使用百度的歌词API，如：

http://box.zhangmen.baidu.com/x?op=12&count=1&title=%E6%97%8B%E6%9C%A8 $$%E7%8E%8B%E8%8F%B2 $$$$

黄色部分为歌曲名和歌手名，输入如上网址，会得到一个对应的xml文件

其中的count值为1是说返回的是一个

<lrcid>43150</lrcid>这个值是我们想要的。

http://box.zhangmen.baidu.com/bdlrc/ 这个是百度lrc歌词存放地址

对应歌词地址：http://box.zhangmen.baidu.com/bdlrc/431/43150.lrc

对应类：

package com.android.music.play; import java.io.BufferedReader; import java.io.IOException; import java.io.InputStream; import java.io.InputStreamReader; import java.io.UnsupportedEncodingException; import java.net.HttpURLConnection; import java.net.MalformedURLException; import java.net.URL; import java.net.URLEncoder; import java.util.ArrayList; import android.util.Log; public class SearchLRC { private URL url; public static final String DEFAULT_LOCAL = "GB2312"; StringBuffer sb = new StringBuffer(); private boolean findNumber = false; /* * 初期化，根据参数取得lrc的地址 */ public SearchLRC(String musicName, String singerName) { // 将空格替换成+号 //musicName = musicName.replace(' ', '+'); //singerName = singerName.replace(' ', '+'); //传进来的如果是汉字，那么就要进行编码转化 try { musicName = URLEncoder.encode(musicName, "utf-8"); singerName = URLEncoder.encode(singerName, "utf-8"); } catch (UnsupportedEncodingException e2) { // TODO Auto-generated catch block e2.printStackTrace(); } // String strUrl = "http://box.zhangmen.baidu.com/x?op=12&title=" // + musicName + "$$" + singerName + "$$$$"; String strUrl = "http://box.zhangmen.baidu.com/x?op=12&count=1&title=" + musicName + "$$"+ singerName +"$$$$"; Log.d("test", strUrl); try { url = new URL(strUrl); Log.d("SearchLRC===============","url = "+url); } catch (Exception e1) { e1.printStackTrace(); } BufferedReader br = null; String s; try { HttpURLConnection httpConn = (HttpURLConnection)url.openConnection(); //InputStream in = httpConn.getInputStream(); httpConn.connect(); InputStreamReader inReader = new InputStreamReader(httpConn.getInputStream()); //InputStreamReader in = new InputStreamReader(url.openStream()); Log.d("the encode is ", inReader.getEncoding()); br = new BufferedReader(inReader); } catch (IOException e1) { e1.printStackTrace(); Log.d("tag", "br is null"); } try { while ((s = br.readLine()) != null) { Log.d("SearchLRC","s = "+s); sb.append(s + "/r/n"); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }finally{ try { br.close(); } catch (IOException e) { e.printStackTrace(); } } } /* * 根据lrc的地址，读取lrc文件流 * 生成歌词的ArryList * 每句歌词是一个String */ public ArrayList fetchLyric() { int begin = 0, end = 0, number = 0;// number=0表示暂无歌词 String strid = ""; begin = sb.indexOf("<lrcid>"); Log.d("test", "sb = " + sb); if (begin != -1) { end = sb.indexOf("</lrcid>", begin); strid = sb.substring(begin + 7, end); number = Integer.parseInt(strid); } String geciURL = "http://box.zhangmen.baidu.com/bdlrc/" + number / 100 + "/" + number + ".lrc"; SetFindLRC(number); Log.d("test", "geciURL = " + geciURL); ArrayList gcContent =new ArrayList(); String s = new String(); try { url = new URL(geciURL); } catch (MalformedURLException e2) { e2.printStackTrace(); } BufferedReader br = null; try { br = new BufferedReader(new InputStreamReader(url.openStream(), "GB2312")); } catch (IOException e1) { e1.printStackTrace(); } if (br == null) { System.out.print("stream is null"); } else { try { while ((s = br.readLine()) != null) { gcContent.add(s); // Log.d("SearchLRC","s = "+s); } br.close(); } catch (IOException e) { e.printStackTrace(); } } return gcContent; } private void SetFindLRC(int number) { if(number == 0) findNumber = false; else findNumber = true; } public boolean GetFindLRC(){ return findNumber; } }

这个是网上找到的，自己做了一定的修改，开始的时候不能用，两点原因：

1.需要添加<uses-permission android:name="android.permission.INTERNET"></uses-permission>

2.传入汉字，编码问题，返回0
