volley接受数据时中文会出现乱码

private void doVolley(){    RequestQueue mRequestQueue = Volley.newRequestQueue(getActivity());

    StringRequest mStringRequest = new StringRequest(            "http://www.baidu.com",            new Response.Listener<String>() {                @Override                public void onResponse(String response) {                    String s = response;                    mWebView.getSettings().setJavaScriptEnabled(true);                    mWebView.getSettings().setDefaultTextEncodingName("utf-8");                    mWebView.loadDataWithBaseURL(null,s,"text/html","utf-8",null);                }            },            new Response.ErrorListener() {                @Override                public void onErrorResponse(VolleyError error) {                    mWebView.loadDataWithBaseURL(null,"失败","text/html","utf-8",null);                }            }    ){//这是重写的方法,源代码默认是外国人用的ISO-8859-1,现在改成utf-8格式

        @Override        protected Response<String> parseNetworkResponse(                NetworkResponse response) {

            try {//jsonObject要和前面的类型一致,此处都是String                String jsonObject = new String(                        new String(response.data, "UTF-8"));                return        Response.success(jsonObject, HttpHeaderParser.parseCacheHeaders(response));            } catch (UnsupportedEncodingException e) {                return Response.error(new ParseError(e));            } catch (Exception je) {                return Response.error(new ParseError(je));            }        }    };    mRequestQueue.add(mStringRequest);
