I want to code for android application in which there are three parameters which i want to pass to php-webservice.

I have wrritten following code to pass three parameters to web service

Code:

private void getProductStock(String productStock_StyleID, String productStock_SizeID, String productStock_colorID){
if(cc.isNetAvailable(context)) {
String url = CommonClass.MainWebUrl + CommonClass.WebApi.GET_PRODUCT_STOCK;
Map params = new HashMap();

        params.put("style_id", productStock_StyleID);
        params.put("size_id", productStock_SizeID);
        params.put("color", productStock_colorID);

        fetchProductStockQuantity(ViewBrandsActivity.this, url, params);

        } else {
            CommonClass.showToast(getApplicationContext(), CommonClass.ErrorMessage.Network_Error);
        }
    }


     public void fetchProductStockQuantity(final Activity activity, String url, Map param) {

    Map map = new HashMap();
    map = param;
    cc.showProgressDialog("Fetching stock quantity..", activity);
    CustomRequest customRequest = new CustomRequest(Request.Method.POST,
            url, param, new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject jsonObject) {
            // Log.e("jsonObject", "" + jsonObject.toString());
            handleProductStockDataResponse(jsonObject);
     }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError volleyError) {
            System.out.println("Error In Web : " + volleyError.getMessage());
            cc.cancelProgressDialog(activity);
        }
    }) {
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            HashMap<String, String> headers = new HashMap<String, String>();
            //headers.put("Content-Type", "application/x-www-form-urlencoded");
            return headers;
        }
    };
    int socketTimeout = 100000;//60 seconds - change to what you want
    RetryPolicy policy = new DefaultRetryPolicy(socketTimeout,
            DefaultRetryPolicy.DEFAULT_MAX_RETRIES, DefaultRetryPolicy.DEFAULT_BACKOFF_MULT);
    customRequest.setRetryPolicy(policy);
    // Adding request to request queue
    AppController.getInstance().addToRequestQueue(customRequest, url);


}

this webservice returns a value which i want to display in my android application.
How do I check if the 3 parameters are passed to the webservice?
Please tell me above code is currect or not and also tell me how to show that return value in my android application.
