我的实时图块有问题。我会在实时图块中显示我的应用程序中产生声音的歌曲名称。 我在MainPage.xaml.cs中使用:
public MainPage()
{
InitializeComponent();
// Application Tile is always the first Tile, even if it is not pinned to Start.
ShellTile TileToFind = ShellTile.ActiveTiles.First();
// Application should always be found
if (TileToFind != null)
{
// if Count was not entered, then assume a value of 0
// set the properties to update for the Application Tile
// Empty strings for the text values and URIs will result in the property being cleared.
StandardTileData NewTileData = new StandardTileData
{
Title = "MyNameApp",
BackgroundImage = new Uri("Red.jpg", UriKind.Relative),
BackTitle = "Zzz...",
BackBackgroundImage = new Uri("Green.jpg", UriKind.Relative),
BackContent = txtCurrentTrack.Text <<HERE MY PROBLEM
};
// Update the Application Tile
TileToFind.Update(NewTileData);
}
}
并在MainPage.xaml中:
<TextBlock x:Name="txtCurrentTrack" Height="75" HorizontalAlignment="Center" Margin="12,193,0,0" VerticalAlignment="Top" Width="438" TextWrapping="Wrap"/>
在App的MainPage中,出现的歌曲标题不会出现在实时图块中。 你知道这是什么问题吗? Thnx对所有人
编辑:
我在这里设置了txtcurrentTrack.Text(在MainPage.xaml.cs中):
void Instance_PlayStateChanged(object sender, EventArgs e)
{
switch (BackgroundAudioPlayer.Instance.PlayerState)
{
case PlayState.Playing:
RelaxTB.Content = "pause";
break;
case PlayState.Paused:
case PlayState.Stopped:
RelaxTB.Content = "play";
break;
}
if (null != BackgroundAudioPlayer.Instance.Track)
{
txtCurrentTrack.Text = BackgroundAudioPlayer.Instance.Track.Title;
}
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
if (PlayState.Playing == BackgroundAudioPlayer.Instance.PlayerState)
{
RelaxTB.Content = "Pause";
txtCurrentTrack.Text = BackgroundAudioPlayer.Instance.Track.Title;
}
else
{
RelaxTB.Content = "Play";
txtCurrentTrack.Text = "";
}
}
答案 0 :(得分:0)
txtCurrentTrack上的Text属性似乎没有在更新切片数据时设置。因此,您只能将BackContent属性设置为null。
You need to update the tile explicitly each time you change txtCurrentTrack.Text
- 在Instance_PlayStateChanged和OnNavigatedTo方法中。
