Volley封装

Volley.jar下载

在Application初始化 Volley queues=Volley.newRequestQueue(appContext); 

并返回RequestQueue 对象

public static RequestQueue getHttpQueues(){
return queues;
}

import android.content.Context;

import com.android.volley.Response.ErrorListener;
import com.android.volley.Response.Listener;
import com.android.volley.VolleyError;
importpublic abstract class VolleyInterface {
    public Context context;
    public static Listener<ResultModel> mListener;
    public static ErrorListener mErrorListener;
    
    public VolleyInterface(Context context,Listener<ResultModel> lisener,ErrorListener errorLisener){
        this.context=context;
        mListener=lisener;
        mErrorListener=errorLisener;
    }
    
    public Listener<ResultModel> loadingListener(){
        mListener=new Listener<ResultModel>() {

            @Override
            public void onResponse(ResultModel resultModel) { 
                onMySuccess(resultModel);
            }
        };
        return mListener;
    }
    
    public ErrorListener errorListener(){
        mErrorListener=new ErrorListener() {

            @Override
            public void onErrorResponse(VolleyError volleyError) {
                OnMyError(volleyError);
            }
        };
        return mErrorListener;
    }
    
    public abstract void onMySuccess(ResultModel resultModel);
    public abstract void OnMyError(VolleyError volleyError);
    
}

VolleyRequest类

import java.util.Map;

import android.content.Context;

import com.android.volley.Request.Method;
importimportpublic class VolleyRequest {
    private static FastJsonRequest<ResultModel> fastJsonRequest;
    public static Context context;
    public static void RequestGet(Context mContext,String url,String tag,VolleyInterface vif){
        FandDaApplication.getHttpQueues().cancelAll(tag);
        fastJsonRequest=new FastJsonRequest<ResultModel>(url, ResultModel.class, vif.loadingListener(), vif.errorListener()); 
        fastJsonRequest.setTag(tag);
        FandDaApplication.getHttpQueues().add(fastJsonRequest);
        //调用会引发com.android.volley.NoConnectionError: java.io.InterruptedIOException错误，原因是volley已经调用过了
        //FandDaApplication.getHttpQueues().start();
    }
    
    
    public static void RequestPost(Context context,String url,Map<String,String> map,String tag,VolleyInterface vif){
        FandDaApplication.getHttpQueues().cancelAll(tag);
        fastJsonRequest=new FastJsonRequest<ResultModel>(Method.POST,url, ResultModel.class, map,vif.loadingListener(), vif.errorListener()); 
        fastJsonRequest.setTag(tag);
        FandDaApplication.getHttpQueues().add(fastJsonRequest);
        //调用会引发com.android.volley.NoConnectionError: java.io.InterruptedIOException错误，原因是volley已经调用过了
        //FandDaApplication.getHttpQueues().start(); 
    }
    
    
}

 使用方式

String url=new BroadcastAPI().getBroadcastList(0,"",0,"",page,pageSize);
                VolleyRequest.RequestGet(context, url, "NEWINVILIST", 
                        new VolleyInterface(context,VolleyInterface.mListener,VolleyInterface.mErrorListener) { 
                    @Override
                    public void onMySuccess(ResultModel resultModel) { 
                         if(ResultApi.isCode(resultModel)){
                             list =JSON.parseArray(resultModel.getResult().toString(), BroadcastDetailsModel.class);
                                //如果用户刷新数据则清空原来缓存记录，为了保证数据统一性
                                BroadcastTable.getInstance(context).deleteAllData(BroadcastTable.newNumber);
                                if (mType == 1) { 
                                    adapter.addItemTop(list);
                                } else {
