android - 资源$NotFoundException : Unable to find resource ID #0xffffffff using NestedScrollView with Motionlayout

Question

使用 NestedScrollView 时结合 Motionlayout ，我得到上面的书面错误。奇怪的是，这个错误 只会发生 , 当 Nestedscrollview里面有一些项目(Constraintlayout 或 textview、button、edittext 等)和 当我尝试移动 NestedScrollView向上。
使用 ScrollView解决了这个问题，但是滚动不起作用......
BaseXML(用于 MotionLayout)

Answer 1

好的，我已经解决了我的问题。有两个问题:我的颜色和我的布局 ID。
首先，我删除了所有自定义的黑白颜色并使用了 @android:color/white和 @android:color/black .二、我给了每个 布局(constraintlayout，我的 motionlayout，textview 等)自定义 ID。
滚动行为现在有效，我唯一的问题是，我得到 W/MotionLayout: WARNING could not find view id -1而且滚动真的很滞后。即将开通another question对于这个错误。
