使用 Material Components 和 androidX 编译 Android 应用程序时出错

Question

Android 应用突然拒绝构建，返回此错误：

Android 资源链接失败 错误：资源样式/Theme.MaterialComponents.Light.NoActionBar（又名 it.duemilanet.icircle:style/Theme.MaterialComponents.Light.NoActionBar) 没找到。

D:\GitLab\iCircleAndroidRMA\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:1440： 错误：样式属性'attr/colorSecondary（又名 it.duemilanet.icircle:attr/colorSecondary)' 未找到。 错误：资源样式/Widget.Design.BottomSheet.Modal（又名 it.duemilanet.icircle:style/Widget.Design.BottomSheet.Modal）不是 成立。 错误：资源样式/Theme.Design.Light.BottomSheetDialog（又名 it.duemilanet.icircle:style/Theme.Design.Light.BottomSheetDialog）不是 成立。 D:\GitLab\iCircleAndroidRMA\app\build\intermediates\incremental\mergeDebugResources\merged.dir\values\values.xml:3296： 错误：样式属性'attr/bottomSheetStyle（又名 it.duemilanet.icircle:attr/bottomSheetStyle)' 未找到。 错误：链接引用失败。

之前编译还不错，几周前我切换到 androidX 和 material components 主题并启用 jetifier 没有问题

build.gradle：

buildscript {

• 我尝试禁用 Instant Run 并恢复到之前版本的材料库，但无法修复错误。

Answer 1

材料设计文档中引用了几个组件，这些组件尚未在 Android 材料设计库的稳定版本中。尝试改用 alpha 版本。

将以下内容添加到您的build.gradle：

dependencies { 
    ...
    implementation 'com.google.android.material:material:1.2.0-alpha02'
}

Answer 2

从Android Studio 的File 菜单尝试Invalidate Cashes / Restart。
