OkHttp解析数据，RecyclerView和Glide的加载图片

//首先加依赖
compile 'com.android.support:appcompat-v7:26.0.0-alpha1'（与recyclerview的后面要一致）//recyclerview的依赖
compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'
//glide的依赖
 compile 'com.github.bumptech.glide:glide:4.0.0'
//okhttp的依赖
 compile 'com.squareup.okhttp3:okhttp:3.9.0'
//加权限

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

//主页面
