Looking at Volley's Source:

https://android.googlesource.com/platform/frameworks/volley/+/android-4.3_r0.9/src/com/android/volley/toolbox/

If I am not mistaken, it comes with JsonObjectRequest and StringRequest, but no XMLRequest.

So, you could use StringRequest to get the response as String, and then use any XML marshalling/serializing tool (ex: Simple) to convert it to an Object.

Check out Simple - XML Marshalling tool: http://simple.sourceforge.net/download.php

If you use StringRequest, something like following should do it:

StringRequest request = new StringRequest(Request.Method.GET, url, 
    new Response.Listener() 
    {
        @Override
        public void onResponse(String response) {
          // convert the String response to XML
          // if you use Simple, something like following should do it
            Serializer serializer = new Persister();
            serializer.read(ObjectType.class, response);  
        }
    }, 
    new Response.ErrorListener() 
    {
         @Override
         public void onErrorResponse(VolleyError error) {                                
         // handle error response
       }
    }
);
queue.add(request);

Alternatively, you could create your own XMLRequest class by extending from Request, and use XML Serialization tool (like Simple) to return the Object.

Hope it helps,
