自定义Volley的GsonRequest使用

Gson结合Volley类：

package com.example.cuboo.myapplication;

import com.android.volley.NetworkResponse;
import com.android.volley.ParseError;
import com.android.volley.Request;
import com.android.volley.Response;
import com.android.volley.toolbox.HttpHeaderParser;
import com.google.gson.Gson;

import java.io.UnsupportedEncodingException;

import static android.icu.lang.UCharacter.GraphemeClusterBreak.T;

/**

 */

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

    public GsonRequest(int method, String url,Class mClass, Response.Listener listener,Response.ErrorListener errorListener) {
        super(method, url, errorListener);
        this.mListener = listener;
        this.mClass = mClass;
    }
    public GsonRequest(String url,Class mClass, Response.Listener listener, Response.ErrorListener errorListener) {
        this(Method.GET, url, mClass, listener, errorListener);
    }

    @Override
    protected Response parseNetworkResponse(NetworkResponse response) {
        String jsonString;
        try {
            jsonString = new String(response.data,
                    HttpHeaderParser.parseCharset(response.headers));

        } catch (UnsupportedEncodingException e) {
            return Response.error(new ParseError(e));
        }
        return Response.success(mGson.fromJson(jsonString, mClass),
                HttpHeaderParser.parseCacheHeaders(response));
    }

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

数据类：

package com.example.cuboo.myapplication;


public class weather {
    private weatherinfo weatherinfo;

    public weatherinfo getWeatherinfo() {
        return weatherinfo;
    }

    public void setWeatherinfo(weatherinfo weatherinfo) {
        this.weatherinfo = weatherinfo;
    }
}
 
  
 
  
 
  
 
  
package com.example.cuboo.myapplication;

/**
 * Created by cuboo on 2016/10/26.
 */

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;
    }

    public void setTime(String time) {
        this.time = time;
    }
}
 
  
 
  
 使用： 
  
 
  
 
  
    RequestQueue mqueue = Volley.newRequestQueue(this);
        GsonRequest gsonRequest = new GsonRequest
                ("http://www.weather.com.cn/data/sk/101010100.html"
                , weather.class, new Response.Listener() {
            @Override
            public void onResponse(weather s) {
                weatherinfo weatherInfo = s.getWeatherinfo();
                Log.d("TAG", "city is " + weatherInfo.getCity());
                Log.d("TAG", "temp is " + weatherInfo.getTemp());
                Log.d("TAG", "time is " + weatherInfo.getTime());
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError volleyError) {
                Log.e("TAG", volleyError.getMessage(), volleyError);
            }
        });
        mqueue.add(gsonRequest);
