It has been written 100% in Kotlin. ❤️ 重新定义RecyclerView Adapter的封装，追求既简单又实用，结合Kotlin的高级特性，优化代码书写方式，真正做到高内聚低耦合
设计图
- DSL写法，简单易用
- 充分考虑ViewHolder复用逻辑，科学防止触碰事件抖动问题
- 抽象合理，高可复用
- 分包依赖，也可以一次性依赖
- 自带Lifecycle生命周期管理
- 动态扩展，耦合降低到了极致
- 部分真泛型，优化泛型问题
| 名字 | release aar size | 其他 |
|---|---|---|
| Core | 32kb | 核心库目前包含ListAdapter的实现，最基础且最实用的扩展 |
| DataBinding | 22kb | 适配DataBinding布局，适用本项目所有Adapter扩展 |
| Sorted | 10kb | SortedListAdapter扩展实现 |
| Paging | 13kb | PagingListAdapter扩展适配 |
| Diff | 6kb | 适配DiffUtil，目前适用ListAdapter |
| FlexBox | 9kb | 适配FlexBox布局 |
| Selectable | 8kb | 动态扩展单选、多选、最大可选项功能 |
| Expandable | 8kb | 动态扩展可展开功能，支持仅单展开或多展开配置 |
| UI | 17kb | 扩展空布局 |
| Animators | 14kb | 扩展动画，包括布局初加载动画，添加Item动画，更新Item动画等 |
| Filter | 9kb | 按照条件过滤列表子项 |
| 名字 | 优势 | 劣势 | 适合做什么 |
|---|---|---|---|
| ListAdapter | 简单实用，易扩展，ViewHolder复用率高，DSL支持写法优美 | 对于需要排序的列表处理麻烦性能低 | 不考虑排序的一般列表 |
| SortedListAdapter | 排序超级容易 | 侵入性高，需要继承SortedModel实现Model层，目前优化为接口，增加了可使用范围 | 任何需要排序的列表 |
| PagingListAdapter | 自带加载状态，后台计算完成后通知刷新，加载效率高 | 侵入性高，需要Model层继承实现，学习成本高，掌握难度高 | 适合自动加载分页的列表 |
适用范围
| 名字 | ListAdapter | SortedListAdapter | PagingListAdapter |
|---|---|---|---|
| LayoutViewModel | 支持 | 支持 | 支持 |
| BindingViewModel | 支持 | 支持 | 支持 |
如何选择
| 名字 | 功能 | 优势 | 其他 |
|---|---|---|---|
| LayoutViewModel | 加载XML布局 | 灵活，易懂，易用 | |
| BindingViewModel | 加载DataBinding布局 | 省去绑定View的过程，代码逻辑简洁 |
提示：按需依赖哦，没必要全部依赖哦
