Android disable onScroll() programmatically -

how disable onscroll() programmatically in android?

i have overriden method onscroll() in listactivity. now, need disable method in part of code. need further logic.

without seeng code: set class level variable in activity false when don't want list scroll. check in onscroll() handler , react accordingly.

i have caution against though. user understand why isn't scrolling, or cursing app because has locked up?

if able post code able more (possibly suggest better way).
