```
public final class QuickAdapterHelper

                    
```
用于组合 Adapter 的帮助类，生成一个 ConcatAdapter。
结构如下:
```
    ConcatAdapter
```
｜-----------------------------------------------------------------｜｜｜｜ leadingLoadStateAdapter 或者 BeforeAdapter ｜｜｜｜-----------------------------------------------------------------｜｜｜｜｜｜ contentAdapter（内容）｜｜｜｜｜｜-----------------------------------------------------------------｜｜｜｜ trailingLoadStateAdapter 或者 AfterAdapter ｜｜｜｜-----------------------------------------------------------------｜
使用时，请获取此 Helper 提供的 Adapter：
```
val helper = QuickAdapterHelper.Builder(...).build()

recyclerView.adapter = helper.adapter
```
