给服务端发送请求后，服务端会返回一连串的数据，这些数据在大部分情况下都是XML格式或者JSON格式。然后JSON相对XML来说解析相对方便一些，所以先说说JSON的解析。

JSON的基本数据格式有这几种：

1.一个JSON对象——JSONObject

{"name":"胡小威" , "age":20 , "male":true}

2.一个JSON数组——JSONArray

[{"name":"胡小威" , "age":20 , "male":true},{"name":"赵小亮" , "age":22 , "male":false}]

3.复杂一点的JSONObject

{"name":"胡小威", "age"=20, "male":true, "address":{"street":"岳麓山南", "city":"长沙","country":"中国"}}

4.复杂一点的JSONArray

[

{"name":"胡小威", "age"=20, "male":true, "address":{"street":"岳麓山南", "city":"长沙","country":"中国"}},

{"name":"赵小亮", "age"=22, "male":false, "address":{"street":"九州港", "city":"珠海","country":"中国"}}

]

5.来个更复杂的，这是我从爱帮公交上扒取的数据

{"buses":{"bus":[{"last_foot_dist":"0","time":"37","segments":{"segment":[{"line_name":"立珊专线(中南大学学生公寓-长沙火车站)","foot_dist":"362","stat_xys":"","stats":"岳麓山南;湖南师大;二里半;岳麓山北;市四医院;华图教育(太平街口);牛耳教育(南阳街口);韭菜园;曙光路口;长岛路口;长沙火车站","end_stat":"长沙火车站","line_xys":"","line_dist":"7535","start_stat":"岳麓山南"}]},"foot_dist":"362","dist":"7897"},{"last_foot_dist":"0","time":"41","segments":{"segment":[{"line_name":"旅1路(科教新村-长沙火车站)","foot_dist":"337","stat_xys":"","stats":"岳麓山南;湖南师大;二里半;岳麓山北;市四医院;华图教育(太平街口);蔡锷中路口;韭菜园;乔庄;曙光路口;长岛路口;五一东村;车站路口;长沙火车站","end_stat":"长沙火车站","line_xys":"","line_dist":"7822","start_stat":"岳麓山南"}]},"foot_dist":"337","dist":"8159"}]}}

接下来是解析部分

一、直接解析

1.{"name":"胡小威" , "age":20 , "male":true}

Java代码  
  1. public void parseJsonObject(String json) {
  2. try {
  3. JSONObject jsonObject = new JSONObject(json);
  4. String name = jsonObject.getString("name");
  5. int age = jsonObject.getInt("age");
  6. boolean male = jsonObject.getBoolean("male");
  7. //接下来该干嘛干嘛
  8. } catch (JSONException e) {
  9. // TODO Auto-generated catch block
  10. e.printStackTrace();
  11. }
  12. }

2.[{"name":"胡小威" , "age":20 , "male":true},{"name":"赵小亮" , "age":22 , "male":false}]

Java代码  
  1. public void parseJSONArray(String json) {
  2. try {

  4. for (int i = 0; i < jsonArray.length(); i++) {
  5. jsonObject = jsonArray.getJSONObject(i);
  6. String name = jsonObject.getString("name");
  7. int age = jsonObject.getInt("age");
  8. boolean male = jsonObject.getBoolean("male");
  9. //接下来该干嘛干嘛
  10. }
  11. } catch (JSONException e) {
  12. // TODO Auto-generated catch block
  13. e.printStackTrace();
  14. }
  15. }

3.{"name":"胡小威", "age"=20, "male":true, "address":{"street":"岳麓山南", "city":"长沙","country":"中国"}}

  12. Person person = new Person(name, age, male, address);
  13. } catch (JSONException e) {
  14. // TODO Auto-generated catch block
  15. e.printStackTrace();
  16. }
  17. }

4.

[

{"name":"胡小威", "age"=20, "male":true, "address":{"street":"岳麓山南", "city":"长沙","country":"中国"}},

{"name":"赵小亮", "age"=22, "male":false, "address":{"street":"九州港", "city":"珠海","country":"中国"}}

]

Java代码  
  1. public void parseJsonArrayPerson(String json) {
  2. List<Person> persons = new ArrayList<Person>();
  3. try {
  4. jsonArray = new JSONArray(json);
  5. for (int i = 0; i < jsonArray.length(); i++) {
  6. jsonObject = jsonArray.getJSONObject(i);
  7. String name = jsonObject.getString("name");
  8. int age = jsonObject.getInt("age");
  9. boolean male = jsonObject.getBoolean("male");
  10. JSONObject addressJSON = jsonObject.getJSONObject("address");
  11. String street = addressJSON.getString("street");
  12. String city = addressJSON.getString("city");
  13. String country = addressJSON.getString("country");
  14. Address address = new Address(street, city, country);
  15. Person person = new Person(name, age, male, address);
  16. persons.add(person);
  17. Log.v("juno", person.toString());
  18. }
  19. } catch (JSONException e) {
  20. // TODO Auto-generated catch block
  21. e.printStackTrace();
  22. }
  23. Log.v("juno", persons.toString());
  24. }

