Enable ScrollView to bounces content

I have a ScrollView (and H开发者_高级运维orizontalScrollView also), with some content on then.

I need to enable these views to bounces the content if the user try to pass beyond the limit of the scrollable content. How I do that?

In API Level 9 there is ScrollView.setOverScrollMode().
