我直接展示我的实现思路： 1.接收输入框的输入文字并传到查询方法里。百度音乐盒提供了一个便捷的API可以拿来访问一些音乐资源，开发者通过访问指定格式的url可以拿到返回的数据，这个数据可以是json或者xml，这里面包含了歌曲的信息。完整的API各种访问格式是非常丰富的，参见/liuying1995/p/5704176.html。这里我们只实现查询关键字，得到返回的歌曲列表和百度定义的歌曲的id，然后再使用这个id访问，再从返回的数据中得到歌曲和歌词的地址，接下来就可以顺利完成歌曲的播放和下载了。-------另外，本文中还提供了一个动态显示歌词的自定义view和读取歌词文件的工具类。
String name = etSearch.getText().toString();if (name.length() == 0) {Toast.makeText(this, "请输入歌曲名称", Toast.LENGTH_SHORT).show();} else {Toast.makeText(MainActivity.this,"已开始查询，请耐心等待",Toast.LENGTH_SHORT).show();query2(name);}
2.在查询方法中访问URL并得到返回的json，传入解析json的方法。这里面的url字符串格式参见开头提到的网站，可以看到字符串最后的参数query=我们传入的查询数据。
private void query2(final String title){new Thread(new Runnable() {@Overridepublic void run() {try {HttpURLConnection connection;String finalTitle = URLEncoder.encode(title,"utf-8");URL url = new URL("http://tingapi./v1/restserver/ting?from=webapp_music&method=baidu.ting.search.catalogSug&format=json&callback=&query="+finalTitle);connection = (HttpURLConnection) url.openConnection();connection.setConnectTimeout(60*1000);connection.setReadTimeout(60*1000);connection.connect();BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));String s;if ((s=reader.readLine())!=null)doJson(s);} catch (IOException e) {e.printStackTrace();}}}).start();}
3.在解析方法中最终取得歌曲的名称，艺术家，地址，歌词地址信息，json解析就不具体展开了，然后我把这些数据封装在自定义的Song对象里。（方法中调用了两个方法，分别是获取歌曲地址和歌词地址，在下面会展示，这是因为获取这两个数据需要用得到的歌曲的id再一次访问）。
//解析返回的jsonpublic Song doJson(String json){Song song = null;JSONObject jsonObject = null;list.clear();//清空原有的歌曲数组try {//去掉括号json = json.replace("(","");json = json.replace(")","");jsonObject = new JSONObject(json);JSONArray array = new JSONArray(jsonObject.getString("song"));for (int i=0;i<array.length();i++){JSONObject object = array.getJSONObject(i);String songname = object.getString("songname");String artistname = object.getString("artistname");String songid = object.getString("songid");String adress = getAdress(songid);Song song1 = new Song(songname,artistname,adress,0);song1.setLrcPath(getLrcAdress(songid));list.add(i,song1);Log.v("tag",songname+" "+artistname+" "+songid);//列表更新Message msg = new Message();msg.what = 1;handler.sendMessage(msg);}} catch (JSONException e) {e.printStackTrace();}return song;}public String getAdress(final String songid){new Thread(new Runnable() {@Overridepublic void run() {try {HttpURLConnection connection;//URL url = new URL("/weixin/musicapi.php?q="+finalTitle);URL url = new URL("/data/music/links?songIds="+songid);connection = (HttpURLConnection) url.openConnection();connection.setConnectTimeout(60*1000);connection.setReadTimeout(60*1000);connection.connect();BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));String s;if ((s=reader.readLine())!=null){s = s.replace("\\","");//去掉\\try {JSONObject object = new JSONObject(s);JSONObject object1 = object.getJSONObject("data");JSONArray array = object1.getJSONArray("songList");JSONObject object2 = array.getJSONObject(0);adress = object2.getString("songLink");Log.v("tagadress",adress);} catch (JSONException e) {e.printStackTrace();}}} catch (IOException e) {e.printStackTrace();}}}).start();try {Thread.sleep(500);} catch (InterruptedException e) {e.printStackTrace();}return adress;}//获取歌词地址public String getLrcAdress(final String songid){new Thread(new Runnable() {@Overridepublic void run() {try {HttpURLConnection connection;//URL url = new URL("/weixin/musicapi.php?q="+finalTitle);URL url = new URL("/data/music/links?songIds="+songid);connection = (HttpURLConnection) url.openConnection();connection.setConnectTimeout(60*1000);connection.setReadTimeout(60*1000);connection.connect();BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream()));String s;if ((s=reader.readLine())!=null){s = s.replace("\\","");//去掉\\Log.v("tag","------"+s);try {JSONObject object = new JSONObject(s);JSONObject object1 = object.getJSONObject("data");JSONArray array = object1.getJSONArray("songList");JSONObject object2 = array.getJSONObject(0);LrcAdress = object2.getString("lrcLink");Log.v("tag","888888lrc"+ LrcAdress);} catch (JSONException e) {e.printStackTrace();}}} catch (IOException e) {e.printStackTrace();}}}).start();try {Thread.sleep(500);} catch (InterruptedException e) {e.printStackTrace();}return LrcAdress;}
