android解析JSON

要解析的json数据：

[java] view plaincopyprint?

1. {"data":  
2.         {"info":[  
3.                         {"id":"01","name":"张三","年龄":"22","地址":"成都"},  
4.                         {"id":"02","name":"李四","年龄":"23","地址":"北京"},  
5.                         {"id":"03","name":"王五","年龄":"24","地址":"西安"},  
6.                         {"id":"04","name":"赵六","年龄":"25","地址":"上海"},  
7.                         {"id":"05","name":"周七","年龄":"26","地址":"深圳"}  
8.                     ]  
9.         }  
10.     }  

解析json:

[java] view plaincopyprint?

1. public void onCreate(Bundle savedInstanceState) {  
2.         super.onCreate(savedInstanceState);  
3.         setContentView(R.layout.activity_main);  
4.         ListView listview=(ListView) findViewById(R.id.listView1);  
5.         String [] ss=analyticJson(s);  
6.         ArrayAdapter aa=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,ss);    
7.         listview.setAdapter(aa);  
8.     }  
9.   
10.     public String[] analyticJson(String result){  
11.         try {  
12.             String[] ss=new String[5];//为了演示方便让其返回String[]  
13.             JSONObject jsonObject = new JSONObject(result).getJSONObject("data");  
14.             JSONArray jsonArray=jsonObject.getJSONArray("info");  
15.             for(int i=0;i<jsonArray.length();i++){   
16.                 JSONObject jo = (JSONObject)jsonArray.opt(i);  
17.                 ss[i]=jo.getInt("id")+"  "+jo.getString("name")+"  "+jo.getString("地址");  
18.             }  
19.             return ss;  
20.         } catch (JSONException e) {  
21.             e.printStackTrace();  
22.         }  
23.         return null;  
24.     }
