在对 motionlayout 2.0.0-beta1 进行重构后，我不断收到构建错误（我知道它不是最新版本 - beta2 会产生相同的错误）。

这是堆栈跟踪：

没有迹象表明哪个文件会产生错误，据我所知，我在项目的任何地方都没有使用这些属性中的任何一个。

此问题与早于 2.0.0-beta3 的 Android Studio 3.6 和 ConstraintLayout 版本有关 - 我已在此处报告此问题。这在 ConstraintLayout 2.0.0-beta3 中已修复。

Android Studio 3.5 不会产生此错误。

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。

如果即使升级ConstraintLayout也无济于事，请尝试在attrs.xml文件中的attr声明中添加格式属性。

<resources>
    <attr name="yourAttrName" format="string" />
</resources>

为您的属性选择适当的格式。

升级到 constraintlayout:2.0.0-beta4，为我工作，或更高版本。将 android studio 升级到 3.6 后会发生这种情况

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并解决问题

你必须做两件事：

  1. 更新你的安卓工作室。

  2. 添加最新的依赖实现

    'androidx.constraintlayout:constraintlayout:2.0.0-rc1'
