[android help] JSON String to ListView not happening

I have a JSON String, I am trying to parse and then into ListView, my code does not throw any errors but it is not working either, I am unable to determine where I might be going wrong. Following is my code:

      protected void onPostExecute(String result) {
            super.onPostExecute(result);
            str = result;
            Toast.makeText(getApplicationContext(),""+str, Toast.LENGTH_LONG).show(); // Able to toast the JSON string (str) here. 
            mylist = new ArrayList>();
            map = new HashMap();
            try {
                JSONArray jArray = new JSONArray(str);
                    for (int i = 0; i < jArray.length(); i++) {

                        JSONObject jObject = jArray.getJSONObject(i);


                        j_id = jObject.getString(ID);

                        j_make = jObject.getString(MAKE);

                        j_model = jObject.getString(MODEL);

                        j_version = jObject.getString(VERSION);
                        j_price = jObject.getString(PRICE);
                        j_reg_plc = jObject.getString(PLACE_REG);


                    Toast.makeText(getApplicationContext(),"After assign", Toast.LENGTH_LONG).show();



                    data = "Make: "+ j_make + "\nModel: " + j_model + "\nVersion: " + j_version + "\nPrice: " + j_price
                            + "\nCity: " + j_reg_plc;



                    map.put("car", data); 

                    mylist.add(map); 

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




    //  list = (ListView) findViewById(R.id.listView1);
        Toast.makeText(getApplicationContext(),""+mylist, Toast.LENGTH_LONG).show();
        String[] from = new String[] { "car"};
        int[] to = new int[] { R.id.text1 };
        ListAdapter adapt = new SimpleAdapter(view_cars.this, mylist,R.layout.text_adaptr, from, to);

        list.setAdapter(adapt);


    }

It seems that my for loop is ubruptly exiting, It is not getting executed twice as the length of the array I am recieving from network is two. I have attached the screen shot of the JSON Array I am getting

Please check the code for comments, for detailed information.
