create view over cardview in android

Question

I want to create this layout

this is a cardview (gray view) and imageview(blue view) for that i use this code

Answer 1

The CardView has by default elevation in API 21+, you can manipulate the elevation to be less than that of the ImageView

in Pre 21 you can use

overlayView.bringToFront();
root.requestLayout();
root.invalidate();

This will not work in 21+ if you have different elevation
