关键代码

网络请求Volley + Gson

public static void query(String type, String postId, final HttpCallback<SearchResult> callback) {
    String action = "/query";
    Map<String, String> params = new HashMap<>(2);
    params.put("type", type);
    params.put("postid", postId);
    String url = makeUrl(action, params);
    GsonRequest<SearchResult> request = new GsonRequest<SearchResult>(url, SearchResult.class,
            new Response.Listener<SearchResult>() {
                @Override
                public void onResponse(SearchResult searchResult) {
                    callback.onResponse(searchResult);
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError volleyError) {
                    callback.onError(volleyError);
                }
            }) {
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            Map<String, String> headers = new HashMap<>();
            headers.put(HEADER_REFERER, BASE_URL);
            return headers;
        }
    };
    request.setShouldCache(false);
    getRequestQueue().add(request);
}

封装GsonRequest

public class GsonRequest<T> extends Request<T> {
    private Class<T> mClass;
    private Response.Listener<T> mListener;
    private Gson mGson;

    public GsonRequest(int method, String url, Class<T> clazz, Response.Listener<T> listener, Response.ErrorListener errorListener) {
        super(method, url, errorListener);
        mClass = clazz;
        mListener = listener;
        mGson = new Gson();
    }

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

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

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