JSON response not printed properly in android Listview using volley

Question

I have a json response which i printed in a listview.It is printed the values from json but all value not printed correctly.Some json values are printed in wrong place.

JSON Response:

```
[
   {
      "HouseNo":"33333333",
      "AreaName":"ghfhgfhg",
      "Landmark":"",

   },
   {

      "HouseNo":"33333333",
      "AreaName":"gfhgfh",
      "Landmark":"",

   }
]

```

This is the code for fetching the specific value:

  StringRequest stringRequest = new StringRequest(Request.Method.POST,url,
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Log.d(TAG, response.toString());
                        hidePDialog();




                            try {
                                JSONArray jsonarray = new JSONArray(response);
                                for (int i = 0; i < jsonarray.length(); i++) {
                                    JSONObject obj = jsonarray.getJSONObject(i);
                                Customer customer = new Customer();
                                customer.setTitle(obj.getString("HouseNo"));
                                customer.setSerial(obj.getString("AreaName"));
                                customer.setService(obj.getString("Landmark"));

                                customerList.add(customer);

                            }

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

                        // notifying list adapter about data changes
                        // so that it renders the list view with updated data
                         adapter.notifyDataSetChanged();
                                  }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                VolleyLog.d(TAG, "Error: " + error.getMessage());
                hidePDialog();

            }
        })

some response are printed ok; But in place of some response printed printed other response.How to resolve this issue?

Your json parsing code is right.Try to override add() method in adapter class if your adapter extends to ArrayAdapter class.

@Override
    public void add(Customer object) {
        customerList.add(object);
        super.add(object);
    }

This will automatically updates your listview.

And If you are using the BaseAdapter.Then there might be error in Model class or List object used for adapter.

You can use Gson library of google for such conversions

Customer c = new Gson().fromJson(json,new TypeToken<Customer>(){}.getType());
