标签： android kotlin android-cardview

过去4-5天，我一直陷入这个问题。我是Android中Kotlin编程的新手，所以我对此一无所知。运行我的应用程序时，我在Cardview中遇到此错误，错误是：

您使用的是androidX

更改此

<android.support.v7.widget.CardView
      xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:card_view="http://schemas.android.com/apk/res-auto"
            xmlns:tools="http://schemas.android.com/tools"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

      <!--other codes-->

</android.support.v7.widget.CardView>

对此

<androidx.cardview.widget.CardView
         xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:card_view="http://schemas.android.com/apk/res-auto"
                xmlns:tools="http://schemas.android.com/tools"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

       <!--other codes-->

 </androidx.cardview.widget.CardView>
