Fetch different photos from json file Android

Question

I am extracting the JSON file from the assets folder inside the device. I want to pull product information and images from my JSON file. I can get information, but I don't know how to get pictures. How can I pull different photos in my JSON file? My photos are now in the drawable folder. Names: "soupexample", "simitexample", "chickenexample" .

  ListView listView ;

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

        listView = findViewById(R.id.listView);

        try {

            JSONObject obj=new JSONObject(LoadFromJsonAssets());
            JSONArray array =obj.getJSONArray("domestic");
            HashMap<String,String> list;
            ArrayList<HashMap<String,String>> arrayList=new ArrayList<>();
            for (int i=0;i<array.length();i++){
                JSONObject o=array.getJSONObject(i);
                String productName=o.getString("productName");
                String productPrice=o.getString("productPrice");
                String productPic=o.getString("productPic");
                list= new HashMap<>();
                list.put("productName",productName);
                list.put("productPrice",productPrice);
                list.put("productPic",productPic);
                arrayList.add(list);
            }
            ListAdapter adapter= new SimpleAdapter(this,arrayList,R.layout.list_view_design,new String[]{"productPic","productName","productPrice"},new int[]{R.id.productPic,R.id.productName,R.id.productPic});
            listView.setAdapter(adapter);
        }catch (JSONException e){
            e.printStackTrace();
        }



    }

    public String LoadFromJsonAssets(){
        String json=null;
        try {
            InputStream in=this.getAssets().open("products.json");
            int size = in.available();
            byte[] bbuffer=new byte[size];
            in.read(bbuffer);
            in.close();
            json=new String(bbuffer,"UTF-8");

        }catch (IOException e){
            e.printStackTrace();
            return null;
        }
        return json;
    }
}

my json file:

{
"domestic": [
   {
     "productId": 1,
     "productName": "Soup",
     "productPrice": "25,00",
     "productPic": "soupexample"
   },
   {
     "productId": 2,
     "productName": "Simit",
     "productPrice": "17,00",
     "productPic": "simitexample"
   },
   {
     "productId": 3,
     "productName": "Chicken",
     "productPrice": "15,00",
     "productPic": "chickenexample"
   }
]
}
