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.

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)
