Volley JSONArrayRequest with JSONObject as parameter

Question

I need to make a request with a JSONObject as follows:

{
    \'LangIDs\': [1, 2],
    \'GenreIDs\': [4],
    \'LowPrice\': 0,
    \'HighPrice\': 999,
    \'S         


        

Answer 1

I created a custom volley request that accepts a JSONObject as parameter.

CustomJsonArrayRequest.java

 public class CustomJsonArrayRequest extends JsonRequest {

        /**
         * Creates a new request.
         * @param method the HTTP method to use
         * @param url URL to fetch the JSON from
         * @param jsonRequest A {@link JSONObject} to post with the request. Null is allowed and
         *   indicates no parameters will be posted along with request.
         * @param listener Listener to receive the JSON response
         * @param errorListener Error listener, or null to ignore errors.
         */
        public CustomJsonArrayRequest(int method, String url, JSONObject jsonRequest,
                                Listener listener, ErrorListener errorListener) {
            super(method, url, (jsonRequest == null) ? null : jsonRequest.toString(), listener,
                    errorListener);
        }

        @Override
        protected Response parseNetworkResponse(NetworkResponse response) {
            try {
                String jsonString = new String(response.data,
                        HttpHeaderParser.parseCharset(response.headers, PROTOCOL_CHARSET));
                return Response.success(new JSONArray(jsonString),
                        HttpHeaderParser.parseCacheHeaders(response));
            } catch (UnsupportedEncodingException e) {
                return Response.error(new ParseError(e));
            } catch (JSONException je) {
                return Response.error(new ParseError(je));
            }
        }
    }

How to use?

JSONObject body = new JSONObject();
// Your code, e.g. body.put(key, value);
CustomJsonArrayRequest req = new CustomJsonArrayRequest(Request.Method.POST, url, body, success, error);
