Passing focus from parent to children in Linear Layout

Question

I have a nested series of linear layouts in my xml code. I want the first child of the parent (also a linear layout) to take focus. It does this if I set focusable to true. I would also like pass the focus onto the children of this layout (in order to invoke their state-lists). However it does not pass any of it's focus onto it's children, even if they are set to focusable. Any ideas how to do this? Thanks

Use the XML attribute 'android:duplicateParentState' set to true on the child view to get it to inherit the drawable state of its parent.
