Put ArrayList into param JsonObject

Question

i must do i request with Volley Framework. This is a POST request with JSONObject.

I must pass one string and one JSONArray..but how i can?

I start with this

Answer 1

JSONObject can take in Java Objects, try using

Map 

something like this:

    String mUrl;  //initialized somewhere else
    ArrayList mUrlDove;  //initialized somewhere else

    Map jsonParams = new HashMap<>();
    jsonParams.put("url", mUrl);
    jsonParams.put("urlDove", mUrlDove);

    JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, new JSONObject(jsonParams),
            new Response.Listener()
            {
                @Override
                public void onResponse(JSONObject response)
                {
                    Log.d("Volley Response: ", response.toString()); 
                    //do the other stuff you need...
                }
            },
            new Response.ErrorListener()
            {
                @Override
                public void onErrorResponse(VolleyError error)
                {
                    if (null != error.networkResponse)
                    {
                        Log.d(" Volley Error Code: ", "" + error.networkResponse.statusCode);
                       //probably throw an Exception or some MessageEvent
                    }
                }
            });

    requestQueue.add(request);

this works for me with complex objects like

 Map>>

with the most inner objects being Strings and Integers, and the List being initialized as a new ArrayList.

Hope this Helps!
