很难创建Microsoft Band磁贴图标

Question

它在Microsoft Band SDK文档中说使用WriteableBitmap创建磁贴图标，但是如何让它指向我为Tile制作的现有图像？

Answer 1

如果您的Windows Phone应用程序有一个名为＆＃34; Assets / Icon1.png＆＃34;的资产，则该资产可以通过以下内容制作成BandIcon：

using Microsoft.Band;
using Microsoft.Band.Tiles;
using Microsoft.Band.Tiles.Pages;
using Windows.Storage;
using Windows.Storage.Streams;
using Windows.UI;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Media.Imaging;

...

StorageFile imageFile = await StorageFile.GetFileFromApplicationUriAsync(new Uri("ms-appx:///Assets/Icon1.png"));
using (IRandomAccessStream fileStream = await imageFile.OpenAsync(FileAccessMode.Read)
{
    WriteableBitmap bitmap = new WriteableBitmap(1,1);
    await bitmap.SetSourceAsync(fileStream);
    return bitmap.ToBandIcon();
}
