Android解析JSON响应

首先贴上JSON响应数据，我们要解析的就是这段数据：

[
  {
    "phone": [
      "12345678",
      "87654321"
    ],
    "name": "路飞",
    "age": 17,
    "address": {
      "country": "japan",
      "province": "sakura"
    },
    "married": false
  },
  {
    "phone": [
      "123345378",
      "8354321"
    ],
    "name": "樱木",
    "age": 18,
    "address": {
      "country": "china",
      "province": "jiangsu"
    },
    "married": false
  },
  {
    "phone": [
      "22225678",
      "44444444"
    ],
    "name": "悟空",
    "age": 100,
    "address": {
      "country": "china",
      "province": "那美克星"
    },
    "married": false
  }
]

然后贴源代码：

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class MainActivity extends Activity {

    private TextView textView;
    private List<Person> persons;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        try {
            StringBuffer sb = new StringBuffer();
            String url = "http://*********/test/testFunc";//请求数据的url
            String body = getContent(url);
            JSONArray array = new JSONArray(body);
            persons = new ArrayList<Person>();
            String result = null;
            for(int i=0;i<array.length();i++){
                JSONObject obj = array.getJSONObject(i);
                Person p = new Person();                
                
                p.setName(obj.get("name").toString());
                
                p.setMarried(obj.getBoolean("married"));
                
                p.setAge(obj.getInt("age"));
                //read phoneNumber
                JSONArray phoneArray = obj.getJSONArray("phone");
                String[] phoneStr = new String[phoneArray.length()];
                for(int j=0;j<phoneArray.length();j++){
                    phoneStr[j] = phoneArray.getString(j);
                }                
                p.setPhone(phoneStr);
                //read AddressObject
                Address addressTemp = new Address();
                JSONObject addressObj = obj.getJSONObject("address");
                addressTemp.setCountry(addressObj.getString("country"));
                addressTemp.setProvince(addressObj.getString("province"));
                p.setAddress(addressTemp);
                
                persons.add(p);
                
            }
            textView = (TextView)findViewById(R.id.textview);
            for(int i=0;i<array.length();i++){
                result += persons.get(i).toString();
            }
            textView.setText(result);
            
        } catch (Exception e) {
        }
    }
    
    
    private String getContent(String url) throws Exception{
        StringBuilder sb = new StringBuilder();
        HttpClient client = new DefaultHttpClient();
        HttpParams httpParams = client.getParams();
        HttpConnectionParams.setConnectionTimeout(httpParams, 3000);
        HttpConnectionParams.setSoTimeout(httpParams, 5000);
        HttpResponse response = client.execute(new HttpGet(url));
        HttpEntity entity = response.getEntity();
        if( null != entity ){
            BufferedReader reader = new BufferedReader(new InputStreamReader(entity.getContent()));
            String line = null;
            while(null != (line = reader.readLine())){
                sb.append(line+"\n");
            }
            reader.close();
        }
        return sb.toString();
    }
}

记得加网络权限：

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

然后贴实体类：

public class Person {
    private String name;
    private Integer age;
    private Boolean married;
    private String[] phone;
    private Address address;
    public Person() {
        super();
    }
    public Person(String name, Integer age, Boolean married, String[] phone,
            Address address) {
        super();
        this.name = name;
        this.age = age;
        this.married = married;
        this.phone = phone;
        this.address = address;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    public Boolean getMarried() {
        return married;
    }
    public void setMarried(Boolean married) {
        this.married = married;
    }
    public String[] getPhone() {
        return phone;
    }
    public void setPhone(String[] phone) {
        this.phone = phone;
    }
    public Address getAddress() {
        return address;
    }
    public void setAddress(Address address) {
        this.address = address;
    }
    @Override
    public String toString() {
        String phoneStr = "";
        for(int i=0;i<phone.length;i++){
            phoneStr += phone[i]+".";
        }
        return "name:"+name+";age:"+age+";married:"+married+";phone:"+phoneStr+";address:'country="+address.getCountry()+",province="+address.getProvince()+"';\n";
    }
    
}

public class Address {
    private String country;
    private String province;
    public Address(String country, String province) {
        super();
        this.country = country;
        this.province = province;
    }
    public Address() {
        super();
    }
    public String getCountry() {
        return country;
    }
    public void setCountry(String country) {
        this.country = country;
    }
    public String getProvince() {
        return province;
    }
    public void setProvince(String province) {
        this.province = province;
    }
    
}
