如果没有本地歌词怎么办？现在来将一下加载在线歌词。好了，还是用那张图。
在实现这个功能的时候，lz尝试过baidu api，歌词迷api，后来选用了歌词迷api，虽然还是资源不全，而且还有很多错误。特别头疼的是有时候歌词居然不分行，解析起来简直难受。
歌词迷api歌词查询地址：http://geci.me/api/lyric/
比如我要查询： http://geci.me/api/lyric/安静/周杰伦
会得到一下json串：
{"count": 2, "code": 0, "result": [{"aid": 2223011, "artist_id": 30796, "song": "\u5b89\u9759", "lrc": "http://s.geci.me/lrc/257/25700/2570058.lrc", "sid": 2570058}, {"aid": 2336033, "artist_id": 30796, "song": "\u5b89\u9759", "lrc": "http://s.geci.me/lrc/272/27282/2728244.lrc", "sid": 2728244}]}
很容易发现里面的歌词文件，然后缓冲到本地（SweetMusicPlayer/Lryics）下，再按本地加载的方式就行了。
捋一捋，我们加载歌词文件要经过以下步骤。
1）通过地址查询出歌词的地址。（这里楼主用URLConnection）
2）通过歌词地址缓冲歌词文件。（这里楼主用URLConnection）
3）加载缓冲好的歌词文件。
上面说的看起来还是比较容易，楼主自己写了个demo,是一个Java工程，发现没啥问题，正常加载歌词文件。
等到Android上，第一步就跪了。发现URLConnection的getInputStream()抛出一个io异常，简直要命，折腾了半天才发现是因为带了http://geci.me/api/lyric/安静/周杰伦中文路径。由于默认是gbk，网络传输为utf-8,所以要把中文转码，URLEncoder.encode(str,"utf-8")；即可。
到了第2步，问题又出现了，歌词乱码。解决办法，用字符流操作比较合适，还要注意同一编码。

LrcProcess 类，用来保存处理下载后的文件
public class LrcProcess {private List<LrcContent> lrcList;//List集合存放歌词内容对象private LrcContent mLrcContent;//声明一个歌词内容对象/*** 无参构造函数用来实例化对象*/public LrcProcess() {mLrcContent = new LrcContent();lrcList = new ArrayList<LrcContent>();}/*** 读取歌词* @param path* @return*/public String readLRC(String path) {//定义一个StringBuilder对象，用来存放歌词内容StringBuilder stringBuilder = new StringBuilder();File f = new File(path.replace(".mp3", ".lrc"));try {//创建一个文件输入流对象FileInputStream fis = new FileInputStream(f);InputStreamReader isr = new InputStreamReader(fis, "utf-8");BufferedReader br = new BufferedReader(isr);String s = "";while((s = br.readLine()) != null) {//替换字符s = s.replace("[", "");s = s.replace("]", "@");//分离“@”字符String splitLrcData[] = s.split("@");if(splitLrcData.length > 1) {Log.i("INFO", splitLrcData[1]+"歌词");mLrcContent.setLrcStr(splitLrcData[1]);Log.i("INFO", splitLrcData[0]+"时间");//处理歌词取得歌曲的时间int lrcTime = time2Str(splitLrcData[0]);mLrcContent.setLrcTime(lrcTime);//添加进列表数组lrcList.add(mLrcContent);//新创建歌词内容对象mLrcContent = new LrcContent();}}} catch (FileNotFoundException e) {e.printStackTrace();stringBuilder.append("木有歌词文件，赶紧去下载！...");} catch (IOException e) {e.printStackTrace();stringBuilder.append("木有读取到歌词哦！");}return stringBuilder.toString();}/*** 解析歌词时间* 歌词内容格式如下：* [00:02.32]陈奕迅* [00:03.43]好久不见* [00:05.22]歌词制作 王涛* @param timeStr* @return*/public int time2Str(String timeStr) {timeStr = timeStr.replace(":", ".");timeStr = timeStr.replace(".", "@");String timeData[] = timeStr.split("@");//将时间分隔成字符串数组//分离出分、秒并转换为整型int minute = Integer.parseInt(timeData[0]);int second = Integer.parseInt(timeData[1]);int millisecond = Integer.parseInt(timeData[2]);//计算上一行与下一行的时间转换为毫秒数int currentTime = (minute * 60 + second) * 1000 + millisecond * 10;return currentTime;}public List<LrcContent> getLrcList() {return lrcList;}
Mainactivity 大概调用方法
public class MainActivity extends Activity {//好久不见 青花private String mMusicName="夜曲";//陈奕迅 周传雄private String mMusicAutor="周杰伦";@SuppressLint("SdCardPath")protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);new Thread(){public void run() { String lrcURL = OnlineLrcUtil.getLrcURL(mMusicName, mMusicAutor);Log.i("INFO", lrcURL+"lrcURL");//开始缓存歌词boolean b = OnlineLrcUtil.wrtieContentFromUrl(lrcURL, OnlineLrcUtil.getLrcPath(mMusicName, mMusicAutor));Log.i("INFO", "缓存歌词"+b);Log.i("INFO", OnlineLrcUtil.getLrcPath(mMusicName, mMusicAutor)+"地址");LrcProcess lrcP=new LrcProcess();lrcP.readLRC(OnlineLrcUtil.getLrcPath(mMusicName, mMusicAutor));Log.i("INFO", "歌词"+lrcP.getLrcList().size());};}.start();}
