在做mp3播放器的时候写了一个LRC的歌词解析的工具，和大家分享一下，有不足的地方，希望大家指出，测试的歌词

[00:41.66]历史落在赢家之手

[00:44.53]至少我们拥有传说

[00:46.90]谁说败者无法不朽

[00:49.51]

[00:54.46]念头却能让人抬头

[00:56.72]抬头去看去爱去追你心中的梦

[01:01.34]

[01:04.57]此生到尽头你是谁曾怎麽活

[01:56.67]直到人们觉醒自我

[01:59.08]何时不盼不求不等将军或英雄

[02:03.74]

[02:09.42]此生到尽头你是谁曾怎麽活

[02:14.10]他们说就让他们去说

[02:18.84]生命如长风吹过谁的心头

[02:24.15]你想被记住的那个名字将会是什麽

[02:27.95]

[02:49.05]苍空盼飞鸿苍生等英雄

[02:51.17]我们颠沛千年依然还在等候

[02:53.68]失去了土地失去了天空

[02:56.06]自问不能失去什麽

[02:58.00]

[02:59.69]此刻到永久你是谁要怎麽活

[03:04.23]为什麽还在问为什麽

[03:09.04]生命如长风风中谁在问我

[03:14.33]你想被记住的那个名字将会是什麽

[03:19.34]你相信什麽你执着什麽你就是什麽

[03:35.63]

modify at 2014-12-1

在使用过程中发现，不能加载中文歌词，原因是编码问题，现在修改，将文件的输入流一行一行的读出，并且转化成UTF-8，可以解决这个问题。

贴出LrcAnalyzeStart方法：

private void LrcAnalyzeStart() {

try {

BufferedReader br = new BufferedReader(new InputStreamReader(filein, "UTF-8"));

String ContentLine;

while((ContentLine = br.readLine()) != null){

// System.out.println(ContentLine[i]);

LrcAnalyzeLine(ContentLine);

}

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}
