Problem with multiple scrollviews in Android?

I am facing a problem with nested scrollviews in Android.

I have a scrollview(vertical) in a screen as parent scrollview. Inside this parent scrollview I added tw more child scrollviews (both are 开发者_运维百科vertical). When I scroll up or down at any place only parent scrollview is working fine but not in the child views.

Can any one help me in this issue?

You should control the "focusable" and "clickable" parametres. If an item A of the list has a controllable subitem B, the item A can't be controlled.
