OK, First post - go gently with me!
Here's the deal: I want a pretty static layout with a small frame on top (filling the screen horisontally), a button at the bottom of the screen (again filling the screen horisontally) and, occupying whatever remains between these 2, a scrolling view with a bunch of radio buttons.
So, at all times I want the top panel (with some textviews in it) and the bottom panel to be visible at the top and bottom respectively. What's left is given to the scroll view with the radio button group.
I start with a LinearLayout (fillparent both ways) containing 3 linearlayout, one for each screen part.
The top (wrapcontent vertically) contains 2 textviews, the lower (wrapcontent vertically) contains the button, and the middle (fillparent vertically) a scrollview. The scrollview in turn contains a radiogroup with radiobuttons.
However, the middle LinearLayout occupies all vertical space below the top, pushing the layout containing the button off screen.
I've attached a screen shot of how it looks, and how I'd like it to look if it can make my point any clearer.
Of cource I'd like the layout to work in both portrait and landscape mode.
