Android Motionlayout：Android 资源链接失败
[英]Android Motionlayout: Android resource linking failed
问题描述
I keep getting build errors after a refactor to motionlayout 2.0.0-beta1 (I know it's not the newest version - beta2 produces same errors).
在重构到motionlayout 2.0.0-beta1 后，我不断收到构建错误（我知道这不是最新版本——beta2 会产生相同的错误）。
Here's the stacktrace:这是堆栈跟踪：

There's no indication as to what file produces the error and to my knowledge I don't use any of these attributes anywhere in my project.没有关于哪个文件产生错误的迹象，据我所知，我没有在我的项目中的任何地方使用任何这些属性。

This problem is related to Android Studio 3.6 and ConstraintLayout versions earlier than 2.0.0-beta3 - I've reported the issue here .此问题与 Android Studio 3.6 和早于 2.0.0-beta3 的 ConstraintLayout 版本有关 - 我已在此处报告该问题。 This is fixed in ConstraintLayout 2.0.0-beta3.这在 ConstraintLayout 2.0.0-beta3 中得到修复。
Android Studio 3.5 doesn't produce this error. Android Studio 3.5 不会产生此错误。
To make it work in AS 3.6 beta, upgrade to ConstraintLayout 2.0.0-beta3 or later.要使其在 AS 3.6 beta 中工作，请升级到 ConstraintLayout 2.0.0-beta3 或更高版本。

If even upgrading ConstraintLayout doesn't help, try to add format attribute to your attr declaration in your attrs.xml file.如果即使升级ConstraintLayout也无济于事，请尝试将format属性添加到attrs.xml文件中的attr声明中。
<resources>
<attr name="yourAttrName" format="string" />
</resources>
Choose proper format for your attribute.为您的属性选择正确的格式。

我将 gradle 版本升级到com.android.tools.build:gradle:3.6.0然后遇到了这个问题，只需将 gradle 版本降级到com.android.tools.build:gradle:3.5.3问题就解决了

You would have to do two things:你必须做两件事：
Update your android studio.
更新你的安卓工作室。add Latest dependency implementation
添加最新的依赖实现'androidx.constraintlayout:constraintlayout:2.0.0-rc1'
