1. 首先在res下建立raw,然後將mp3音樂拷貝到raw下
2. 直接貼程式碼吧

//開始播放聲音
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();
        }
    }
    //停止播放聲音
 

    public  static void stopVoice(){
        if(null!=mediaPlayer) {
            mediaPlayer.stop();
        }
    }
}
