Iterating through json array with appended json string in android after json as response from url using volley

Here is the working solution: Using GOOGLE GSON (Open source jar)

import java.io.IOException;import com.google.gson.Gson;import com.google.gson.GsonBuilder;     public class JsonToJava {            public static void main(String[] args) throws IOException {                try{                    String json = "<YOUR_JSON>";                    Gson gson = new GsonBuilder().create();                    VendorInfo vInfo = gson.fromJson(json, VendorInfo.class);                           System.out.println(vInfo.getVendorName());                              } catch(Exception ex) {                    ex.printStackTrace();                }            }        }

Create classes for Vendor and Product

public class Vendor {    public String vendor_name;    public String vendor_description;    public String vendor_slug;    public String vendor_logo;    public String contact_number;    public String getName() {        return vendor_name;    }}public class Product {    public String name;    public long price;    public String image;    public String getName() {        return name;    }}

VendorInfo is the JSON object form:

import java.util.Map;public class VendorInfo {    public Vendor[] vendor;    public Map<Integer, Product> products;    public String getVendorName() {        return vendor[0].getName();    }    public Product getProduct() {        System.out.println(products.size());        return products.get(25);    }}

You can add your getters for Vendor, Product and VendorInfo. You are done! You will get all the data.

To get your products data , you need to use Iterator

   JSONObject jProducts = jsonObject            .optJSONObject("products");    try {        if (jProducts                .length() > 0) {            Iterator<String> p_keys = jProducts                    .keys();            while (p_keys                    .hasNext()) {                String keyProduct = p_keys                        .next();                JSONObject jP = jProducts                        .optJSONObject(keyProduct);                if (jP != null) {                    Log.e("Products",                            jP.toString());                }            }        }    } catch (Exception e) { // TODO:        // handle        // exception    }

you can try with this

JSONObject jsono = null;    try {        jsono = new JSONObject(response);        JSONObject productObject = jsono.getJSONObject("products");        Iterator<String> keys = productObject.keys();        while (keys.hasNext())        {            // get the key            String key = keys.next();            // get the value            JSONObject value = productObject.getJSONObject(key);            //get seprate objects            String name = value.getString("name");            String image = value.getString("image");            Log.i(TAG,name+"-"+image);         }        }        catch (JSONException e) {        e.printStackTrace();    }
