android scrollview inside scrollview scrolling problem

I have added an AbsoluteLayout on ScrollView. Up to this,开发者_JAVA技巧 it worked fine. After that, I added ScrollView on above mentioned AbsoluteLayout. Now I have

 ScrollView -> AbsoluteLayout -> ScrollView -> AbsoluteLayout 

This structure also works fine. But when I try to scroll inner ScrollView, it scrolls slightly and after that outer scrollview starts scrolling.

How can I restrict scrolling outer ScrollView when I am scrolling inner ScrollView?
