1.先添加需要的依赖

<pre style="background-color:#ffffff;color:#000000;font-family:'宋体';font-size:10pt;">compile 'com.squareup.okhttp3:okhttp:3.3.0'
compile 'com.github.bumptech.glide:glide:3.7.0'</pre>
 2.添加网络权限

<pre style="background-color:#ffffff;color:#000000;font-family:'宋体';font-size:10pt;"><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.INTERNET"/>
</pre>
 3.HttPConfig类

<pre style="background-color:#ffffff;color:#000000;font-family:'宋体';font-size:10pt;">package com.bw.lenovo.my_fenlei.http;

/**
 * 接口存放类
 */
public class HttpConfig {
//左侧列表接口
 public static String Left_url = "https://www.zhaoapi.cn/product/getCatagory";
//右侧列表接口
 public static String right_url = "https://www.zhaoapi.cn/product/getProductCatagory";
}
</pre>
 4.根据接口去解析一键解析Bean类（LeftBean）和（RightZiBean)
 5.写okHttp网络请求框架 OkHttpUtils

<pre style="background-color:#ffffff;color:#000000;font-family:'宋体';font-size:10pt;">package com.bw.lenovo.my_fenlei.http;

import android.os.Handler;
import android.os.Message;

import java.io.IOException;
import java.util.Map;
import java.util.Set;

import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.FormBody;
import okhttp3.Interceptor;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

public class OKHttpUtils {

private static OKHttpUtils okHttpUtils = null;
private OnLoadLinstener onLoadLinstener;
