Volley 结合GSON或FastJson用法

自定义GSON类

 public class GsonRequest<T> extends Request<T> {
     private final Gson mGson = new Gson();
     private final Class<T> mClazz;
     private final Listener<T> mListener;
     private final Map<String, String> mHeaders;

     public GsonRequest(String url, Class<T> clazz, Listener<T> listener, ErrorListener errorListener) {
         this(Method.GET, url, clazz, null, listener, errorListener);
     }

     public GsonRequest(int method, String url, Class<T> clazz, Map<String, String> headers,
             Listener<T> listener, ErrorListener errorListener) {
         super(method, url, errorListener);
         this.mClazz = clazz;
         this.mHeaders = headers;
         this.mListener = listener;
     }

     @Override
     public Map<String, String> getHeaders() throws AuthFailureError {
         return mHeaders != null ? mHeaders : super.getHeaders();
     }

     @Override
     protected void deliverResponse(T response) {
         mListener.onResponse(response);
     }

     @Override
     protected Response<T> parseNetworkResponse(NetworkResponse response) {
         try {
             String json = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
             return Response.success(mGson.fromJson(json, mClazz),
                     HttpHeaderParser.parseCacheHeaders(response));
         } catch (UnsupportedEncodingException e) {
             return Response.error(new ParseError(e));
         } catch (JsonSyntaxException e) {
             return Response.error(new ParseError(e));
         }
     }
 }

自定义FastJson类

 public class FastJsonRequest<T> extends Request<T> {
     private final Class<T> mClazz;
     private final Listener<T> mListener;
     private final Map<String, String> mHeaders;

     public FastJsonRequest(String url, Class<T> clazz, Listener<T> listener, ErrorListener errorListener) {
         this(Method.GET, url, clazz, null, listener, errorListener);
     }

     public FastJsonRequest(int method, String url, Class<T> clazz, Map<String, String> headers,
             Listener<T> listener, ErrorListener errorListener) {
         super(method, url, errorListener);
         this.mClazz = clazz;
         this.mHeaders = headers;
         this.mListener = listener;
     }

     @Override
     public Map<String, String> getHeaders() throws AuthFailureError {
         return mHeaders != null ? mHeaders : super.getHeaders();
     }

     @Override
     protected void deliverResponse(T response) {
         mListener.onResponse(response);
     }

     @Override
     protected Response<T> parseNetworkResponse(NetworkResponse response) {
         try {
             String json = new String(response.data, HttpHeaderParser.parseCharset(response.headers));
             return Response.success(JSON.parseObject(json, mClazz),
                     HttpHeaderParser.parseCacheHeaders(response));
         } catch (UnsupportedEncodingException e) {
             return Response.error(new ParseError(e));
         }
     }
 }

                          WeatherInfo weatherInfo = weather.getWeatherinfo();
                           text.setText(text.getText()+weatherInfo.getTime());
                     }
                 }, new Response.ErrorListener() {

Model类

 public class Weather {
     private WeatherInfo weatherinfo;  

     public WeatherInfo getWeatherinfo() {
         return weatherinfo;
     }  

     public void setWeatherinfo(WeatherInfo weatherinfo) {
         this.weatherinfo = weatherinfo;
     }
 }

 public class WeatherInfo {
     private String city;  

     private String temp;  

     private String time;  

     public String getCity() {
         return city;
     }  

     public void setCity(String city) {
         this.city = city;
     }  

     public String getTemp() {
         return temp;
     }  

     public void setTemp(String temp) {
         this.temp = temp;
     }  

     public String getTime() {
         return time;
