Android JSON Object Parsing

Question

I have some sample json data with objects only.

{
  "0": {
    "image": null,
    "title": "Government to issue new ₹500 and ₹2,000 notes from Nov 10 ",
    "time": "10:46 pm ",
    "date": "08 Nov ",
    "content": "The government will start issuing the new ₹500 and ₹2,000 currency notes from November 10, said ...",
    "link": "https://full-story.newsinshorts.com/v1/article/f0619b6a-738e-4470-897f-4e5cdad3ea52-1 "
  },
  "1": {
    "image": null,
    "title": "₹1,000, ₹5,000 and ₹10,000 notes were demonetised in 1978 ",
    "time": "10:20 pm ",
    "date": "08 Nov ",
    "content": "The Indian government had demonetised the ₹1,000, ₹5,000 and ₹10,000 currency notes in 1978 ...",
    "link": null
  },
  ...

}

It has more objects than what is visible. How can I proceed with parsing this data?

You can try [this sample](http://stackoverflow.com/questions/22606572/android-json-parsing-of-multiple-jsonobjects-inside-jsonobject), I see it nearly same your json. — NamNH, Nov 09 '16 at 01:37

Why you trying to parse make it as model class using GSON and use that model — Saveen, Nov 09 '16 at 02:29
@Saveen The JSON is perfectly valid. Read the link in the first comment on how to parse. Gson cannot be used — OneCricketeer, Nov 09 '16 at 03:13
if something is being repeated in json object its better to have it inside an jsonarray and run a loop to grab all data inside the pojo. — Sagar Nayak, Nov 09 '16 at 04:53
@AdityaVyas-Lakhan I couldnt understand your solution as I am using volley to parse. The problem is still not solved. Thanks everyone and more answers please. — Joseph Joey, Nov 09 '16 at 13:17
it does not matter you using volley..check answer how to parse — Aditya Vyas-Lakhan, Nov 09 '16 at 14:06

I assume the above JSON is gotten from a given source say web server. This is how I would handle it

   String yourJSON = {
          "0": {
            "image": null,
            "title": "Government to issue new ₹500 and ₹2,000 notes from Nov 10 ",
            "time": "10:46 pm ",
            "date": "08 Nov ",
            "content": "The government will start issuing the new ₹500 and ₹2,000 currency notes from November 10, said ...",
            "link": "https://full-story.newsinshorts.com/v1/article/f0619b6a-738e-4470-897f-4e5cdad3ea52-1 "
          },
          "1": {
            "image": null,
            "title": "₹1,000, ₹5,000 and ₹10,000 notes were demonetised in 1978 ",
            "time": "10:20 pm ",
            "date": "08 Nov ",
            "content": "The Indian government had demonetised the ₹1,000, ₹5,000 and ₹10,000 currency notes in 1978 ...",
            "link": null
          },
          ...

        };

        // create a JSON object to handle the response JSON
        JSONObject yourJSONObject = new JSONObject(yourJSON);

        /*
        *this converts entire JSON object to JSON array since there is no further nesting
        *this can be placed in a loop and the 0 replaced by an incremental variable say "int i"
        */
        JSONArray data = yourJSONObject.getJSONArray(String.valueOf(0));

        // loop through the items in the first JSON array which in this case is only one therefore at index 0
        for (int i = 0; i < data.length(); i++) {
            // create JSON object to hold each item in array
            JSONObject json = null;

            try {
                //Getting json
                json = data.getJSONObject(i);

                String image = json.getString("image");
                String title = json.getString("title");
                String time = json.getString("time");
                String date = json.getString("date");
                String content = json.getString("content");
                String link = json.getString("link");

                // perform action on this specific item


            } catch (JSONException e) {
                e.printStackTrace();
            }
        }

