需求场景：有个头部，悬停部，下方左右滑动切换内容，再下拉头部内容再次出现，大概是这样
网上有很多这样的源码，我的是参考鸿洋大神的，要原稿说明的请自行百度鸿洋大神的
一、TopicStickyNavLayout ：自定义LinearLayout控件，主要是根据当前滑动的位置处理事件分发

}}上面是我项目中的代码，拷过去有些不需要的删除掉好了。极大可能需要修改为你项目的地方：
1.onInterceptTouchEvent()方法中的if(mInnerScrollView instanceof PullToRefreshListView){}这里的代码改为你项目中用到的类似listview的控件，至于可以参考我的
2.getCurrentScrollView()方法中if(a instanceof NewTopicPagerAdapter){}修改为你的
二、在values文件夹下新建ids_sticky_nav_layout.xml
<?xml version="1.0" encoding="utf-8"?><resources> <item name="id_stickynavlayout_topview" type="id"/> <item name="id_stickynavlayout_viewpager" type="id"/> <item name="id_stickynavlayout_indicator" type="id"/> <item name="id_stickynavlayout_innerscrollview" type="id"/> <item name="id_stickynavlayout_descriptionview" type="id"/></resources>注：如果已经有类似ids的文件，直接放里面就行
三、布局中进行使用
