无法为 org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler 类型的 object 获取未知 属性 'androidx'
Could not get unknown property 'androidx' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler
我正在尝试借助以下 YouTube 视频构建位置跟踪器应用程序。
“https://www.youtube.com/watch?v=17HqLBkuX-E”
在 build.gradle 模块中,我替换了视频中的 CardView 和 recyclerview 行,因为它们用红色下划线表示 'change according to androix'。这些是我用于 cardview 和 recyclerview
的代码
androidx.cardview.widget.CardView
implementation 'androidx.recyclerview:recyclerview:1.0.0'
而且我已经用
更改了布局文件
<androidx.recyclerview.widget.RecyclerView
.
.
.
</androidx.recyclerview.widget.RecyclerView>
我在尝试同步时遇到标题为上面的错误。
这是我的布局文件
