一个Android下的自动下载歌词的代码（转）

1. 原理是用Baidu音乐搜索的连接，拼参数进去读取歌词。
同理也可以一样读取到音乐文件。
代码不是很难，但是网上基本上看不到这种代码，有的也是不能运行的。
所以我就做个好事吧。

2. 搜索歌词文件的代码：

package com.hyronjs.jiangbiao;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;import java.net.MalformedURLException;import java.net.URL;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();/* * 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(' ', '+');String strUrl = "http://box.zhangmen.baidu.com/x?op=12&title="+ musicName + "$$" + singerName + "$$$$";Log.d("test", strUrl);try {url = new URL(strUrl);} catch (Exception e1) {e1.printStackTrace();}BufferedReader br = null;String s;try {InputStreamReader in = new InputStreamReader(url.openStream());Log.d("the encode is ", in.getEncoding());br = new BufferedReader(in);} catch (IOException e1) {Log.d("tag", "br is null");}try {while ((s = br.readLine()) != null) {sb.append(s + "/r/n");br.close();}} catch (IOException e) {// TODO Auto-generated catch blocke.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";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) {//Sentence sentence = new Sentence(s);gcContent.add(s);}br.close();} catch (IOException e) {e.printStackTrace();}}return gcContent;}}

3. 使用搜索的Active的例子

package com.hyronjs.jiangbiao;import java.util.ArrayList;import android.app.Activity;import android.os.Bundle;import android.widget.TextView;public class GetSongWord extends Activity {private TextView mTextView1; /** Called when the activity is first created. */  private DrawLRC mGameView;       /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);//      Baidu search = new Baidu("love the way you","michael jackson");        SearchLRC search = new SearchLRC("love the way you","");        ArrayList result = search.fetchLyric();        setContentView(R.layout.main);    }}