According to the documentation, that method doesn't exist. There are no arrays in that JSON, anyways — OneCricketeer, Nov 09 '16 at 03:06
It does compile since this is an extract of code from one of my working Android projects — Jonathan Kibet, Nov 09 '16 at 03:11
The method signature is `getJSONArray(String name)`, though, not an Integer... As I said, though, there isn't any array in that JSON — OneCricketeer, Nov 09 '16 at 03:15
make sure it is String. Sorry for the misslead. Make it **"0"** or if you are using an incremental variable say **int i** then do **0+""+i** — Jonathan Kibet, Nov 09 '16 at 03:18
@cricket_007 true, as I stated, this will be useful when the response from the server has more levels than what is shown here. Read the comments. Therefore this fix will work in this case and also modifiable for more complex applications — Jonathan Kibet, Nov 09 '16 at 03:20
Feel free to [edit] your post. That still shouldn't work, for the reason I've already explained. It isn't `"0": [` in the data. — OneCricketeer, Nov 09 '16 at 03:21
Thanks, but I already understand how to parse the data. The link in the first comment posted on the question works. — OneCricketeer, Nov 09 '16 at 03:24

Ok ...

Try something like this ... just give you an idea ...

MyObject myObject = null;
JSONObject object = new JSONObject(response);
try{
    myObject = new MyObject();
    int position = 0;
    while(position < 100){
        JSONObject jsonObject = object.getJSONObject(String.valueOf(position));
        String title = jsonObject.getString("title");
        myObject.setTitle(title);

        ...


        position++;
    }
}catch (JSONException e){
    return e.getMessage();
}finally{
    return myObject;
}

Try this way i had same json response and it work for me

class LoadAllStates extends AsyncTask<String, String, ArrayList<String>> {
    private ProgressDialog pDialog;
    private String test;
    private ArrayList<String> statedata;
    private ArrayList<String> idadddata;
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(ShippingAddress.this.getActivity());
        pDialog.setMessage("Please wait..");
        pDialog.setIndeterminate(true);
        pDialog.setCancelable(true);
        pDialog.show();
    }

    protected ArrayList<String> doInBackground(String... args) {
        ServiceHandler sh = new ServiceHandler();
        // Making a request to url and getting response
        statedata = new ArrayList<String>();

        idadddata = new ArrayList<String>();


        String jsonStr = sh.makeServiceCall(GET_ADDRESS_DETAIL, ServiceHandler.GET);
        Log.d("Response: ", "> " + jsonStr);
        if (jsonStr != null) {
            try {

                jsonObj = new JSONObject(jsonStr);
                for (int i = 1; i <= jsonObj.length(); i++) {

                    JSONObject user = jsonObj.getJSONObject(""+i);


                    idaddress=String.valueOf(i);
                    System.out.println("userr"+i);

                    username= (user.has("name")) ? user.getString("name") : null;
                    usermobile= (user.has("mobile_number")) ? user.getString("mobile_number") : null;
                    useraddress= (user.has("address")) ? user.getString("address") : null;
                    userlandmark= (user.has("landmark")) ? user.getString("landmark") : null;
                    usercity= (user.has("city")) ? user.getString("city") : null;
                    userstate= (user.has("state")) ? user.getString("state") : null;
                    userpincode= (user.has("pin_code")) ? user.getString("pin_code") : null;
                    useremail= (user.has("email")) ? user.getString("email") : null;
                    if(username!=null)
                        statedata.add(username+","+usermobile+","+useraddress+","+userlandmark+","+usercity+","+userstate+","+userpincode+","+useremail);

                    idadddata.add(idaddress);
                    Log.i("inner",user.toString());
                }
                System.out.println("WifeBday"+statedata.size());
            } catch (JSONException e) {
                e.printStackTrace();
            }
        } else {
            Log.e("ServiceHandler", "Couldn't get any data from the url");
        }
        return statedata;
    }

    protected void onPostExecute(ArrayList<String> result) {
        super.onPostExecute(result);
        pDialog.dismiss();
    }
}
