Android Scrollview Automatically scrolling up

Question

I have a layout with a scrollview and a relative layout inside of the scrollview. I have toggle buttons radio groups and edittext inside this scrollview. The issue I am having is that when I start scrolling down and selecting the toggle buttons, after selection the screen scrolls up automatically to the top. Why is this happening?
