Json Parsing in Android Application

Question

After completing the XML SAX Parsing now I am working on JSON Parsing in my application. Here I am providing you the Json

Response : {\"menu\": {
                  


        

Answer 1

You can get a JSON object from the response like this (I assume you know how to take care of the response):

String[] file = null;

/* Make a JSON object from your response, yourResponse is a String containing
the whole response */
JSONObject jsonObject = new JSONObject(yourResponse);

/* Your "menu": array from your response */
JSONArray infoArray = jsonObject.getJSONArray("menu"); 

/* If the array contains multiple items, loop it
through the infoArray's size */
for (int i = 0; i < infoArray.length(); i++) {  
        try {    
          //Get the value inside "id"
          file[i] = infoArray.getJSONObject(i).optString("id");                  
            } catch (JSONException e) {
            }       
}

Answer 2

private String jString = "{\"menu\":    {\"id\": \"file\", \"value\": \"File\", \"

They are just creating a string that will look like:

{"menu":    {"id": "file", "value": "File", .. etc.

They use \ because the " char has to be escaped.
