there are many ways to detect this. i know you can place a map overlay which runs an onTouchEvent to get the x and y scroll but it will only give you the distance you moved in x and y values in about .1 seconds and then it will rerun and give you another set of x and y distance moves. You can get the the two geopoints, convert them to on screen locations and subtract the two x and y values but you have to tell it when you want it to record the geopoints. Or you can run an onTouchEvent on the mapview but i have never had any luck getting it to run (because the mapview is already running an onTouchEvent) so i wouldnt bother trying.
if you are trying to get the distance moved then using the onTouchEvent on a map overlay is probably your best option but you have to find a way to add all the move distances together as well as find a way to tell it to keep adding the distances together is lift your finger off the screen but if your only trying to detect when a scroll happens then just set an if statement to start what you want to happen on the scroll when either x or y changes. feel free to contact me if you dont get any of this.
