当我传递一个 URL 时，它工作正常（用户单击一个按钮）：

final Intent i = new Intent(MusicService.ACTION_URL);
Uri uri = Uri.parse("http://stream-72.shoutcast.com:80/hot108_mp3_128kbps");
i.setData(uri);
startService(i);

但是当用户单击 ListView 项目时，什么也没有发生：

public List<String> songs = new ArrayList<String>();

protected void onListItemClick(ListView l, View v, int position, long id) {
  playSong(MEDIA_PATH + songs.get(position));
}


private void playSong(String songPath) {
    final Intent i = new Intent(MusicService.ACTION_URL);
    Uri uri = Uri.parse(songPath);
    i.setData(uri);
    startService(i);
}

我已经尝试在其中设置 Toasts MusicService.ACTION_URL，它永远不会仅在 ListView 场景中被调用，但它在第一个按钮单击场景中会被调用。

我什至尝试在 playSong 方法中创建一个本地 MediaPlayer（在服务之外）并且它工作正常，但我希望 MusicService 来处理播放列表项：

mp.setDataSource(songPath);

请告诉我，我做错了什么？如果您需要更多信息，请告诉我。谢谢。

试试下面的代码：

private void playSong(String songPath) {
    final Intent i = new Intent(MusicService.ACTION_URL);
    File file = new File("file://"+songPath);
    Uri uri = Uri.fromFile(file);
    i.setData(uri);
    startService(i);
}
