        // Retrieve JSON Objects from the given URL address



        jsonobject = JSONfunctions.getJSONfromURL("https://www.googleapis.com/youtube/v3/search?part=id%2Csnippet&q=natok+2015&maxResults=50&key=AIzaSyCojCp66RLS9OY8hOwnW0UWLNdC56z24Os");

            // Locate the array name in JSON
            JSONArray jsonarray = jsonobject.getJSONArray("items");

            for (int i = 0; i < jsonarray.length(); i++) {
                HashMap<String, String> map = new HashMap<String, String>();
                jsonobject = jsonarray.getJSONObject(i);
                // Retrive JSON Objects
                JSONObject jsonObjId = jsonobject.getJSONObject("id");
                map.put("videoId", jsonObjId.getString("videoId"));

                JSONObject jsonObjSnippet = jsonobject.getJSONObject("snippet");
                 map.put("title", jsonObjSnippet.getString("title"));

                //JSONObject jsonObjThumbnail = jsonObjSnippet.getJSONObject("thumbnails");
               // String imgURL = jsonobject.getJSONObject("thumbnails").getString("url"); //use "medium/high" instead of default as required.
                JSONObject jsonObjThumbnail = jsonobject.getJSONObject("thumbnails");
                String imgURL = jsonobject.getJSONObject("default").getString("url");









                // Set the JSON Objects into the array
                arraylist.add(map);
            }
        } catch (JSONException e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }

        // Locate the listview in listview_main.xml
        listview = (ListView) findViewById(R.id.listview);
        // Pass the results into ListViewAdapter.java
        adapter = new ListViewAdapter(MainActivity.this, arraylist);
        // Set the adapter to the ListView
        listview.setAdapter(adapter);
        // Close the progressdialog

to get image URL from the JSON, please use the code: after the line JSONObject jsonObjSnippet = jsonobject.getJSONObject("snippet");

JSONObject jsonObjThumbnail = jsonobject.getJSONObject("thumbnails");
String imgURL = jsonObjThumbnail.getJSONObject("default").getString("url");//use "medium/high" instead of default as required.
map.put("url", imgURL);

UPDATE: you will get imgURL as String; Eg: https://i.ytimg.com/vi/uU-uRElXM3A/default.jpg

I think you forgot to add imageURL to "map",

To parse your json you should first define JSONArray object by doing:

JSONArray jsonArray = new JSONArray(jsonArrayString);

Then you need to loop throughout your json array to build one:

JSONArray jsonArray = jsnobject.getJSONArray("array-key");
for (int i = 0; i < jsonArray.length(); i++) {
        JSONObject newObj = jsonArray.getJSONObject(i);
}

By saying images I guess you mean to the thumbnails, so if you are parsing your json all you should do is get to the items array, and there to snippet and than thumbnails. – Yzgeav Zohar Dec 13 '15 at 14:42
can u please prove a sample for me – Amit Saha Dec 13 '15 at 14:46
