Android NestedScrollView的子视图忽略第一次单击

概述我在我的片段中使用协调器布局和NestedScrollView来进行折叠工具栏动画.我正在动态地向我的嵌套Scrollview容器添加视图.我已经在NestedScrollView中的视图上实现了onClickListener,但是始终忽略对任何视图的第一次单击.当我再次点击或超过它的工作时.我的 XML代码如下： <?xml version="1.0" encoding="utf-8"?><! 我在我的片段中使用协调器布局和nestedScrollVIEw来进行折叠工具栏动画.我正在动态地向我的嵌套ScrollvIEw容器添加视图.我已经在nestedScrollVIEw中的视图上实现了onClickListener,但是始终忽略对任何视图的第一次单击.当我再次点击或超过它的工作时.我的 XML代码如下：

似乎nestedScrollVIEw正在拦截触摸事件,而不是第一次传递给孩子.
我该如何解决这个问题？

解决方法 我有同样的错误.升级后支持库版本到27.0.1 BUG已经消失.

见：https://developer.android.com/topic/libraries/support-library/revisions.html#27-0-1

After a user scrolls,they cannot click on an item in a RecyclerVIEw.
(AOSP issue 66996774)

看到同一个问题：Android – the item inside RecyclerView can’t be clicked after scroll
