我通过在应用程序/build.gradle上添加更新的卡视图和应用程序来解决这个问题。
dependencies {
...
compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:cardview-v7:23.4.0'
compile 'com.android.support:recyclerview-v7:23.4.0'
}然后重建这个项目

这个问题也可能是由于使用androidX试图更改为<androidx.cardview.widget.CardView而引起的，崩溃应该是正常的。一个提示，检查是否在预览中看到布局。
在分级中，它应该像：implementation 'androidx.cardview:cardview:1.0.0'

只需在xml文件中定位您的硬视图布局，例如
<android.support.v7.widget.CardView......</android.support.v7.widget.CardView>并代之以
<androidx.cardview.widget.CardView.......</androidx.cardview.widget.CardView>页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
