使用百度的歌词API，如：

http://box.zhangmen.baidu.com/x?op=12&count=1&title=%E6%97%8B%E6%9C%A8$$%E7%8E%8B%E8%8F%B2$$$$

黄色部分为歌曲名和歌手名，输入如上网址，会得到一个对应的xml文件

 

其中的count值为1是说返回的是一个

<lrcid>43150</lrcid>这个值是我们想要的。

http://box.zhangmen.baidu.com/bdlrc/ 这个是百度lrc歌词存放地址

对应歌词地址：http://box.zhangmen.baidu.com/bdlrc/431/43150.lrc

 

对应类：

这个是网上找到的，自己做了一定的修改，开始的时候不能用，两点原因：

1.需要添加<uses-permission android:name="android.permission.INTERNET"></uses-permission>

2.传入汉字，编码问题，返回0
