CardView 导致应用程序崩溃(如图所示)
CardView is causing app to crash (shown in the picture)
每次我 运行 代码时我总是崩溃,我试图删除 CardView 代码并且它不再崩溃了。你们能帮帮我吗,因为我是这个环境的新手,目前正在做一个项目,我是不是用 cardView 代码做错了?谢谢

android:layout_marginEnd
Specifies extra space on the end side of this view. This space is
outside this view's bounds. Margin values should be positive.
您应该在 androidx.cardview.widget.CardView
部分使用正确的值。
不要
android:layout_marginEnd="@+id/soilIv"
应该是
android:layout_marginEnd="10dp"
