Actually another observation - the slop value seems a lot better in the ListView class, because it looks like once the slop value is passed, scrolling begins "in place".
With ScrollView, when the slop value is passed, the view jumps to where the user's finger is currently located. So for ScrollView (and WebView) it looks like the view pops, while ListView seems to handle this a little better. Maybe there's a way to override ScrollView to have that same behavior? (without making a copy of the source code) Thanks On Nov 20, 4:28 pm, Mark Wyszomierski <mar...@gmail.com> wrote: > Hey Romain, > > Yeah I think it's good, just in the case where I want to scroll slowly > if I'm reading a large chunk of small text, it gets a little tough > (like the google news page etc).
