17 | 18 | ## 效果图   19 | 20 | 1. swipe and drag.拖曳 + 滑动删除 21 | 2. drag. 拖曳 + 首个 item 固定 22 | 23 | PointRefreshPointRefresh 24 | 25 | ## 1. 基础讲解 26 | 27 | 这次主要是把 RecyclerView 比较常用的基本的点，在这里集中整理一下。从这篇文章主要梳理以下几点： 28 | 29 | * 优雅的实现：item 点击事件 & item 长点击事件 30 | * RecyclerView 添加 divider 的标准姿势 31 | * RecyclerView 实现 item 的拖曳排序和滑动删除 32 | * 拖曳排序时，限制首个 item 固定的实现 33 | 34 | 详解介绍请看本项目对应的讲解文章： 35 | **[RecyclerView 梳理：点击&长按事件、分割线、拖曳排序、滑动删除](https://juejin.im/post/5a320ffcf265da43200342a3)** 36 | 37 | 38 | ## 2. 解决 RecyclerView 复用错乱 之 优雅方式 39 | 40 | 当 RcyclerView 中存在 CheckBox 或 EditText 时，因为复用机制的存在，会在滚动时造成数据混乱。 41 | 虽然网上流传的有多种方法来解决，但都比较繁琐或存在一定缺陷。 42 | 这里给大家提供一种比较优雅而合理的方式来解决复用错乱的问题： 43 | 44 | [![reuse disorder](https://github.com/OCNYang/RecyclerViewEvent/blob/master/docs/recyclervieweventreuse_disorder.gif?raw=true)](https://cdn.jsdelivr.net/gh/ocnyang/gallery@master/github/recyclervieweventreuse_disorder.gif) 45 | [图片显示失败？点击查看](https://cdn.jsdelivr.net/gh/ocnyang/gallery@master/github/recyclervieweventreuse_disorder.gif) 46 | 47 | 方法详情和讲解请看[源码](https://github.com/OCNYang/RecyclerViewEvent/blob/master/app/src/main/java/com/ocnyang/recyclerviewevent/reuse_disorder/EleganceMethodActivity.kt) 48 | 49 | ## 3. 使用 `notifyItemChanged(int position, @Nullable Object payload)` 定向刷新 50 | 51 | PointRefresh 52 | 53 | > 仔细观察效果图，会发现：非定向刷新时条目会有闪动；定向刷新不会有闪动 54 | 55 | 具体查看源码说明：[NotifyItemAdapter.onBindViewHolder(holder: NotifyItemViewHolder, position: Int, payloads: MutableList)](https://github.com/OCNYang/RecyclerViewEvent/blob/master/app/src/main/java/com/ocnyang/recyclerviewevent/notify_item/NotifyItemActivity.kt) 56 | 57 | ## 4. 使用 DiffUtil 实现局部刷新 58 | DiffUtil 59 | 60 | 具体查看源码说明：[Activity](https://github.com/OCNYang/RecyclerViewEvent/blob/master/app/src/main/java/com/ocnyang/recyclerviewevent/diff_util/DiffUtilActivity.kt) 61 | [AdapterDiffCallback](https://github.com/OCNYang/RecyclerViewEvent/blob/master/app/src/main/java/com/ocnyang/recyclerviewevent/diff_util/AdapterDiffCallback.kt) 62 | 63 | ## 5. 使用 Paging 3 分页加载 64 | Paging3 65 | 66 | 具体查看源码说明：[paging3 相关代码](https://github.com/OCNYang/RecyclerViewEvent/blob/master/app/src/main/java/com/ocnyang/recyclerviewevent/paging3) 67 | 68 | ## 6. ConcatAdapter 实现多个不同的 Adapter 合并成一个 69 | 70 | ConcatAdapter 71 | 72 | 使用方式： 73 | ```java 74 | recyclerView.adapter = ConcatAdapter(mHeaderAdapter, mAdapter, mFooterAdapter) 75 | ``` 76 | 77 | * 可以使不同的 Adapter (不同数据、不同布局) 合并成一个 Adapter 设置给 RecyclerView 显示； 78 | * 功能有点类似多 ItemViewType 的 Adapter，不同的是每个 Adapter 是从上到下按顺序显示的，不能混排 79 | * 您可能使用过 `ViewHolder.getAdapterPosition` 来获得 Adapter 中某个 ViewHolder 的位置。现在，因为我们合并了多个 Adapter，作为代替，您需要调用 `ViewHolder.getBindingAdapterPosition ()`。 80 | -------------------------------------------------------------------------------- /app/.gitignore:
