在 Windows Phone 8 中播放默认视频

Question

我已经解析了 RSS 提要 http://www.teluguone.com/videosongs/videoSongsXml.php?cat_id=6。 并在水平列表视图中显示歌曲。如下所示

当我单击上面空间中正在播放的特定歌曲时。 但是，在这里我想获得默认视频以及水平列表视图。当我点击一个特定的视频时，它应该被播放。 如何获取默认视频以及列表视图。

XAML 代码：

            downloader.DownloadStringAsync(uri);
          }

          void VideosongsDownloaded(object sender, DownloadStringCompletedEventArgs e)

            if (e.Result == null || e.Error != null)
            {
                MessageBox.Show("There was an error downloading the XML-file!");
            }
            else
            {
                // Deserialize if download succeeds
                XDocument document = XDocument.Parse(e.Result);
                XmlSerializer serializer = new XmlSerializer(typeof(videosongs));
                videosongs videosongs = (videosongs)serializer.Deserialize(document.CreateReader());
                videosongList.ItemsSource = videosongs.Collection;
            }
        }

    private async void videosongList_SelectionChanged(object sender, SelectionChangedEventArgs e)
    {
        Songsdetails song = (Songsdetails)videosongList.SelectedItem;


        var url = await YouTube.GetVideoUriAsync(song.songcode, YouTubeQuality.Quality480P);
        player.Source = url.Uri;
    }
}

}

任何人都请给我任何关于让默认视频与水平列表视图一起播放的建议。 非常感谢。
