OKHttp二次封装请求数据加RecycycleView展示

依赖：

Okhttp依赖：implementation 'com.squareup.okhttp3:okhttp:3.10.0'

RecyclerView依赖：
compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'

activity_main中：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
