question: private boolean moveToFinalScrollerPosition ( Scroller scroller ) { scroller . forceFinished ( true ) ; int amountToScroll = scroller . getFinalY ( ) - scroller . getCurrY ( ) ; int futureScrollOffset = ( mCurrentScrollOffset + amountToScroll ) % mSelectorElementHeight ; int overshootAdjustment = mInitialScrollOffset - futureScrollOffset ; if ( overshootAdjustment != 0 ) { if ( Math . abs ( overshootAdjustment ) > mSelectorElementHeight / 2 ) { if ( overshootAdjustment > 0 ) { overshootAdjustment -= mSelectorElementHeight ; } else { overshootAdjustment += mSelectorElementHeight ; } } amountToScroll += overshootAdjustment ; scrollBy ( 0 , amountToScroll ) ; return true ; } return false ; }
target:  Move to the final position of a scroller. Ensures to force finish the scroller and if it is not at its final position a scroll of the selector wheel is performed to fast forward to the final position.
