前言：小巫的简、美音乐播放器从5月7号开始开发，之前以为时间很充足，也没有估量整个软件的需求，如果简单实现基本的操作的话，确实可以在一个星期内把一个简单的音乐播放器给开发出来。不过我增加了很多特性，比如歌词的显示，专辑封面的显示，界面的左右切换，倒影效果实现等，让整个音乐播放器添色很多，与我之前想开发出操作简单，界面漂亮的想法一致，这是另我比较开心的。到目前为止实现了以下功能：

第1阶段完成的功能：

好啦，来看看整个软件的全貌吧：

  

  

  

       

             

以上就是简、美音乐播放器的全貌，是不是感觉蛮简美的哈。

下面是实现第二阶段功能的代码：

算了，我直接把整个Activity的代码贴出来，里面的代码也有做相应的修改的。不过你们直接看源码就好了。

2016年补充：这个例子是笔者初学时做的一个Demo，还不是很完善，基于sdk也是比较旧，是基于Android 2.3版本的，现在Android已经更新迭代很多版本的了，无论是代码和sdk都已经不适用，大家学习这个demo的时候，了解开发的思路就行了，网上有很多优秀的开源播放器学习，音乐播放器作为入门练手的项目还是很不错的，这个系列的博文已经很久没更新，有很多错漏的地方，望大家见谅。
