60 | recyclerView.addItemDecoration(itemDecoration); 61 | ``` 62 | 63 | * ItemDecorationFactory.StickyDividerBuilder 粘性头部 64 | 65 | ``` 66 | itemDecoration = new ItemDecorationFactory.StickyDividerBuilder() 67 | .dividerHeight(2) 68 | .dividerColor(Color.parseColor("#D8D8D8")) 69 | .callback(new StickyDividerCallback() { 70 | @Override 71 | public GroupData getGroupData(int position) { 72 | //生成GroupData 73 | return data; 74 | } 75 | @Override 76 | public View getStickyHeaderView(int position) { 77 | //...生成headerView 78 | return headerView; 79 | } 80 | }).build(recyclerView); 81 | recyclerView.addItemDecoration(itemDecoration); 82 | ``` 83 | 84 | 其中如果是粘性头部，需要自己生成GroupData和自定义View的设置，GroupData需要设置，**分组标题，在分组中的位置以及该分组的长度**；至于如何实现，需要根据数据格式定义不同的逻辑，可以参照[demo中的实现逻辑去获取](https://github.com/arvinljw/ItemDecorationHelper/blob/master/app/src/main/java/net/arvin/itemdecorationhelper/sample/LinearActivity.java)，该类的getItemDecoration方法。 85 | 86 | **对于分割线没啥说的，可以设置分割线的颜色和大小。** 87 | 88 | #### 默认头部 89 | 90 | 其中对于显示分组头部，有一个默认实现DefaultHeaderCallBack，只需要重写分组数据即可。例如： 91 | 92 | ``` 93 | headerCallBack = new DefaultHeaderCallBack(this) { 94 | @Override 95 | public GroupData getGroupData(int position) { 96 | //生成GroupData 97 | return data; 98 | } 99 | }; 100 | ``` 101 | 102 | *注意如果添加在Adapter中添加了emptyView，那么这个时候其实是没有数据项的，所以在getGroupData方法中返回null即可* 103 | 104 | #### 头部点击事件 105 | 106 | 为头部增加点击事件，其中回调中的position是当前header所在的item的实际位置。 107 | 108 | ``` 109 | ((BaseStickyDividerItemDecoration) itemDecoration).setOnHeaderClickListener(new OnHeaderClickListener() { 110 | @Override 111 | public void onHeaderClicked(int position) { 112 | //TODO 113 | } 114 | }); 115 | ``` 116 | 117 | *注意：在界面被销毁时，调用headerCallBack的onDestroy方法，避免内存泄漏。* 118 | 119 | #### 代码混淆 120 | 121 | ``` 122 | -keep class net.arvin.itemdecorationhelper.**{*;} 123 | ``` 124 | 125 | ### TODO 126 | 127 | * 优化实现方式 128 | 129 | ### 原理 130 | 131 | 继承ItemDecoration，然后重写`getItemOffsets`和`onDraw`方法，实现分割线的绘制，通过重写`onDrawOver`实现粘性头部。 132 | 133 | 原理很简单，就是首先让itemView在你需要的方向偏移，例如left，top，right，botton；然后再在`onDraw`或者`onDrawOver`方法中获取到当前屏幕的view，并根据他们的位置，按照偏移的逻辑在相应区域绘制即可。借用一张图，感谢[【Android】RecyclerView：打造悬浮效果](https://www.jianshu.com/p/b335b620af39)。 134 | 135 | ![](https://upload-images.jianshu.io/upload_images/1638147-9e8a8158237c005c.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/548) 136 | 137 | 很直观，可以看到不同内容绘制在不同层次，位置重合的话，上层会覆盖下层的内容。 138 | 139 | 具体的实现全是根据这个逻辑计算绘制。其中为了保持平分内容，将分割线拆分，如图：感谢[RecyclerView的 GridItemDecoration等分itemView](https://blog.csdn.net/qq_27192795/article/details/80563487) 140 | 141 | ![](https://upload-images.jianshu.io/upload_images/3157525-0c77a946eb7278c6.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 142 | 143 | 具体的难点就在这两个位置。 144 | 145 | 至于粘性头部，核心逻辑就是对数据的分组以及头部的偏移计算和绘制。也是万变不离其中。具体的实现请参考源码，含有一定的注释。 146 | 147 | ### 感谢 148 | 149 | [RecyclerView 悬浮/粘性头部——StickyHeaderDecoration](https://blog.csdn.net/qian520ao/article/details/76167193) 150 | 151 | [【Android】RecyclerView：打造悬浮效果](https://www.jianshu.com/p/b335b620af39) 152 | 153 | [RecyclerView的 GridItemDecoration等分itemView](https://blog.csdn.net/qq_27192795/article/details/80563487) 154 | 155 | 在实现过程中参考了很多文章，如果没有注明来源的，麻烦指出来，会直接加上引用来源的。 156 | 157 | ## License 158 | 159 | ``` 160 | Copyright 2018 arvinljw 161 | 162 | Licensed under the Apache License, Version 2.0 (the "License");
