how to show a button on top of another element?

I am very new to Kotlin and I want to create a simple activity where details of a person are shown with their picture. I want to move the edit button on top of the imageView so it looks a bit better and is not in line with the other elements. The screenshot is also attached below the XML file

here is my XML file for this layout

<?xml version="1.0" encoding="utf-8"?>
