1、采用一般方式解释json为对象
1 package com.heimazyh.testjson;
2
3 import org.json.JSONException;
4 import org.json.JSONObject;
5
6 import com.heimazyh.http.Request;
7 import com.heimazyh.http.Response;
8
9 public class DoJson implements Response {
10
11 @Override
12 public void process(Object object) {
13 // TODO Auto-generated method stub
14 if(object != null){
15 String str = (String) object;
16 try {
17 JSONObject jsonObject = new JSONObject(str);
18 int id = jsonObject.getInt("id");
19 System.out.println("id=" + id);
20
21 String name = jsonObject.getString("name");
22 System.out.println("name=" + name);
23
24 String address = jsonObject.getString("address");
25 System.out.println("address=" + address);
26 } catch (JSONException e) {
27 // TODO Auto-generated catch block
28 e.printStackTrace();
29 }
30 }
31
32 }
33
34 @Override
35 public Request getRequest() {
36 // TODO Auto-generated method stub
37 String path = "http://192.168.1.101/android/json/echojson.php";
38 String method="get";
39 Request request = new Request(path,method);
40 return request;
41 }
42
43 }
2、采用一般方式解析json为List
1 package com.heimazyh.testjson;
2
3 import java.util.ArrayList;
4 import java.util.List;
5
6 import org.json.JSONArray;
7 import org.json.JSONException;
8 import org.json.JSONObject;
9
10 import com.heimazyh.domain.Person;
11 import com.heimazyh.http.Request;
12 import com.heimazyh.http.Response;
13
14 public class PersonsJson implements Response {
15
16 @Override
17 public void process(Object object) {
18 // TODO Auto-generated method stub
19 if(object != null){
20 String str = (String) object;
21 try {
22 List<Person> list = new ArrayList<Person>();
23 JSONArray jsonArray = new JSONArray(str);
24 for(int index=0; index < jsonArray.length(); index++){
25 JSONObject jsonObject = jsonArray.getJSONObject(index);
26 Person person = new Person();
27 person.setId(jsonObject.getInt("id"));
28 person.setName(jsonObject.getString("name"));
29 person.setAddress(jsonObject.getString("address"));
30 list.add(person);
31 }
32
33 for(int i=0; i < list.size(); i++){
34 Person person2 = list.get(i);
35 System.out.println(person2.toString());
36 }
37 } catch (Exception e) {
38 // TODO Auto-generated catch block
39 e.printStackTrace();
40 }
41 }
42 }
43
44 @Override
45 public Request getRequest() {
46 // TODO Auto-generated method stub
47 String path = "http://192.168.1.101/android/json/persons.php";
48 String method="get";
49 Request request = new Request(path,method);
50 return request;
51 }
52
53 }
3、采用一般方式解析json为map
1 package com.heimazyh.testjson;
2
3 import java.util.ArrayList;
4 import java.util.HashMap;
5 import java.util.Iterator;
6 import java.util.List;
7 import java.util.Map;
8
9 import org.json.JSONArray;
10 import org.json.JSONObject;
11
12 import android.util.Log;
13
14 import com.heimazyh.http.Request;
15 import com.heimazyh.http.Response;
16
17 public class MapJson implements Response {
18
19 @Override
20 public void process(Object object) {
21 // TODO Auto-generated method stub
22 if(object != null){
23 String str = (String) object;
24 try{
25 List<Map<String, Object>> list = new ArrayList<Map<String, Object>>();
26 JSONObject jsonObject = new JSONObject(str);
27 JSONArray jsonArray = jsonObject.getJSONArray("persons");
28 for(int i=0; i < jsonArray.length(); i++){
29 JSONObject jsonObject2 = jsonArray.getJSONObject(i);
30 Map<String, Object> map = new HashMap<String, Object>();
31 Iterator<String> iterator = jsonObject2.keys();
32 while(iterator.hasNext()){
33 String key = iterator.next();
34 Object value = jsonObject2.get(key);
35 if(key == null){
36 key = "";
37 }
38 map.put(key, value);
39 }
40 list.add(map);
41 }
42
43 Log.i("maptest", list.toString());
44 }catch(Exception e){
45 e.printStackTrace();
46 }
47 }
48
49 }
50
51 @Override
52 public Request getRequest() {
53 // TODO Auto-generated method stub
54 String path = "http://192.168.1.101/android/json/echomap.php";
55 String method="get";
56 Request request = new Request(path,method);
57 return request;
58 }
59
60 }
4、使用gson进行解析
1 package com.heimazyh.testjson;
2
3 import com.google.gson.Gson;
4 import com.heimazyh.domain.Person;
5 import com.heimazyh.http.Request;
6 import com.heimazyh.http.Response;
7
8 public class GsonForPerson implements Response {
9
10 @Override
11 public void process(Object object) {
12 // TODO Auto-generated method stub
13 if(object != null){
14 String str = (String) object;
15 Gson gson = new Gson();
16 Person person = gson.fromJson(str, Person.class);
17 System.out.println(person.toString());
18 System.out.println(person.getId());
19 System.out.println(person.getName());
20 System.out.println(person.getAddress());
21 }
22
23 }
24
25 @Override
26 public Request getRequest() {
27 // TODO Auto-generated method stub
28 String path = "http://192.168.1.100/android/json/echojson.php";
29 String method="get";
30 Request request = new Request(path,method);
31 return request;
32 }
33
34 }
1 package com.heimazyh.testjson;
2
3 import java.lang.reflect.Type;
4 import java.util.List;
5
6 import com.google.gson.Gson;
7 import com.google.gson.reflect.TypeToken;
8 import com.heimazyh.domain.Person;
9 import com.heimazyh.http.Request;
10 import com.heimazyh.http.Response;
11
12 public class GsonForPersons implements Response {
13
14 @Override
15 public void process(Object object) {
16 // TODO Auto-generated method stub
17 if(object != null){
18 String str = (String) object;
19 Gson gson = new Gson();
20 Type type = new TypeToken<List<Person>>(){}.getType();
21 List<Person> persons = gson.fromJson(str, type);
22 for(Person person : persons){
23 System.out.println(person.toString());
24 System.out.println(person.getId());
25 System.out.println(person.getName());
26 System.out.println(person.getAddress());
27 }
28 }
29 }
30
31 @Override
32 public Request getRequest() {
33 // TODO Auto-generated method stub
34 String path = "http://192.168.1.100/android/json/persons.php";
35 String method="get";
36 Request request = new Request(path,method);
37 return request;
38 }
39
40 }
