我想重叠卡片视图（将图像的一半放在外面）。ShapeableImageView是卡片视图的子视图。

我尝试添加clipChilder="false"卡片视图以及子约束布局，但没有运气。我也在运行时再次尝试了同样的方法，但没有运气。

在我的情况下，您可以将其添加到 MaterialCardView xml 文件中

android:outlineProvider="none"

好吧，所以在尝试了这么多不同的方法后，终于找到了解决方案。

就我而言，我有一张由卡片视图包裹的图像，卡片视图位于约束布局内。所以在这里我必须android:clipChildren="false"为两个视图设置，ConstraintLayout父母和CardView孩子。请参阅下面的最终代码。
