How to change card_view:cardCornerRadius programmatically

Question

In my project, I am using RecyclerView in my listing using CardView. In my listing I have to set the corner radius of CardView dynamically based on device.

Is there any way to set cardview corner radius value dynamically?

Thanks.

Answer 1

Use CardView.setRadius(float), see androidx.cardview.

(It is worth noting that this will have no effect if you also invoke setBackgroundColor, make sure to use setCardBackgroundColor instead).

You must specify a pixel size, rather than dp value, e.g. for corner radius of 4dp you can invoke, in Kotlin:

radius = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 4f, context.resources.displayMetrics)
