Make a standard request

This lesson describes how to use the common request types that Volley supports:

If your expected response is one of these types, you probably don’t have to implement a custom request. This lesson describes how to use these standard request types. For information on how to implement your own custom request, see Implement a custom request.

Request JSON

Volley provides the following classes for JSON requests:

Both classes are based on the common base class JsonRequest. You use them following the same basic pattern you use for other types of requests. For example, this snippet fetches a JSON feed and displays it as text in the UI:


val url = "http://my-json-feed"

val jsonObjectRequest = JsonObjectRequest(Request.Method.GET, url, null,
        Response.Listener { response ->
            textView.text = "Response: %s".format(response.toString())
        Response.ErrorListener { error ->
            // TODO: Handle error

// Access the RequestQueue through your singleton class.


String url = "http://my-json-feed";

JsonObjectRequest jsonObjectRequest = new JsonObjectRequest
        (Request.Method.GET, url, null, new Response.Listener<JSONObject>() {

    public void onResponse(JSONObject response) {
        textView.setText("Response: " + response.toString());
}, new Response.ErrorListener() {

    public void onErrorResponse(VolleyError error) {
        // TODO: Handle error


// Access the RequestQueue through your singleton class.
