Scrolling issues with a ListView inside a ScrollView

Question

Here's the scenario conceptually (excluding linearlayouts)

ScrollView
  Button
  Checkboxes
  Spinner
  ListView (full-size, non-scrolling)
AdMob advert

i.e. a scrolling pane, which has a filtering UI at the top, followed by results, but the advert must always remain visible, and when scrolling down the filter UI must scroll away, leaving maximum space for results.

I'm aware there are issues with a ListView inside a ScrollView, though for me it is working well in many ways (I'm fixing the length of the ListView to stop it collapsing). So the screen scrolls nicely, the ad stays put at the bottom, and it looks good.

But the problem I'm seeing is, inexplicably, when the activity opens, the ScrollView is scrolled down a bit, so the ListView is at the top of the screen. I assume this is a default behaviour, so I set about trying to force the scroll position of the ScrollView to the top, but I've tried various methods, and see no effect:

scrollview.scrollTo(0, 1000/-1000);
scrollview.smoothScrollBy(0, 1000/-1000);
scrollview.fullScroll(View.FOCUS_UP);

Is there any way to force the ScrollView to start with the scroll position at the top?

If not, how can I have an ad that doesn't scroll off the bottom, but a filter UI that always scrolls off the top? Using ListView seems overkill as I don't need scrolling but it does provide many benefits so would be nice to avoid starting from scratch and rendering everything myself.

Answer 1

Why are you using a listview if you're not scrolling? Why can't you just use a linearlayout or something more fit to this situation? You mention a filter, you could very easily roll your own filter especially since apparently you just have a few items in your listview.

Answer 2

Use something other that a ListView, you can dinamically generate linearLayouts to show the data you want. You should never use a listview inside a scrollView, it doesnt work for a simple reason, when you scroll, what should scroll, the listview or the scroll view. A couple of people from google have stated not to do this.
