如下面的图，很多应用都有活动磁贴，活动磁贴就是放在开始菜单，会像是下面图一样显示东西
做一个UWP当然需要我们打开神器
新建一个项目，空UWP，可以使用快捷键ctrl+shift+N
我们打开MainPage.xaml，新建的时候有点慢，我们需要等一下如果放在固态基本不用等。

写完我们可以看到下面的样子
上面一张是作者写的开始我没有去看，以为他写出来就是上面那图，复制了他代码在我写博客，发现他的代码错了，我自己重新写，发现我应该弄个中文，就写了第二张图，我们看到上面代码是第二张图。
我们右击方案新建一个文件夹DATA，里面新建一个类PrimaryTile，可以看下面图
我们在PrimaryTile
public class PrimaryTile
{
public string time
{
set;
get;
} = "8:15 AM, Saturday";
public string message
{
set;
get;
} = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore.";
public string message2
{
set;
get;
} = "At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident.";
public string branding
{
set;
get;
} = "name";
public string appName
{
set;
get;
} = "UWP";
}
创建一个文件夹services 新建tileservice.cs toastservice.cs
public class TileService
{
public static void SetBadgeCountOnTile(int count)
{
// Update the badge on the real tile
System.Xml.XmlDocument badgeXml = BadgeUpdateManager.GetTemplateContent(BadgeTemplateType.BadgeNumber);
XmlElement badgeElement = (XmlElement) badgeXml.SelectSingleNode("/badge");
badgeElement.SetAttribute("value", count.ToString());
BadgeNotification badge = new BadgeNotification(badgeXml);
BadgeUpdateManager.CreateBadgeUpdaterForApplication().Update(badge);
}
public static XmlDocument CreateTiles(PrimaryTile primaryTile)
{
XDocument xDoc = new XDocument(
new XElement("tile", new XAttribute("version", 3),
new XElement("visual",
// Small Tile
new XElement("binding", new XAttribute("branding", primaryTile.branding),
new XAttribute("displayName", primaryTile.appName), new XAttribute("template", "TileSmall"),
new XElement("group",
new XElement("subgroup",
new XElement("text", primaryTile.time, new XAttribute("hint-style", "caption")),
new XElement("text", primaryTile.message,
new XAttribute("hint-style", "captionsubtle"), new XAttribute("hint-wrap", true),
new XAttribute("hint-maxLines", 3))
)
)
),
// Medium Tile
new XElement("binding", new XAttribute("branding", primaryTile.branding),
new XAttribute("displayName", primaryTile.appName), new XAttribute("template", "TileMedium"),
new XElement("group",
new XElement("subgroup",
new XElement("text", primaryTile.time, new XAttribute("hint-style", "caption")),
new XElement("text", primaryTile.message,
new XAttribute("hint-style", "captionsubtle"), new XAttribute("hint-wrap", true),
new XAttribute("hint-maxLines", 3))
)
)
),
// Wide Tile
new XElement("binding", new XAttribute("branding", primaryTile.branding),
new XAttribute("displayName", primaryTile.appName), new XAttribute("template", "TileWide"),
new XElement("group",
new XElement("subgroup",
new XElement("text", primaryTile.time, new XAttribute("hint-style", "caption")),
new XElement("text", primaryTile.message,
new XAttribute("hint-style", "captionsubtle"), new XAttribute("hint-wrap", true),
new XAttribute("hint-maxLines", 3)),
new XElement("text", primaryTile.message2,
new XAttribute("hint-style", "captionsubtle"), new XAttribute("hint-wrap", true),
new XAttribute("hint-maxLines", 3))
),
new XElement("subgroup", new XAttribute("hint-weight", 15),
new XElement("image", new XAttribute("placement", "inline"),
new XAttribute("src", "Assets/StoreLogo.png"))
)
)
),
//Large Tile
new XElement("binding", new XAttribute("branding", primaryTile.branding),
new XAttribute("displayName", primaryTile.appName), new XAttribute("template", "TileLarge"),
new XElement("group",
new XElement("subgroup",
new XElement("text", primaryTile.time, new XAttribute("hint-style", "caption")),
new XElement("text", primaryTile.message,
new XAttribute("hint-style", "captionsubtle"), new XAttribute("hint-wrap", true),
new XAttribute("hint-maxLines", 3)),
new XElement("text", primaryTile.message2,
new XAttribute("hint-style", "captionsubtle"), new XAttribute("hint-wrap", true),
new XAttribute("hint-maxLines", 3))
),
new XElement("subgroup", new XAttribute("hint-weight", 15),
new XElement("image", new XAttribute("placement", "inline"),
new XAttribute("src", "Assets/StoreLogo.png"))
)
)
)
)
)
);
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.LoadXml(xDoc.ToString());
//Debug.WriteLine(xDoc);
return xmlDoc;
}
}
public static class ToastService
{
public static System.Xml.XmlDocument CreateToast()
{
XDocument xDoc = new XDocument(
new XElement("toast",
new XElement("visual",
new XElement("binding", new XAttribute("template", "ToastGeneric"),
new XElement("text", "To Do List"),
new XElement("text", "Is the task complete?")
