volley接受數據時中文會出現亂碼

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,"失敗","text/html","utf-8",null);
                }
            }
    ){
//這是重寫的方法,源代碼默認是外國人用的ISO-8859-1,如今改爲utf-8格式

        @Override        protected Response<String> parseNetworkResponse(                NetworkResponse response) {            try {//jsonObject要和前面的類型一致,此處都是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);}
