Ok, I've done some reading and I have a working theory:
It's done using something this:
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
switch (keyCode)
{
case KeyEvent.KEYCODE_DPAD_DOWN:
(increment static value X by Y );
break;
{
This way a faster swipe results in a higher value?
Sound logical or am I off?
Thanks again,
Josh Beck
