Make ImageView fit width of CardView

Question

I have a CardView with rounded corners, I want to have an ImageView at the top like shown in the example taken from the material design guidelines

Answer 1

If your image size (width) is fixed with your ImageView width, you just only have to do is change your ImageView attribute to :

android:scaleType="fitXY"

That is. No additional image corner rounding, no busy work. Beside it efficient for app's performance.

Note : my suggestion may not appropriate for small image with large size ImageView.
