如果没有本地歌词怎么办？现在来将一下加载在线歌词。好了，还是用那张图。
在实现这个功能的时候，lz尝试过baidu api，歌词迷api，后来选用了歌词迷api，虽然还是资源不全，而且还有很多错误。特别头疼的是有时候歌词居然不分行，解析起来简直难受。
歌词迷api歌词查询地址：[http://geci.me/api/lyric/](()
比如我要查询： [http://geci.me/api/lyric/安静/周杰伦](()
会得到一下json串：
{“count”: 2, “code”: 0, “result”: [{“aid”: 2223011, “artist_id”: 30796, “song”: “u5b89u9759”, “lrc”: “http://s.geci.me/lrc/257/25700/2570058.lrc”, “sid”: 2570058}, {“aid”: 2336033, “artist_id”: 30796, “song”: “u5b89u9759”, “lrc”: “http://s.geci.me/lrc/272/27282/2728244.lrc”, “sid”: 2728244}]}
很容易发现里面的歌词文件，然后缓冲到本地（SweetMusicPlayer/Lryics）下，再按本地加载的方式就行了。
捋一捋，我们加载歌词文件要经过以下步骤。
1）通过地址查询出歌词的地址。（这里楼主用URLConnection）
2）通过歌词地址缓冲歌词文件。（这里楼主用URLConnection）
3）加载缓冲好的歌词文件。
上面说的看起来还是比较容易，楼主自己写了个demo,是一个[Java](()工程，发现没啥问题，正常加载歌词文件。
等到[Android](()上，第一步就跪了。发现URLConnection的getInputStream()抛出一个io异常，简直要命，折腾了半天才发现是因为带了[http://geci.me/api/lyric/安静/周杰伦](()中文路径。由于默认是gbk，网络传输为utf-8,所以要把中文转码，URLEncoder.encode(str,“utf-8”)；即可。
到了第2步，问题又出现了，歌词乱码。解决办法，用字符流操作比较合适，还要注意同一编码。
