A fix for Daniel Olshansky's DevByte example "ListView Expanding Cells Animation"- collapsing part, when last item is visible from top

ExpendingListView

			int offset = computeVerticalScrollOffset();
			int range = computeVerticalScrollRange();
			int extent = computeVerticalScrollExtent();
			int leftoverExtent = range - offset - extent;

			// In Case Items does not fill the screen (More accurate, if last
			// Item is reachable from offset 0
			boolean isfillingScreen = getBottom() - height +yDelta< getHeight();

			// added line
			if (!isfillingScreen && leftoverExtent < 0)
				leftoverExtent *= -1;

			boolean isCollapsingBelowBottom = (yTranslateBottom > leftoverExtent);
			boolean isCellCompletelyDisappearing = bottom - yTranslateBottom < 0;
			boolean isExtentBeyondRange = leftoverExtent < 0; // fix
			// added line
			if (!isfillingScreen)
				isCollapsingBelowBottom = (yTranslateTop + yTranslateBottom > range) ? false
						: isCollapsingBelowBottom;

			if (isCollapsingBelowBottom && !isExtentBeyondRange) {
				yTranslateTop = yTranslateBottom - leftoverExtent;
				// added line - problematic- last item jumps
				if (!isfillingScreen)
