Question

我已经解析了RSS Feed 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 enter image description here

当我点击特定歌曲时，它正在上面的空间中播放。但是，在这里我想获得默认视频和水平列表视图。当我点击特定视频时，它应该播放。如何获取默认视频以及列表视图。

XAML代码：

                        </StackPanel>

XAML.cs的代码：

namespace PhoneApp1
   {
        public partial class MainPage : PhoneApplicationPage
       {
          public MainPage()
        {
             InitializeComponent();
        }
        private void PhoneApplicationPage_Loaded(object sender, RoutedEventArgs e)
        {
            // is there network connection available
             if (!System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable())
            {
                MessageBox.Show("No network connection available!");
                return;
            }
            // start loading XML-data
            WebClient downloader = new WebClient();
            Uri uri = new Uri("http://www.teluguone.com/videosongs/videoSongsXml.php?cat_id=6", UriKind.Absolute);
            downloader.DownloadStringCompleted += new DownloadStringCompletedEventHandler(VideosongsDownloaded);
            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;
    }
}

}

任何人都可以给我任何关于获取默认视频和水平列表视图的建议。非常感谢。
