Adding dynamic content to ScrollView causes a dash to the bottom

I implemented my own ScrollView, which detects when a ScrollView position approaches the base and adds views as needed. The problem is that when I add the views to the LinearLayout inside the ScrollView, the scroll down scrolls where I added some views. Is there a way to add views to LinearLayout inside ScrollView that won't cause this behavior?

thank

Edit: this seems to only happen when scrolling. I have a case where I add views to the same ScrollView, but by clicking a button and not scrolling, and I have no problem with a jerk. New views are simply added to the bottom of the LinearLayout scroll.
