     String StrWeb = Webservice.readUrl("http://gorab.ir/map/search.php", null);
     String Temp = "";

     try {
         JSONArray list = new JSONArray(StrWeb);
         maylocationget=new ArrayList<StructTest>();
         maylocationget.clear();
         for (int i = 0; i < list.length(); i++)
         {
             StructTest record=new StructTest();

             JSONObject obj1 = list.getJSONObject(i);
             record.id = obj1.getInt("id");
             record.gid = obj1.getInt("gid");
             record. lat= obj1.getDouble("lat");
             record.longg = obj1.getDouble("long");
             record.title =CodeAndDecode.deCoder64(obj1.getString("title"));
             record.discription =CodeAndDecode.deCoder64( obj1.getString("discription"));
             record.addres = CodeAndDecode.deCoder64(obj1.getString("addrestiping"));


             maylocationget.add(record);
         }

         G.pepelerecord.clear();

Add your gradle dependencies compile 'com.loopj.android:android-async-http:1.4.9' and add code below in your activity. You can find here more about Android Asynchronous Http Client library.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    AsyncHttpClient client = new AsyncHttpClient();

    client.get("your_url", null, new JsonHttpResponseHandler(){
        private ProgressDialog progressCircle;

        @Override
        public void onStart() {
            super.onStart();
            progressCircle = new ProgressDialog(MainActivity.this);
            progressCircle.setCancelable(true);
            progressCircle.setMessage("Wait ...");
            progressCircle.setProgressStyle(ProgressDialog.STYLE_SPINNER);
            progressCircle.show();
        }

        @Override
        public void onFinish() {
            super.onFinish();
            progressCircle.cancel();
        }

        @Override
        public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
            int lengthJSONArray = response.length();
            for (int i = 0; i < lengthJSONArray; i++) {
                try {
                    StructTest record=new StructTest();

                    JSONObject obj1 = response.getJSONObject(i);
                    record.id = obj1.getInt("id");
                    record.gid = obj1.getInt("gid");
                    record. lat= obj1.getDouble("lat");
                    record.longg = obj1.getDouble("long");
                    record.title =CodeAndDecode.deCoder64(obj1.getString("title"));
                    record.discription =CodeAndDecode.deCoder64( obj1.getString("discription"));
                    record.addres = CodeAndDecode.deCoder64(obj1.getString("addrestiping"));
                    maylocationget.add(record);
                } catch (JSONException e) {
                    e.printStackTrace();
                }
            }
            adapter.notifyDataSetChanged();
        }
    });
}
