Resources$NotFoundException: 无法使用带 Motionlayout 的 NestedScrollView 找到资源 ID #0xffffffff
Resources$NotFoundException: Unable to find resource ID #0xffffffff using NestedScrollView with Motionlayout
当结合使用 NestedScrollView 和 Motionlayout 时，我得到上面的书面错误。奇怪的是，这个错误 只会发生 ，当 Nestedscrollview 中有一些项目时（Constraintlayout或 textview、button、edittext 等）AND 当我尝试移动 NestedScrollView起来。
使用 ScrollView 解决了这个问题，但是滚动不起作用...

图片（有ScrollView，但是Scrolling不起作用）
- 展开
- 已崩溃
好的，我的问题已经解决了。有两个问题：我的颜色和布局 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。其次，我给了 EVERY 布局（constraintlayout、我的 motionlayout、textview 等）自定义 ID。
滚动行为现在有效，我遇到的唯一问题是，我得到 W/MotionLayout: WARNING could not find view id -1 并且滚动真的很慢。将为此错误打开 。
当结合使用 NestedScrollView 和 Motionlayout 时，我得到上面的书面错误。奇怪的是，这个错误 只会发生 ，当 Nestedscrollview 中有一些项目时（Constraintlayout或 textview、button、edittext 等）AND 当我尝试移动 NestedScrollView起来。
