to 20 notifications in Action Center

2) notifications can reside for up to 7 days

3) can send silent notifications (users are not prompted)

true;

4) notifications can be grouped

XmlDocument xml =new"one""1  ";

5) can update or delete notifications (you can delete a group)

ToastNotificationManager.History.RemoveGroup ("one");
