Android音乐播放器（三）轮播图

这是去年大二做的一个简单音乐播放器项目：是尽可能模仿酷狗音乐写的，具体实现的功能如下：

1：启动动画：点击运行程序会出现一个两秒钟的视频，类似酷狗音乐的启动动画一样，非常可观！

2：登录注册界面：输入账号和密码检验信息登录！

3：轮播图：和酷狗音乐的一模一样，在主界面的上方有一个自动循环的轮播图，点击轮播图的每一个图片信息即可进入对应的具体服务，非常具有加分点！

4：音乐唱片的转盘，歌曲同步进度条，以及音乐的暂停/播放/继续/上下曲切换！

5：音乐的搜索实现！

6：视频专栏的播放！

7;个人信息界面的布局实现，如反馈，评分，更多，性别年龄昵称，收藏等！

轮播图代码如下：