5. {"buses":{"bus":[{"last_foot_dist":"0","time":"37","segments":{"segment":[{"line_name":"立珊专线(中南大学学生公寓-长沙火车站)","foot_dist":"362","stat_xys":"","stats":"岳麓山南;湖南师大;二里半;岳麓山北;市四医院;华图教育(太平街口);牛耳教育(南阳街口);韭菜园;曙光路口;长岛路口;长沙火车站","end_stat":"长沙火车站","line_xys":"","line_dist":"7535","start_stat":"岳麓山南"}]},"foot_dist":"362","dist":"7897"},{"last_foot_dist":"0","time":"41","segments":{"segment":[{"line_name":"旅1路(科教新村-长沙火车站)","foot_dist":"337","stat_xys":"","stats":"岳麓山南;湖南师大;二里半;岳麓山北;市四医院;华图教育(太平街口);蔡锷中路口;韭菜园;乔庄;曙光路口;长岛路口;五一东村;车站路口;长沙火车站","end_stat":"长沙火车站","line_xys":"","line_dist":"7822","start_stat":"岳麓山南"}]},"foot_dist":"337","dist":"8159"}]}}

Java代码  
  1. public List<Salution> parseJSON(String str){
  2. Log.d("返回的JSON数据：", str);
  3. List<Salution> busList = new ArrayList<Salution>();
  4. try {
  5. JSONObject jsonObject = new JSONObject(str);
  6. JSONObject busesJSON = jsonObject.getJSONObject("buses");
  7. JSONArray busJSArray=busesJSON.getJSONArray("bus");
  8. for(int i=0;i<busJSArray.length();i++){
  9. JSONObject busJSObject = busJSArray.getJSONObject(i);
  10. JSONObject segsJSObject=busJSObject.getJSONObject("segments");
  11. JSONArray segJSArray=segsJSObject.getJSONArray("segment");
  12. Salution st=new Salution();
  13. for(int j=0;j<segJSArray.length();j++){
  14. if(j==0){
  15. JSONObject segJSObject = segJSArray.getJSONObject(j);
  16. st.setLine_name1(segJSObject.getString("line_name"));
  17. Log.d("line_name", segJSObject.getString("line_name"));
  18. st.setStats1(segJSObject.getString("stats"));
  19. st.setEnd_stat1(segJSObject.getString("end_stat"));
  20. st.setStart_stat1(segJSObject.getString("start_stat"));
  21. }
  22. if(j==1){
  23. JSONObject segJSObject = segJSArray.getJSONObject(j);
  24. st.setLine_name2(segJSObject.getString("line_name"));
  25. Log.d("line_name", segJSObject.getString("line_name"));
  26. st.setStats2(segJSObject.getString("stats"));
  27. st.setEnd_stat2(segJSObject.getString("end_stat"));
  28. st.setStart_stat2(segJSObject.getString("start_stat"));
  29. }
  30. }
  31. busList.add(st);
  32. }
  33. return busList;
  34. } catch (JSONException e) {
  35. // TODO Auto-generated catch block
  36. e.printStackTrace();
  37. }
  38. return null;
  39. }

这里我只是简单获取了几个我想要的数据。

二、使用JSON类库Gson 来解析JSON

Gson 是 Google 提供的用来在 Java 对象和 JSON 数据之间进行映射的 Java 类库。可以将一个 JSON 字符串转成一个 Java 对象，或者反过来。

首先，从 code.google.com/p/google-gson/downloads/list下载GsonAPI

Java代码  
  1. google-gson-1.7.1-release.zip

再把gson-1.7.jar copy到libs

可以使用两种方法解析

①、通过获取JsonReader对象解析JSON数据：

Java代码  
  1. String jsonData = "[{\"username\":\"arthinking\",\"userId\":001},{\"username\":\"Jason\",\"userId\":002}]";
  2. try{
  3. JsonReader reader = new JsonReader(new StringReader(jsonData));
  4. reader.beginArray();
  5. while(reader.hasNext()){
  6. reader.beginObject();
  7. while(reader.hasNext()){
  8. String tagName = reader.nextName();
  9. if(tagName.equals("username")){
  10. System.out.println(reader.nextString());
  11. }
  12. else if(tagName.equals("userId")){
  13. System.out.println(reader.nextString());
  14. }
  15. }
  16. reader.endObject();
  17. }
  18. reader.endArray();
  19. }
  20. catch(Exception e){
  21. e.printStackTrace();
  22. }

