Android: How do I resize a ScrollView smaller when the contained TextView is smaller?

Question

I have 2 ScrollView's, each containing a TextView. The second ScrollView is set visibility="gone" normally, and the ScrollView displays full screen.

When a footnote reference in the upper TextView is touched, the specified footnote is loaded and displayed correctly in the second ScrollView and it's made visible. At this point, it's scrollable and works great.

But, when the loaded footnote is smaller then the specified ScrollView area, I would like the ScrollView to shrink in height to only the necessary size to display the content.

Any ideas? Basically, I want the second ScrollView to resize based on it's child TextView's content, up to a set maximum size.

Eventually, I want to allow the user to be able to resize the footnote view by dragging...but that is later.

Do not use weight attribute. Remove layout_weight from both the scroll views.

or

and one more thing if you want to use layout_weight attribute, then set height to 0dip. It will work fine. There is no sense in using both of these attributes together.

Thanks

Hmmm...when I removed the layout_weight from the scroll views, the footnote doesn't display at all. – Darren Ehlers Jul 23 '11 at 18:13
No, the footnote appears to have a height of zero and doesn't show now. – Darren Ehlers Jul 23 '11 at 20:24
