如何在“Listview”中的最后一首歌曲之后停止播放音乐

【中文标题】如何在“Listview”中的最后一首歌曲之后停止播放音乐

【英文标题】：How to stop music playing after last song in `Listview`

【发布时间】：2020-06-09 15:07:17

【问题描述】：

在我的 Raspberry pi3 的 UWP 应用程序中，我有一个音乐播放器，可以播放来自 ListView 的歌曲。您可以在ListView 中选择任何一首歌曲，然后它会自动播放下一首歌曲。我面临的问题是，当它到达最后一首歌曲并完成时，它会再次播放并且不会停止。就像它在最后一首歌曲中循环播放，而不是在播放完后停止。

有人可以指导我如何停止循环吗？

这是我的代码：

    private async void SongClicked(object sender, ItemClickEventArgs e)
    
        var file = await KnownFolders.MusicLibrary.GetFileAsync(e.ClickedItem.ToString());
        if (file != null)
        
            var stream = await file.OpenReadAsync();
            mediaElement.SetSource(stream, file.ContentType);
            mediaElement.Play();
        
    

    private void mediaItemList_SelectionChanged(object sender, SelectionChangedEventArgs e)
    

    

    private void objMediaPlayer_MediaOpened(object sender, RoutedEventArgs e)
    
        mediaElement.Play();
    

    private async void objMediaPlayer_MediaEnded(object sender, RoutedEventArgs e)
    
        if (AudioFilesLV.SelectedIndex <= AudioFilesLV.Items.Count)
        
            AudioFilesLV.SelectedIndex = AudioFilesLV.SelectedIndex = 1;
            var file = await KnownFolders.MusicLibrary.GetFileAsync(AudioFilesLV.SelectedItem.ToString());
            if (file != null)
            
                var stream = await file.OpenReadAsync();
                mediaElement.SetSource(stream, file.ContentType);
                mediaElement.Play();
            
        
        else
        
            mediaElement.Stop();
        
    

任何帮助将不胜感激。

谢谢。

【问题讨论】：

在 selectedIndex if 语句中尝试使用

您好，谢谢，我试过了，但没有用，仍然重复播放最后一个。

【参考方案1】：

您好，欢迎来到 ***， 问题可能出在事件 objMediaPlayer_MediaEnded 的 if 条件的第一行。因为你到达列表的末尾并设置

AudioFilesLV.SelectedIndex = AudioFilesLV.SelectedIndex = 1;

SelectedIndex 现在应该再次小于 AudioFilesLV.Items.Count。

该行应更改为：

AudioFilesLV.SelectedIndex = AudioFilesLV.SelectedIndex + 1;

因为那么你在 if 情况下计算 SelectedIndex。目前，SelectedIndex 应始终为 1。

如果你需要计算 SelectedIndex 来选择下一首歌曲，她就是一个例子：

private async void objMediaPlayer_MediaEnded(object sender, RoutedEventArgs e)

    // If the end of the ListView is reached and the last song was played stop.
    if ((AudioFilesLV.SelectedIndex + 1) == AudioFilesLV.Items.Count)
    
       mediaElement.Stop();
    
    else
    
       // This line you should try to change. When the last song was not played 
       //-> select next one and play them.
        AudioFilesLV.SelectedIndex = AudioFilesLV.SelectedIndex + 1;
        var file = await KnownFolders.MusicLibrary.GetFileAsync(AudioFilesLV.SelectedItem.ToString());
        if (file != null)
        
            var stream = await file.OpenReadAsync();
            mediaElement.SetSource(stream, file.ContentType);
            mediaElement.Play();
        
    

然后告诉你我为什么这样做：

(AudioFilesLV.SelectedIndex + 1)

在示例中。因为在每种情况下，AudioFilesLV.SelectedIndex（SelectedIndex 从 0 开始）都比 AudioFilesLV.Items.Count（Count 从 1 开始）小一。

希望对你有帮助。

【讨论】：

谢谢，没听懂你说的。你能按照我上面的代码举个例子吗？

您好，我希望示例没问题，可以帮助您解决问题。

太棒了，谢谢你现在正在工作，也谢谢你的解释！！

【参考方案2】：

试试这个，

private async void objMediaPlayer_MediaEnded(object sender, RoutedEventArgs e)
    
        AudioFilesLV.SelectedIndex += 1;
        if (AudioFilesLV.SelectedIndex <= AudioFilesLV.Items.Count - 1)
        
            var file = await KnownFolders.MusicLibrary.GetFileAsync(AudioFilesLV.SelectedItem.ToString());
            if (file != null)
            
                var stream = await file.OpenReadAsync();
                mediaElement.SetSource(stream, file.ContentType);
                mediaElement.Play();
            
        
        else
        
            mediaElement.Stop();
