Android第三次作业

1.界面截图

2.关键代码

2.1设置音乐播放器的播放进度

    private static SeekBar sb;

    private static TextView tv_progress;
    private static TextView tv_total;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        tv_progress = (TextView) findViewById(R.id.tv_progress);
        tv_total = (TextView) findViewById(R.id.tv_total);

2.2添加接口的控制类

    class MusicControl extends Binder implements MusicInterface {
        @Override
        public void play() {
            MusicService.this.play();
        }
        @Override
        public void pausePlay() {
            MusicService.this.pausePlay();
        }
        @Override
        public void continuePlay() {
            MusicService.this.continuePlay();
        }
        @Override
        public void seekTo(int progress) {
            MusicService.this.seekTo(progress);
        }
    }　

2.3播放

    public void play() {

        try {

            if(player == null)
            {
                player = new MediaPlayer();
            }　　

2.4暂停

    public void pausePlay() {

        player.pause();
    }

上一首及下一首功能暂未实现
