Android JSON Parsing Example.

The process of parsing JSON in Android is pretty simple, thankfully. We'll be using JSONObject for all the parsing goodness - there are also some other JSON classes, but we'll just go through the basic ones to give you a general idea of how it works.

1. String strJson="your url";  
2.           
3.                String data = "";  
4.                try {  
5.                      // Create the root JSONObject from the JSON string.  
6.                    JSONObject  jsonRootObject = new JSONObject(strJson);  
7.   
8.                    //Get the instance of JSONArray that contains JSONObjects  
9.                     JSONArray jsonArray = jsonRootObject.optJSONArray("Employee");  
10.                      
11.                     //Iterate the jsonArray and print the info of JSONObjects  
12.                     for(int i=0; i < jsonArray.length(); i++){  
13.                         JSONObject jsonObject = jsonArray.getJSONObject(i);  
14.                            
15.                         int id = Integer.parseInt(jsonObject.optString("id").toString());  
16.                         String name = jsonObject.optString("name").toString();  
17.                         float salary = Float.parseFloat(jsonObject.optString("salary").toString());  
18.                            
19.                        }  
20.                     output.setText(data);  
21.                  } catch (JSONException e) 
22.                   {e.printStackTrace();
23.         }