②、通过把JSON数据映射成一个对象，使用Gson对象的fromJson()方法获取一个对象数组进行操作

Java代码  
  1. Type listType = new TypeToken<LinkedList<User>>(){}.getType();
  2. Gson gson = new Gson();
  3. LinkedList<User> users = gson.fromJson(jsonData, listType);
  4. for (Iterator iterator = users.iterator(); iterator.hasNext();) {
  5. User user = (User) iterator.next();
  6. System.out.println(user.getUsername());
  7. System.out.println(user.getUserId());
  8. }

GSON解析复杂的JSON数组

　　在GSON的API中，提供了两个重要的方法：toJson()和fromJson()方法。其中，toJson()方法用来实现将Java对象转换为相应的JSON数据，fromJson()方法则用来实现将JSON数据转换为相应的Java对象。

1.1 toJson()方法

　　toJson()方法用于将Java对象转换为相应的JSON数据，主要有以下几种形式：

　　（1）String toJson(JsonElement jsonElement);

　　（2）String toJson(Object src);

　　（3）String toJson(Object src, Type typeOfSrc);

　　其中，方法（1）用于将JsonElement对象（可以是JsonObject、JsonArray等）转换成JSON数据；方法（2）用于将指定的Object对象序列化成相应的JSON数据；方法（3）用于将指定的Object对象（可以包括泛型类型）序列化成相应的JSON数据。

1.2 fromJson()方法

　　fromJson()方法用于将JSON数据转换为相应的Java对象，主要有以下几种形式：

　　（1） T fromJson(JsonElement json, Class classOfT);

　　（2） T fromJson(JsonElement json, Type typeOfT);

　　（3） T fromJson(JsonReader reader, Type typeOfT);

　　（4） T fromJson(Reader reader, Class classOfT);

　　（5） T fromJson(Reader reader, Type typeOfT);

　　（6） T fromJson(String json, Class classOfT);

　　（7） T fromJson(String json, Type typeOfT);

　　以上的方法用于将不同形式的JSON数据解析成Java对象。 
　　 
下面我将以一个具体的列子来说明通过Gson方式解析复杂的json数据 
1.将要解析的数据如下面的格式

服务的端返回的JSON数据

{"song_list": [{"artist_id": "88","language": "国语","pic_big": "http://musicdata.baidu.com/data2/pic/76dc8dc35a361ef018c2c52befabfb03/267709259/267709259.jpg","pic_small": "http://musicdata.baidu.com/data2/pic/eede55e93e4f0353b1eea0a7627e7be1/267709262/267709262.jpg","country": "内地","area": "0","publishtime": "2015-05-20","album_no": "4","lrclink": "http://musicdata.baidu.com/data2/lrc/ac66a881bd5cb97ad351936606c37495/266097259/266097259.lrc","copy_type": "1","hot": "1314161","all_artist_ting_uid": "2517","resource_type": "0","is_new": "0","rank_change": "0","rank": "1","all_artist_id": "88","style": "流行","del_status": "0","relate_status": "0","toneid": "0","all_rate": "64,128,192,256,320,flac","sound_effect": "0","file_duration": 0,"has_mv_mobile": 0,"versions": "","bitrate_fee": "{\"0\":\"0|0\",\"1\":\"0|0\"}","song_id": "242078437","title": "演员","ting_uid": "2517","author": "薛之谦","album_id": "241838068","album_title": "初学者","is_first_publish": 0,"havehigh": 2,"charge": 0,"has_mv": 0,"learn": 1,"song_source": "web","piao_id": "0","korean_bb_song": "0","resource_type_ext": "0","mv_provider": "0000000000","artist_name": "薛之谦"}],"billboard": {"billboard_type": "2","billboard_no": "1906","update_date": "2016-07-24","billboard_songnum": "587","havemore": 1,"name": "热歌榜","comment": "该榜单是根据百度音乐平台歌曲每周播放量自动生成的数据榜单，统计范围为百度音乐平台上的全部歌曲，每日更新一次","pic_s640": "http://b.hiphotos.baidu.com/ting/pic/item/5d6034a85edf8db1194683910b23dd54574e74df.jpg","pic_s444": "http://d.hiphotos.baidu.com/ting/pic/item/c83d70cf3bc79f3d98ca8e36b8a1cd11728b2988.jpg","pic_s260": "http://a.hiphotos.baidu.com/ting/pic/item/838ba61ea8d3fd1f1326c83c324e251f95ca5f8c.jpg","pic_s210": "http://business.cdn.qianqian.com/qianqian/pic/bos_client_58c1700bf56062108d8d622a95708032.jpg","web_url": "http://music.baidu.com/top/dayhot"},"error_code": 22000
}

