Adding string before displaying json array

Question

I am new to android development. I managed to populate a listview with a string and a number coming from a JSON array.

I want to add a string (Available Quantity: ) before I display the number.

Can anyone help me with this?

It's being currently displayed as..

French Fries
1

Coke
4

I want to display it as:

Product: Coke

Quantity Available: 4

AllProductsActivity.java

public class AllProductsActivity extends ListActivity {

// Progress Dialog
private ProgressDialog pDialog;

// Creating JSON Parser object
JSONParser jParser = new JSONParser();

ArrayList<HashMap<String, String>> productsList;

// url to get all products list
private static String url_all_products = "http://api.nal.usda.gov/ndb/search/?format=json&q=french%20fries&sort=n&max=250&offset=0&api_key=DEMO_KEY";

// JSON Node names
private static final String TAG_PID = "offset";
private static final String TAG_NAME = "name";

// products JSONArray
JSONArray products = null;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.all_products);

    // Hashmap for ListView
    productsList = new ArrayList<HashMap<String, String>>();

    // Loading products in Background Thread
    new LoadAllProducts().execute();

    // Get listview
    ListView lv = getListView();
}

/**

    protected void onPreExecute() {
        super.onPreExecute();
        pDialog = new ProgressDialog(AllProductsActivity.this);
        pDialog.setMessage("Loading products. Please wait...");
        pDialog.setIndeterminate(false);
        pDialog.setCancelable(false);
        pDialog.show();
    }

    /**

    protected String doInBackground(String... args) {
        // Building Parameters
        List<NameValuePair> params = new ArrayList<NameValuePair>();
        // getting JSON string from URL
        JSONObject json = jParser.makeHttpRequest(url_all_products, "GET", params);

        // Check your log cat for JSON reponse
        Log.d("All Products: ", json.toString());

        try {

            // products found
            // Getting Array of Products
            products = json.getJSONObject("list").getJSONArray("item");

            // looping through All Products
            for (int i = 0; i < products.length(); i++) {
                JSONObject c = products.getJSONObject(i);
                // Storing each json item in variable
                String id = c.getString(TAG_PID);
                String name = c.getString(TAG_NAME);

                // creating new HashMap
                HashMap<String, String> map = new HashMap<String, String>();
                // adding each child node to HashMap key => value

                productsList.add(map);
            }
        }
        catch (JSONException e) {
            e.printStackTrace();
        }

        return null;
    }

            }

    }

Answer 1

you can simple add up string when getting it from json like..

String id = "Quantity Available: "+c.getString(TAG_PID);
String name = "Product: "+c.getString(TAG_NAME);
