我有很多.wav
个文件可供使用,因此我创建了AudioItem
类:
public class AudioItem
{
public string SongName { get; set; }
public string SongText { get; set; }
public AudioItem()
{ }
/// <summary>
/// Initialize AudioItem class
/// </summary>
/// <param name="SongName">The name of the song(with .wav)</param>
/// <param name="SongText">Text to display</param>
public AudioItem(string SongName, string SongText)
{
this.SongName = SongName;
this.SongText = SongText;
}
public void Play()
{
var stream = TitleContainer.OpenStream("Sound/" + SongName);
var effect = SoundEffect.FromStream(stream);
FrameworkDispatcher.Update();
effect.Play();
}
}
在视图中,我有Listbox
个项目:
<ListBox Name="soundtrackLbx">
<ListBox.ItemTemplate>
<DataTemplate>
<Button Name="ListButton" HorizontalAlignment="Stretch" >
<Button.Content>
<StackPanel Orientation="Horizontal">
<Image Margin="10" Height="30" Width="30" Source="Picture/audio.png"/>
<TextBlock Margin="10" HorizontalAlignment="Stretch" Text="{Binding SongText}" FontFamily="Verdana" Tap="TextBlock_Tap" />
</StackPanel>
</Button.Content>
</Button>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
我的代码背后:
public ObservableCollection<AudioItem> AudioItems { get; set; }
public MainView()
{
InitializeComponent();
AudioItems = new ObservableCollection<AudioItem>();
Initialize();
this.soundtrackLbx.ItemsSource = AudioItems;
}
private void Initialize()
{
AudioItems.Add(new AudioItem("ApsolutnoDa.wav", "Apsolutno da"));
AudioItems.Add(new AudioItem("Da.wav", "Da"));
}
private void TextBlock_Tap(object sender, GestureEventArgs e)
{
TextBlock tblock = sender as TextBlock;
string text = tblock.Text;
AudioItem item = AudioItems.SingleOrDefault(a => a.SongText == text);
item.Play();
}
好吧,碰巧.wav
有时我会听到他们玩,有时候我不会,我不知道为什么会这样。
答案 0 :(得分:0)
行。在这里,如果有人像我一样被困。问题是因为我在Tap
上设置了Textblock
事件,而不是Button
。
我是如何从Button.Content
获取内容的?
我使用tag
属性并将其绑定到SongName
属性。
