1. 首先在res下创建raw,然后将mp3音乐拷贝到raw下
2. 直接贴代码吧

//开始播放声音public class PlayVoice {    private static MediaPlayer mediaPlayer;    public static void playVoice(Context context){        try {            mediaPlayer= MediaPlayer.create(context, R.raw.opening);            mediaPlayer.start();            mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {                @Override                public void onCompletion(MediaPlayer mp) {                    mediaPlayer.start();                }            });        } catch (Exception e) {            e.printStackTrace();        }    }    //停止播放声音    public  static void stopVoice(){        if(null!=mediaPlayer) {            mediaPlayer.stop();        }    }}
