使用JSON解析

Question

{ 
    "user": { 
     "name": ["bineesh", "Administrator", "binu", "binu", "bijith", "prem"] 
    }, 
    "email": ["[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]", "[email protected]"], 
    "phone": ["7293553814", "12345", "0", "0", "0", "9046567239"] 
} 

我无法分析这种反应，我不能检索数据？

Answer 1

示例代码：

public void parse(String s){   
    try { 
     JSONObject jsonObject = new JSONObject(s); 
     JSONObject namejObj = jsonObject.getJSONObject("user"); 
     JSONArray nameArray = namejObj.getJSONArray("name"); 
     for(int i =0;i<nameArray.length();i++){ 
      Log.i("System out","name : "+nameArray.getString(i).toString()); 
     } 
    } catch (JSONException e) { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 

}

您可以使用以下方法来解析JSON文件

   JSONObject obj = new JSONObject(result); 

       JSONObject objUser = obj.getJSONObject("user"); 
       JSONArray arrUser = objUser.getJSONArray("name"); 
       for(int i=0;i<arrUser.length();i++) 
       { 
        String name = arrUser.getString(i); 
       } 

       JSONArray arrEmail = objUser.getJSONArray("email"); 
       for(int i=0;i<arrEmail.length();i++) 
       { 
        String email = arrEmail.getString(i); 
       } 

       JSONArray arrPhone = objUser.getJSONArray("phone"); 
       for(int i=0;i<arrPhone.length();i++) 
       { 
        String phone = arrPhone.getString(i); 
       }

示例代码：

public class HomeActivity extends ListActivity { 

    /** Called when the activity is first created. */ 
    @SuppressWarnings({ "rawtypes", "unchecked" }) 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     setListAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, this.fetchTwitterPublicTimeline())); 
    } 

    public ArrayList<String> fetchTwitterPublicTimeline() 
    { 
     ArrayList<String> listItems = new ArrayList<String>(); 

     try { 
      URL twitter = new URL(
        "http://twitter.com/statuses/public_timeline.json"); 
      URLConnection tc = twitter.openConnection(); 
      BufferedReader in = new BufferedReader(new InputStreamReader(
        tc.getInputStream())); 

      String line; 
      while ((line = in.readLine()) != null) { 
       JSONArray ja = new JSONArray(line); 

       for (int i = 0; i < ja.length(); i++) { 
        JSONObject jo = (JSONObject) ja.get(i); 
        listItems.add(jo.getString("text")); 
       } 
      } 
     } catch (MalformedURLException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } catch (JSONException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
     return listItems; 
    } 
}
