</ScrollView> 

but still no luck. Any ideas? Thanks.

Answer 1

The key here is

ScrollView can host only one direct child

"direct" being the keyword. So you can have

<ScrollView
    ...>
    <LinearLayout>
       ....
       <!-- you can have as many Views in here as you want -->
    </LinearLayout>
</ScrollView>

So, the LinearLayout in the above example would be your one direct child. And that child can have as many children as you want. Which means you can have all of your other LinearLayouts inside that first one. But you can't have more than one on the same hierarchical level.
