Volley 结合GSON或FastJson用法

自定义GSON类

 1 public class GsonRequest<T> extends Request<T> {

 2     private final Gson mGson = new Gson();

 3     private final Class<T> mClazz;

 4     private final Listener<T> mListener;

 5     private final Map<String, String> mHeaders;

 6 

 7     public GsonRequest(String url, Class<T> clazz, Listener<T> listener, ErrorListener errorListener) {

 8         this(Method.GET, url, clazz, null, listener, errorListener);

 9     }

10 

11     public GsonRequest(int method, String url, Class<T> clazz, Map<String, String> headers,

12             Listener<T> listener, ErrorListener errorListener) {

13         super(method, url, errorListener);

14         this.mClazz = clazz;

15         this.mHeaders = headers;

16         this.mListener = listener;

17     }

18 

19     @Override

20     public Map<String, String> getHeaders() throws AuthFailureError {

21         return mHeaders != null ? mHeaders : super.getHeaders();

22     }

23 

24     @Override

25     protected void deliverResponse(T response) {

26         mListener.onResponse(response);

27     }

28 

29     @Override

30     protected Response<T> parseNetworkResponse(NetworkResponse response) {

31         try {

32             String json = new String(response.data, HttpHeaderParser.parseCharset(response.headers));

33             return Response.success(mGson.fromJson(json, mClazz),

34                     HttpHeaderParser.parseCacheHeaders(response));

35         } catch (UnsupportedEncodingException e) {

36             return Response.error(new ParseError(e));

37         } catch (JsonSyntaxException e) {

38             return Response.error(new ParseError(e));

39         }

40     }

自定义FastJson类

 1 public class FastJsonRequest<T> extends Request<T> { 

 2     private final Class<T> mClazz;

 3     private final Listener<T> mListener;

 4     private final Map<String, String> mHeaders;

 5 

 6     public FastJsonRequest(String url, Class<T> clazz, Listener<T> listener, ErrorListener errorListener) {

 7         this(Method.GET, url, clazz, null, listener, errorListener);

 8     }

 9 

10     public FastJsonRequest(int method, String url, Class<T> clazz, Map<String, String> headers,

11             Listener<T> listener, ErrorListener errorListener) {

12         super(method, url, errorListener);

13         this.mClazz = clazz;

14         this.mHeaders = headers;

15         this.mListener = listener;

16     }

17 

18     @Override

19     public Map<String, String> getHeaders() throws AuthFailureError {

20         return mHeaders != null ? mHeaders : super.getHeaders();

21     }

22 

23     @Override

24     protected void deliverResponse(T response) {

25         mListener.onResponse(response);

26     }

27 

28     @Override

29     protected Response<T> parseNetworkResponse(NetworkResponse response) {

30         try {

31             String json = new String(response.data, HttpHeaderParser.parseCharset(response.headers));

32             return Response.success(JSON.parseObject(json, mClazz),

33                     HttpHeaderParser.parseCacheHeaders(response));

34         } catch (UnsupportedEncodingException e) {

35             return Response.error(new ParseError(e));

36         }
