所需权限：
//okhttp依赖
implementation 'com.squareup.okhttp3:okhttp:3.11.0'
implementation 'com.squareup.okhttp3:logging-interceptor:3.11.0'
// glide加载图片依赖
implementation 'com.github.bumptech.glide:glide:4.8.0'

build.gradle中写入 使用xrecyclerview必须写
configurations.all {
resolutionStrategy.eachDependency { DependencyResolveDetails details ->
def requested = details.requested
if (requested.group == 'com.android.support') {
if (!requested.name.startsWith("multidex")) {
details.useVersion '28.0.0'//根据你的底下appcompat-v7版本
}
}
}
}1.布局
1. 多条目布局
//布局1
//布局2
//布局3
2.主页面
