[android-developers] Re: ListView

Prepare to be stunned, I think.

I faced a similar issue with horizontal SeekBar's in a vertical
scrolling list. I went through a number of iterations trying to get
these to play nice.

What finally worked, I think would work here, too:

An onTouchEvent(MotionEvent) method that tracks how much it has moved
horizontally and vertically. Beyond a threshold, it goes into "scroll"
mode, and starts scrolling the parent ScrollView with
ScrollView.scrollBy(int, int).

I tried to manage the flow of events in various ways, to route the
events to the scroller. That turned out to be a lot harder than I
expected. This turned out to be quite easy.

The situation here will be slightly different in that you need to pass
the events down to the children. I think super.onTouchEvent(event)
will handle this for you, but I've found there's a few things about
the event handling that I don't fully understand and can't readily
reverse-engineer from simple observations. I haven't read the code...
