Question

我试图了解是否可以显示倒数计时器，例如某种动画或任何动态的吐司通知？

看看微软的这篇文章

https://docs.microsoft.com/en-us/windows/uwp/design/shell/tiles-and-notifications/toast-progress-bar

这显示了如何在UWP应用程序中向Toast Notification添加进度条。

首先使用特定标记创建Toast通知

using Windows.UI.Notifications;
using Microsoft.Toolkit.Uwp.Notifications;

public void SendUpdatableToastWithProgress()
{
    // Define a tag (and optionally a group) to uniquely identify the notification, in order update the notification data later;
    string tag = "weekly-playlist";
    string group = "downloads";

    // Construct the toast content with data bound fields
    var content = new ToastContent()
    {
        Visual = new ToastVisual()
        {
            BindingGeneric = new ToastBindingGeneric()
            {
                Children =
                {
                    new AdaptiveText()
                    {
                        Text = "Downloading your weekly playlist..."
                    },

                    new AdaptiveProgressBar()
                    {
                        Title = "Weekly playlist",
                        Value = new BindableProgressBarValue("progressValue"),
                        ValueStringOverride = new BindableString("progressValueString"),
                        Status = new BindableString("progressStatus")
                    }
                }
            }
        }
    };

    // Generate the toast notification
    var toast = new ToastNotification(content.GetXml());

    // Assign the tag and group
    toast.Tag = tag;
    toast.Group = group;

    // Assign initial NotificationData values
    // Values must be of type string
    toast.Data = new NotificationData();
    toast.Data.Values["progressValue"] = "0.6";
    toast.Data.Values["progressValueString"] = "15/26 songs";
    toast.Data.Values["progressStatus"] = "Downloading...";

    // Provide sequence number to prevent out-of-order updates, or assign 0 to indicate "always update"
    toast.Data.SequenceNumber = 1;

    // Show the toast notification to the user
    ToastNotificationManager.CreateToastNotifier().Show(toast);
}

然后您可以使用该标记更新Toast Notification

using Windows.UI.Notifications;

public void UpdateProgress()
{
    // Construct a NotificationData object;
    string tag = "weekly-playlist";
    string group = "downloads";

    // Create NotificationData and make sure the sequence number is incremented
    // since last update, or assign 0 for updating regardless of order
    var data = new NotificationData
    {
        SequenceNumber = 2
    };

    // Assign new values
    // Note that you only need to assign values that changed. In this example
    // we don't assign progressStatus since we don't need to change it
    data.Values["progressValue"] = "0.7";
    data.Values["progressValueString"] = "18/26 songs";

    // Update the existing notification's data by using tag/group
    ToastNotificationManager.CreateToastNotifier().Update(data, tag, group);
}

是否可以在uwp toast通知中显示动画？
