木雨音乐 项目开发（八）最近播放界面

最近播放界面

实现功能：

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
