51 | ## 感谢
52 |
53 | 项目来源自hongyang的代码,在其基础上修改,原代码在:[https://github.com/hongyangAndroid/Android-StickyNavLayout](https://github.com/hongyangAndroid/Android-StickyNavLayout) , 在其基础上修改一些bug,以及支持底部根布局不必必须为ViewPager,以及三个View不比指定id。
54 |
55 | 同时,感谢[@ta893115871](https://github.com/ta893115871) 修改的bug [上下滑动 列表 有时会触发OnItemClick事件 ,几率出现](https://github.com/hongyangAndroid/Android-StickyNavLayout/issues/9)
