如何使用 androidx 库而不是 android.support.v7.widget.CardView
how to use androidx library instead of android.support.v7.widget.CardView
我想重新设计我的应用程序,我已经在这附近检查了一些代码,但我没有发现它已更新为 compileSdkVersion 30 并使用 androidX 进行布局,而不是 android.support.v7。我的 SDK 是 30。下面是我在这个网站上找到的代码。

您可以使用新的 cardview 依赖项 androidx.cardview:cardview:1.0.0
。
并且在 xml 中使用 <androidx.cardview.widget.CardView/>
而不是 <android.support.v7.widget.CardView/>
。