) // binding
), // visual
new XElement("actions",
new XElement("action", new XAttribute("activationType", "background"),
new XAttribute("content", "Yes"), new XAttribute("arguments", "yes")),
new XElement("action", new XAttribute("activationType", "background"),
new XAttribute("content", "No"), new XAttribute("arguments", "no"))
) // actions
)
);
System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();
xmlDoc.LoadXml(xDoc.ToString());
return xmlDoc;
}
}
我们创建文件ToDoTask.cs ToDoTaskFileHelper.cs
public class ToDoTask
{
public string Description
{
get;
set;
}
public Guid Id
{
get;
set;
}
public bool? IsComplete
{
get;
set;
}
public string ToJson()
{
using (MemoryStream stream = new MemoryStream())
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof (ToDoTask));
serializer.WriteObject(stream, this);
stream.Position = 0;
byte[] jsonBytes = stream.ToArray();
return Encoding.UTF8.GetString(jsonBytes, 0, jsonBytes.Length);
}
}
public static ToDoTask FromJson(string json)
{
// note: throws exception if the json is not valid
JsonObject jsonData = JsonObject.Parse(json);
// exceptions will be thrown if the values do not match the types
return new ToDoTask
{
Id = Guid.Parse(jsonData["Id"].GetString()),
Description = jsonData["Description"].GetString(),
IsComplete = jsonData["IsComplete"].GetBoolean()
};
}
}
public static class ToDoTaskFileHelper
{
public static async Task ReadToDoTaskJsonAsync()
{
// declare an empty variable to be filled later
string json = null;
// define where the file resides
StorageFolder localfolder = ApplicationData.Current.LocalFolder;
// see if the file exists
if (await localfolder.TryGetItemAsync(Filename) != null)
{
// open the file
StorageFile textfile = await localfolder.GetFileAsync(Filename);
// read the file
json = await FileIO.ReadTextAsync(textfile);
}
// if the file doesn't exist, we'll copy the app copy to local storage
else
{
StorageFile storageFile =
await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Assets/task.json"));
await storageFile.CopyAsync(ApplicationData.Current.LocalFolder);
json = await FileIO.ReadTextAsync(storageFile);
}
return json;
}
public static async Task SaveToDoTaskJson(string json)
{
StorageFolder localfolder = ApplicationData.Current.LocalFolder;
StorageFile textfile = await localfolder.GetFileAsync(Filename);
await FileIO.WriteTextAsync(textfile, json);
}
private static readonly string Filename = "task.json";
}
task.json
{"Description":"A test task","Id":"9d6c3585-d0c2-4885-8fe0-f02727f8e483","IsComplete":true}
我们把刚才写的MainPage的按钮绑定到
public sealed partial class MainPage : Page, INotifyPropertyChanged
{
public MainPage()
{
InitializeComponent();
Loaded += MainPage_Loaded;
}
#region Delegates
public event PropertyChangedEventHandler PropertyChanged;
private void MainPage_Loaded(object sender, RoutedEventArgs e)
{
Refresh();
}
#endregion
public ToDoTask CurrentToDoTask
{
get
{
return _currentToDoTask;
}
set
{
_currentToDoTask = value;
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(nameof(CurrentToDoTask)));
}
}
private int _count;
private ToDoTask _currentToDoTask;
private async void Refresh()
{
void json = await ToDoTaskFileHelper.ReadToDoTaskJsonAsync();
CurrentToDoTask = ToDoTask.FromJson(json);
}
private void UpdateBadge(object sender, RoutedEventArgs e)
{
_count++;
TileService.SetBadgeCountOnTile(_count);
}
private void UpdatePrimaryTile(object sender, RoutedEventArgs e)
{
XmlDocument xmlDoc = TileService.CreateTiles(new PrimaryTile());
TileUpdater updater = TileUpdateManager.CreateTileUpdaterForApplication();
TileNotification notification = new TileNotification(xmlDoc);
updater.Update(notification);
}
private void Notify(object sender, RoutedEventArgs e)
{
System.Xml.XmlDocument xmlDoc = ToastService.CreateToast();
ToastNotifier notifier = ToastNotificationManager.CreateToastNotifier();
ToastNotification toast = new ToastNotification(xmlDoc);
notifier.Show(toast);
}
}
写完自己运行就可以知道，更新磁贴，更新界面，提示通知，每个对应的代码自己可以看到，这个国内很多教程
