前言：
RecyclerView 是Android L版本中新添加的一个用来取代ListView的SDK，它的灵活性与可替代性比listview更好.

多说无益，直接看效果图：

首先项目build.gradle中添加下面依赖：

//图片轮播
implementation 'com.youth.banner:banner:1.4.10'
//注解id
implementation 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'
//列表
implementation 'com.android.support:recyclerview-v7:27.+'
//加载图片
implementation 'com.github.bumptech.glide:glide:4.3.1'123456789

注意：studio3.0以下版本implementation 换成compile

1、全部java代码：
