1、显示最近点击播放的歌星并按时间先后排序（当前显示10条，可自行更改）
2、点击列表播放列表歌曲
3、菜单项实现跳转“我喜欢”界面，清空最近播放列表

前面MyLikeMusicListActivity,java和MyMusicListFragment.java中已经设置代码

//保存播放记录    private void savePlayRecord() {        //获取当前正在播放的音乐对象        Mp3Info mp3Info = playService.getMp3Infos().get(playService.getCurrentPosition());        try {            Mp3Info playRecordMp3Info = app.dbUtils.findFirst(Selector.from(Mp3Info.class).where("mp3InfoId", "=", mp3Info.getMp3InfoId()));            if (playRecordMp3Info == null) {                mp3Info.setPlayTime(System.currentTimeMillis());//设置当前播放时间                app.dbUtils.save(mp3Info);            } else {                playRecordMp3Info.setPlayTime(System.currentTimeMillis());                app.dbUtils.update(playRecordMp3Info, "playTime");            }        } catch (DbException e) {            e.printStackTrace();        }    }

PlayRecordListActivity.java最近播放界面代码如下
