传递一个krc格式歌词的路径，返回读取并返回解密的字符串

public String krc2lrc(String krc){  try {  // 酷狗音乐歌词文件  File krcfile = new File(krc);  byte[] zip_byte = new byte[(int) krcfile.length()];  FileInputStream fileinstrm = new FileInputStream(krcfile);  byte[] top = new byte[4];  fileinstrm.read(top);  fileinstrm.read(zip_byte);  int j = zip_byte.length;  for (int k = 0; k < j; k++) {  int l = k % 16;  int tmp67_65 = k;  byte[] tmp67_64 = zip_byte;  tmp67_64[tmp67_65] = (byte) (tmp67_64[tmp67_65] ^ miarry[l]);  }  String krc_text = new String(decompress(zip_byte), "utf-8");  krc_text = krc_text.replaceAll("<.*?>", "");//删除krc多余的时间(此时间是单字显示的时间)  krc_text = extractMessageByRegular(krc_text);  System.out.println(krc_text);  } catch (Exception e) {  }
}

使用正则表达式提取中括号中的内容

public static String extractMessageByRegular(String msg){  Pattern p = Pattern.compile("(\\[[^\\]]*\\])");  Matcher m = p.matcher(msg);  while(m.find()){  String str = m.group().substring(1, m.group().length()-1);  try{  String[] split = str.split(",");  String spl = "[" + ms2Date(Long.parseLong(split[0])) + "]";//只截取前面的时间（后面的时间为单字时间，舍弃）  msg = msg.replace(m.group(), spl);  }catch (Exception e) {
//由于标题之类的格式也是以[开头以]结尾，所以此时转换为long会转换异常  }  }  return msg;
}

通过字节读取krc文件

public static byte[] decompress(byte[] data) {  byte[] output = new byte[0];  Inflater decompresser = new Inflater();  decompresser.reset();  decompresser.setInput(data);  ByteArrayOutputStream o = new ByteArrayOutputStream(data.length);  try {  byte[] buf = new byte[1024];  while (!decompresser.finished()) {  int i = decompresser.inflate(buf);  o.write(buf, 0, i);  }  output = o.toByteArray();  } catch (Exception e) {  output = data;  e.printStackTrace();  } finally {  try {  o.close();  } catch (IOException e) {  e.printStackTrace();  }  }  decompresser.end();  return output;
}

格式化时间格式

public static String ms2Date(long ms){DateFormat formatter = new SimpleDateFormat("mm:ss");  Calendar calendar = Calendar.getInstance();  calendar.setTimeInMillis(ms);  return formatter.format(calendar.getTime());
}
