【中文标题】如何在 Android 中播放在线广播流 url。如何在 android 中播放 .pls 广播流 url【英文标题】：How to play online radio streaming url in Android. How to play .pls radio streaming url in android 【发布时间】：2016-04-28 23:46:37 【问题描述】：我在我的服务器中创建了一个 XML 文件。它包含title 和link 标签。我获取标签并将它们显示为ListView 中的链接。从那里，当用户单击链接时，我想在 Radio Station 应用程序中播放 .pls 文件。
这是我的 XML 文件：
<item>
<title> Kushi FM </title>
<link>http://108.163.197.114:8071/listen.pls</link>
</item>
我不知道如何在下一个活动中播放链接。

【问题讨论】：
【参考方案1】：如果您使用 MediaPlayer 流式传输或普通 MediaPlayer 创建应用程序，我建议您使用 Service。可以轻松处理播放器背景和集中处理。
要在Service中使用媒体播放器，您可以根据您的要求将其与BroadCastReceiver或绑定服务一起使用。如果您保留MediaPlayer相关服务会很好running in foreground 下面的代码我没有处理，请检查给定的链接。
在示例代码中，我使用广播接收器将命令从 Activity 发送到 MediaPlayer 的服务（如播放、暂停、更改曲目等），反之亦然。
现在要获取您从 Activity onItemClickListner 发送的 url，您需要从 Intent 获取。
String url = getIntent().getStringExtra("url");

如果有任何事情请告诉我。
【讨论】：
谢谢，但是当用户在 Listview 中单击 Fm 名称时，下一个 Activity 将自动播放，我们该怎么做？？？ 这是我在 NextActivity 中编写的代码，对吗？意图意图= getIntent();最终字符串 selectedData = intent.getStringExtra("url"); fmname.setText(selectedData); mMediaPlayer = new MediaPlayer();尝试 mMediaPlayer.setDataSource(selectedData); mMediaPlayer.prepareAsync(); mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() public void onPrepared(MediaPlayer mp) mMediaPlayer.start(); );Player 我的回答中的 Activity 将是您在 Player 活动的 onCreate 方法中的 Service_Player 它将从意图中获取 url 数据及其调用 startMediaPlayer 方法将启动播放器
谢谢，我明白了，但我的疑问是在下一个活动中我没有放置任何按钮（如开始或停止）它是一个空的活动，收音机想要在这里播放..但是在你的 Coading 中通过按钮 id 使用 Switch 语句并播放该文件，但我没有使用任何按钮我们该怎么做？ @user1140237
让我们continue this discussion in chat。【参考方案2】：
MediaPlayer mp;
mp=MediaPlayer.create(getApplicationContext(),Uri.parse(url))
//Example url of .pls file http://50.xx.xxx.xx:xx40/)
mp.start();
mp.pause();
mp.release() (or mp.reset() as applicable)
