That's simply because you cannot hold your finger still. With a mouse cursor you have a 1px precision, with a finger, it's a lot more. The way to "work around" this is simply to use thresholds when you try to detect motion. For instance in a ScrollView or ListView a scroll happens only if the finger has moved by 16 pixels or more. You can use the same values as the framework by looking at the ViewConfiguration class. -- Romain Guy Android framework engineer [email protected] Note: please don't send private questions to me, as I don't have time to provide private support.
