    DateTime = (TextView)findViewById(R.id.textView1);
    Status = (TextView)findViewById(R.id.textView2);

    JobNo = (EditText) findViewById(R.id.add_JobNo);
    //Status = (EditText) findViewById(R.id.add_Status);
    //DateTime = (EditText) findViewById(R.id.add_Date_Time);

    pDialog.setMessage("Processing Please Wait ...");
    pDialog.setIndeterminate(false);
    pDialog.setCancelable(true);
    pDialog.show();

    }

    @Override

        JSONParser jParser = new JSONParser();
        String flag="S" ;
         ArrayList<BasicNameValuePair> params = new ArrayList<BasicNameValuePair>();
        params.clear();

             params.add(new BasicNameValuePair("JobNo",JobNo.getText().toString()));
             params.add(new BasicNameValuePair("flag",flag));
            //Getting JSON from URL
             JSONObject json = jParser.getJSONFromUrl(url,params);
            return json;

    }

                    Cargo = json.getJSONArray(TAG_CargoTrack);
                    for(int i = 0; i < Cargo.length(); i++){
                    JSONObject c = Cargo.getJSONObject(i);



                    String JobNo = c.getString(TAG_JobNo);
                    String Status = c.getString(TAG_Status);
                    String Datetime = c.getString(TAG_DateTime);


                    // Adding value HashMap key => value

                    HashMap<String, String> map = new HashMap<String, String>();

                    map.put(TAG_JobNo, JobNo);
                    map.put(TAG_Status, Status);
                    map.put(TAG_DateTime, Datetime);

                    CargoTracklist.add(map);
                    list=(ListView)findViewById(R.id.listView1);
                    //SimpleAdapter adapter = new SimpleAdapter(Add_Update_User.this, CargoTracklist,
                    ListAdapter adapter = new SimpleAdapter(Add_Update_User.this, CargoTracklist,
                            R.layout.search,
                            new String[] { TAG_JobNo,TAG_Status, TAG_DateTime }, new int[] {
                                    R.id.user_JobNo_txt,R.id.user_Status_txt, R.id.user_Date_Time_txt });
