Volley 自定义请求，返回GsonRequest，进行封装解

1，Volley 自定义请求，返回GsonRequest，进行封装解

• 创建GsonRequest继承Request

import com.android.volley.NetworkResponse;

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;



public class GsonRequest extends Request{

    private Class clazz;

    private Response.Listener mListener;





    public GsonRequest(String url,Class clazz, Response.Listener mListener,Response.ErrorListener listener) {

        super(Method.GET, url, listener);

        this.clazz = clazz;

        this.mListener = mListener;

    }

    //仿照StringRespnose

    @Override

    protected Response parseNetworkResponse(NetworkResponse response) {

        String parsed;

        try {

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

        } catch (UnsupportedEncodingException e) {

            parsed = new String(response.data);

        }

        //将json字符串解析为javabean

        T t = new Gson().fromJson(parsed, clazz);

        return Response.success(t, HttpHeaderParser.parseCacheHeaders(response));

    }

    @Override

    protected void deliverResponse(T response) {

        mListener.onResponse(response);

    }

}

• 调用进行网络访问返回是Gson格式

queue = Volley.newRequestQueue(this); //进行初始化

//参数1  URL，参2 JAVAbean 参3 成功监听，参4 失败监听

GsonRequest gsonRequest = new GsonRequest<>(Api.TEST, User.class, new Response.Listener() {

    @Override

    public void onResponse(User response) {

        text.setText(response.name);

    }

}, new Response.ErrorListener() {

    @Override

    public void onErrorResponse(VolleyError error) {





    }

});

queue.add(gsonRequest);
