Nesting ViewFlippers

I want to nest several viewflippers. is this possible?

I have not been successful thus far. My first tier flips as required but when I flip to the开发者_如何学JAVA first nested viewflipper its contents appear blank and I can't "flip" it

my views are

V1
V2
V3 -> H1 , H2, H3

When I flip to V3 vertically, H1 does not appear. Where as H is my Horizontal flipper group.

I figured it out. Dropping in a view node after and using some explicit view dimension allowed the next fliper tiers to be visible.
