Pass parameters to volley with the PUT method

Question

I'm using this simple code :

JsonObjectRequest req = new JsonObjectRequest(Request.Method.PUT, url, null, new Response.Listener<JSONObject>() {
    @Override
    public void onResponse(JSONObject response) {
        delegate.postNotificationSucced();
    }
}, new Response.ErrorListener() {
    @Override
    public void onErrorResponse(VolleyError error) {
        VolleyLog.d(TAG, "Error: " + error.getMessage());
        Log.d(TAG, ""+error.getMessage()+","+error.toString());
        delegate.postNotificationFailed((APIErrors) error);
    }
}){
    @Override
    public Map<String, String> getParams() throws AuthFailureError {
        Map<String,String> headers = new HashMap<String, String>();
        headers.put("Content-Type","application/x-www-form-urlencoded");
        headers.put("state", Boolean.toString(isChecked));
        return headers;
    }

    @Override
    protected VolleyError parseNetworkError(VolleyError volleyError){
        APIErrors error = null;

        if(volleyError.networkResponse != null && volleyError.networkResponse.data != null){
            error = new APIErrors(new String(volleyError.networkResponse.data));
        }
        return error;
    }
};

When I use the Request.Method.GET or POST instead of PUT, the getParams() method is called but not with the PUT method. My problem is that my API requires a PUT method.

How can I pass my parameters using the PUT method.

Edit :

With the PUT method the getHeaders() method is called, so can I pass my arguments through it ?

Solution :

In my case I solved the problem changing my JsonObjecRequest to StringRequest like suggested by @ishmaelMakitla. And now I pass inside getParams().

I noticed that you are not using the response object for anything - so perhaps change the request from JsonObjectRequest to a StringRequest - remember that you then need to change Response.Listener() to Response.Listener() and the onResponse(JSONObject response) to onResponse(String response)....shout if you need further help. I hope this leads to some workable solution.

The reason is that with JsonObjectRequest, parameters must be pass through the third parameters of the constructor

jsonRequest - A JSONObject to post with the request. Null is allowed and indicates no parameters will be posted along with request.

you can read the doc for more informations.

Cool - by the way, I have created a quick Gist for you that you can "plug-and-play" in your code and let me know if it helps. The Gist is here - you can use the code in the Gist to replace your code above (maybe comment it out) - test it and let me know if it helps. — ishmaelMakitla
You previous comment my problem with JsonObjectRequest we must pass our parameter with the third argument of the JsonObjectRequest constructor, with StringRequest the getParams method is call — panic
Please explain what you mean by "we must pass our parameter with the third argument of the JsonObjectRequest constructor" - does changing to StringReuest solve your getParams problem? — ishmaelMakitla

Since you are not using the response object for anything - you should change the request from JsonObjectRequest to a StringRequest - remember that you then need to change Response.Listener<JSONObject>() to Response.Listener<String>() and the onResponse(JSONObject response) to onResponse(String response).... here is StringRequest Gist I created - you can simply "plug-and-play" in your code and replace the JsonObjectRequest code.