2.必须定义如下一些的实体类数据 
注意：在定义实体类是要与服务器返回的json字段要完全一致。 
MusicListResponse.java 
里边定义的是服务端返回的json数据，遇到[……]我用了list集合定义它的类型

public class MusicListResponse {private List<Music> song_list;private BillBoard billboard;private int error_code;public MusicListResponse() {}public MusicListResponse(List<Music> song_list, BillBoard billboard,int error_code) {super();this.song_list = song_list;this.billboard = billboard;this.error_code = error_code;}public List<Music> getSong_list() {return song_list;}public void setSong_list(List<Music> song_list) {this.song_list = song_list;}public BillBoard getBillboard() {return billboard;}public void setBillboard(BillBoard billboard) {this.billboard = billboard;}public int getError_code() {return error_code;}public void setError_code(int error_code) {this.error_code = error_code;}
}

BillBoard.java 
这是BillBoard的实体类，里面定义的是 “billboard”: {……}内的json字段 
声明它们的无参和有参的构造方法，还有它们的get和set方法

public class BillBoard {private int havemore;private String billboard_type;private String billboard_no;private String update_date;private String billboard_songnum;private String name;private String comment;private String pic_s640;private String pic_s444;private String pic_s260;private String pic_s210;private String web_url;public BillBoard() {}public BillBoard(int havemore, String billboard_type, String billboard_no,String update_date, String billboard_songnum, String name,String comment, String pic_s640, String pic_s444, String pic_s260,String pic_s210, String web_url) {super();this.havemore = havemore;this.billboard_type = billboard_type;this.billboard_no = billboard_no;this.update_date = update_date;this.billboard_songnum = billboard_songnum;this.name = name;this.comment = comment;this.pic_s640 = pic_s640;this.pic_s444 = pic_s444;this.pic_s260 = pic_s260;this.pic_s210 = pic_s210;this.web_url = web_url;}public int getHavemore() {return havemore;}public void setHavemore(int havemore) {this.havemore = havemore;}public String getBillboard_type() {return billboard_type;}public void setBillboard_type(String billboard_type) {this.billboard_type = billboard_type;}public String getBillboard_no() {return billboard_no;}public void setBillboard_no(String billboard_no) {this.billboard_no = billboard_no;}public String getUpdate_date() {return update_date;}public void setUpdate_date(String update_date) {this.update_date = update_date;}public String getBillboard_songnum() {return billboard_songnum;}public void setBillboard_songnum(String billboard_songnum) {this.billboard_songnum = billboard_songnum;}public String getName() {return name;}public void setName(String name) {this.name = name;}public String getComment() {return comment;}public void setComment(String comment) {this.comment = comment;}public String getPic_s640() {return pic_s640;}public void setPic_s640(String pic_s640) {this.pic_s640 = pic_s640;}public String getPic_s444() {return pic_s444;}public void setPic_s444(String pic_s444) {this.pic_s444 = pic_s444;}public String getPic_s260() {return pic_s260;}public void setPic_s260(String pic_s260) {this.pic_s260 = pic_s260;}public String getPic_s210() {return pic_s210;}public void setPic_s210(String pic_s210) {this.pic_s210 = pic_s210;}public String getWeb_url() {return web_url;}public void setWeb_url(String web_url) {this.web_url = web_url;}
}

Music.java 
这是Music的实体类，里面定义的是 “song_list”: [{……},{……}……]内的json字段，声明它们的无参和有参的构造方法，还有它们的get和set方法。（要以服务端返回的数据，完全一致）

public class Music {private int file_duration;private int has_mv_mobile;private int is_first_publish;private int havehigh;private int charge;private int has_mv;private int learn;private String

然后具体的实体类定义好了就将解析数据了，下面就是我的解析数据类

public class MainActivity extends Activity {private RequestQueue queue;protected MusicListResponse resp;private private List<Music> musics;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);//发送http请求加载音乐列表数据loadMusics();}/*** 加载所有音乐数据*/private void loadMusics() {//1.创建volley的  RequestQueue queue = Volley.newRequestQueue(this);//2. StringRequestString url = "http://tingapi.tiantian.com/v1/restserver/ting?from=qianqian&version=2.1.0&method=tiantian.ting.billboard.billList&format=json&type=2&offset=0&size=50";StringRequest req = new StringRequest(url, new Listener<String>() {public void onResponse(String response) {//使用gson解析json字符串Gson gson = new Gson();resp = gson.fromJson(response, MusicListResponse.class);musics = resp.getSong_list();}}, new ErrorListener() {public void onErrorResponse(VolleyError error) {Log.e("error", error.getMessage());}});//3. add()queue.add(req);}