4.展示歌词的自定义view（转）：这里传入了一个自定义的歌词类，是把每一行歌词作为一个对象，其中有歌词内容和歌词开始时间这两个值。
package com.example.one.newmusicplayer.ui;import android.content.Context;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.graphics.Typeface;import android.util.AttributeSet;import android.widget.TextView;import com.example.one.newmusicplayer.item.LrcOne;import java.util.ArrayList;import java.util.List;/*** Created by lenovo on /10/27.* 显示歌词的自定义view*/public class LrcView extends TextView {private float width; //歌词视图宽度private float height; //歌词视图高度private Paint currentPaint; //当前歌词画笔private Paint notCurrentPaint; //非当前歌词画笔private float textHeight = 45; //每一行高度private float textSize = 35; //每一行非当前文字的大小private int index = 0;//list集合下标private List<LrcOne> list = new ArrayList<>();public LrcView(Context context) {super(context);init();}public LrcView(Context context, AttributeSet attrs) {super(context, attrs);init();}private void init() {setFocusable(true);//设置可对焦//高亮部分currentPaint = new Paint();currentPaint.setAntiAlias(true); //设置抗锯齿，让文字美观饱满currentPaint.setTextAlign(Paint.Align.CENTER);//设置文本对齐方式//非高亮部分notCurrentPaint = new Paint();notCurrentPaint.setAntiAlias(true);notCurrentPaint.setTextAlign(Paint.Align.CENTER);}/*** 绘画歌词*/@Overrideprotected void onDraw(Canvas canvas) {super.onDraw(canvas);if(canvas == null) {return;}//设置字体的大小颜色样式以及绘制出来的画笔currentPaint.setColor(Color.argb(210, 251, 0, 0));notCurrentPaint.setColor(Color.argb(140, 0, 0, 0));currentPaint.setTextSize(40);currentPaint.setTypeface(Typeface.SERIF);notCurrentPaint.setTextSize(textSize);notCurrentPaint.setTypeface(Typeface.DEFAULT);try {setText("");canvas.drawText(list.get(index).getLrcStr(), width / 2, height / 2, currentPaint);float tempY = height / 2;//画出本句之前的句子for(int i = index - 1; i >= 0; i--) {//向上推移tempY = tempY - textHeight;canvas.drawText(list.get(i).getLrcStr(), width / 2, tempY, notCurrentPaint);}tempY = height / 2;//画出本句之后的句子for(int i = index + 1; i < list.size(); i++) {//往下推移tempY = tempY + textHeight;canvas.drawText(list.get(i).getLrcStr(), width / 2, tempY, notCurrentPaint);}} catch (Exception e) {setText("");}}/*** 当view大小改变的时候调用的方法*/@Overrideprotected void onSizeChanged(int w, int h, int oldw, int oldh) {super.onSizeChanged(w, h, oldw, oldh);this.width = w;this.height = h;}public void setIndex(int index) {this.index = index;}public void setmLrcList(List<LrcOne> mLrcList) {this.list = mLrcList;}}
5.读取歌词文件的工具类，读取后封装在一个歌词类的数组里。
package com.example.one.newmusicplayer.tools;import android.util.Log;import android.widget.Toast;import com.example.one.newmusicplayer.item.LrcOne;import java.io.BufferedInputStream;import java.io.BufferedReader;import java.io.BufferedWriter;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;import java.io.OutputStreamWriter;import .HttpURLConnection;import .MalformedURLException;import .URL;import java.nio.charset.Charset;import java.util.ArrayList;import java.util.List;/*** Created by lenovo on /10/27.* 读取歌词并将其拆成一个个歌词类的工具类*/public class LrcDeal {public List<LrcOne> getList() {return list;}private List<LrcOne> list = new ArrayList<>();//读取歌词并返回一个装满歌词对象的list//读取网络歌词文件的方法public List<LrcOne> readIntnetLrc(String path){InputStream inputStream = null;try {URL url = new URL(path);HttpURLConnection connection = (HttpURLConnection) url.openConnection();connection.setConnectTimeout(60*1000);connection.setReadTimeout(60*1000);inputStream = connection.getInputStream();} catch (Exception e) {e.printStackTrace();}StringBuilder stringBuilder = new StringBuilder();//创建一个文件输入流try {//创建一个文件输入流对象BufferedReader br = new BufferedReader(new InputStreamReader(inputStream,"utf-8"));String s = "";while((s = br.readLine()) != null) {s = s.replace("[", "");s = s.replace("]", "@");//分离“@”字符String splitLrcData[] = s.split("@");LrcOne lrcOne = new LrcOne();if(splitLrcData.length > 1) {lrcOne.setLrcStr(splitLrcData[1]);//处理歌词取得歌曲的时间int lrcTime = time2Str(splitLrcData[0]);lrcOne.setLrcTime(lrcTime);//添加进列表数组list.add(lrcOne);}}} 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 list;}//对时间字符串进行处理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;}}
