如果我没有错，那么你只需替换这个：

    findViewById(R.id.playOnline).setOnClickListener(this);
    findViewById(R.id.playOnline2).setOnClickListener(this);
    findViewById(R.id.pause).setOnClickListener(this);
    findViewById(R.id.button3).setOnClickListener(this);
    findViewById(R.id.stop).setOnClickListener(this);
如下所示：全局定义所有按钮

Button Play1,Play2,Pause,button2,stop;
并将以下内容添加到
OnCreate（）
：

试试这个

更新：

通过以下方式尝试按钮侦听器：

Play1.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            //Here your code
        }
    });
还有所有的按钮

您的代码问题在这里。您刚刚全局定义了
MediaPlayer
对象，那么为什么您要在
PlayOnlineUrl（）
方法中创建另一个
MediaPlayer
对象呢。您只需添加如下内容：

mediaPlayer = new MediaPlayer();
您的声音是否正在播放。声音正在播放，但暂停、恢复、停止不起作用。我在您的代码中遇到问题，请检查我的新更新答案。我尝试了此方法，但再次暂停、恢复和停止不起作用。sp请给出关于暂停的建议，停止正常工作，谢谢。一个问题也出现了，我按下播放按钮，然后再次按下播放按钮，它再次启动 
mediaPlayer = new MediaPlayer();
