[00:43.83]而你嫣然的一笑如含苞待放
[00:48.30]你的美一缕飘散
[00:50.77]去到我去不了的地方
[02:23.97][00:55.77]
[03:01.92][02:25.63][00:56.90]天正在等烟雨

前面“[ ]”中的数字表示其后歌词的开始时间。例如，“[01:50.25]色白花青的景已跃然于碗底”表示在1分50.25秒时，歌词内容是“色白花青的景已跃 然于碗底”。
还有一种形式是“[03:01.92][02:25.63][00:56.90]天正在等烟雨”这种形式常用于赋格部分(俗称：歌曲的高潮部分)，它表示 在 03:01.92, 02:25.63, 00:56.90 时的歌词都是“天正在等烟雨”。

实现思路：
定义一个类，timelrc，用来存放每一句歌词的内容和时间，每当播放的歌曲的时间改变时，即显示播放的seekbar改变时，刷新歌词RefreshLRC(int)，并将取得的歌词的getLrcString()显示到应用程序中。
使用方法：
在音乐播放的activity界面，获取当前播放歌曲的path，歌词路径。
privatevoidgetLrcPath(Stringpath){
Log.d(TAG,"path="+path);
if(path!=null){
path=path.substring(0,path.lastIndexOf(".")).concat(".lrc");
Filefile=newFile(path);
lrcService.ReadLRC(file);
}
}
通过该函数的调用，如上类会将歌词存储起来。
当播放时间改变时，调用lrcService.RefreshLRC(current); 刷新
在播放界面显示正在播放的歌词内容
public void setLRCText(String lrcString,boolean changeLine) {
if(changeLine){
flipperLrc.showNext();
}
playlrcText.setText(lrcString);
}
