在一份书面的使用MediaPlayer播放音乐, http://blog.csdn.net/huweigoodboy/article/details/39862773。假设没有本地歌词怎么办?如今来将一下载入在线歌词。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。尽管还是资源不全。并且还有非常多错误。
特别头疼的是有时候歌词竟然不分行。解析起来简直难受。
歌词迷api歌词查询地址:http://geci.me/api/lyric/
比方我要查询: 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": "\u5b89\u9759", "lrc": "http://s.geci.me/lrc/257/25700/2570058.lrc", "sid": 2570058}, {"aid": 2336033, "artist_id": 30796, "song": "\u5b89\u9759", "lrc": "http://s.geci.me/lrc/272/27282/2728244.lrc", "sid": 2728244}]}
非常easy发现里面的歌词文件。然后缓冲到本地(SweetMusicPlayer/Lryics)下,再按本地载入的方式即可了。
捋一捋,我们载入歌词文件要经过下面步骤。
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)载入缓冲好的歌词文件。
上面说的看起来还是比較easy,楼主自己写了个demo,是一个javaproject,发现没啥问题。正常载入歌词文件。
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由于带了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");就可以。
到了第2步,问题又出现了,歌词乱码。
解决的方法,用字符流操作比較合适,还要注意同一编码。
