Android JsonObjectRequest超时错误，但StringRequest工作正常

我有一个android应用程序，它向REST服务（ASP.NETMVC）请求一个JSON对象。我用截击来做这个

执行此操作的代码：

RequestQueue requestQueue = Volley.newRequestQueue(getActivity().getApplicationContext());
JsonObjectRequest request = new JsonObjectRequest (
    Request.Method.GET,
    "http://192.168.1.253:8090/MyController/MyAction?myParameter=5B1C084B-EFE1-4292-BAF4-A2C30126171D",
    null,
    new Response.Listener<JSONObject>() {
        @Override
        public void onResponse(JSONObject response) {
            Toast.makeText(getActivity(), "OK!" + response.toString(), Toast.LENGTH_SHORT).show();
            mProgressDialog.dismiss();
        }
    },
    new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            if (error.networkResponse != null) {
                Toast.makeText(getActivity(), "Error Response code: " + error.networkResponse.statusCode, Toast.LENGTH_SHORT).show();
            } else {
                Toast.makeText(getActivity(), "Error: " + error.toString(), Toast.LENGTH_SHORT).show();
            }
            mProgressDialog.dismiss();
        }
    });
    requestQueue.add(request);
    mProgressDialog = ProgressDialog.show(getActivity(), "My App", "Searching");

我遗漏了什么吗？

那个url看起来不是很restful…你的监听器应该是

监听器，而不是
监听器
凌乱中字符串和JSON请求对象的区别是内容类型
“application/JSON；charset=UTF-8”
@njzk2我已经更正了代码。我发帖的时候是我的错。
