Android: Total height of ScrollView

Question

Hi all,

I have a custom ScrollView (extended android.widget.ScrollView) which I use in my layout. I want to measure the total height of the contents of this scrollview. getHeight() and getMeasuredHeight() don't give me correct values (too high numbers).

Background information: I want to determine how far the user has scrolled. I use onScrollChanged to get the X value, but I need to know a percentage so I'll need the total scrollbar height.

Thanks a lot! Erik
