HappyKatz solution has a tricky bug. Is there any reason for drawing bitmap when dX==0?? In some cases this causes permanent icon visibility above list item. Also icons become visible above list item when you just touch list item and dX==1. To fix these:

        if (dX > rectOffset) {
            c.drawRect((float) itemView.getLeft(), (float) itemView.getTop(), dX,
                    (float) itemView.getBottom(), leftPaint);
            if (dX > iconOffset) {
                c.drawBitmap(leftBitmap,
                        (float) itemView.getLeft() + padding,
                        (float) itemView.getTop() + ((float) itemView.getBottom() - (float) itemView.getTop() - leftBitmap.getHeight()) / 2,
                        leftPaint);
            }
        } else if (dX < -rectOffset) {
            c.drawRect((float) itemView.getRight() + dX, (float) itemView.getTop(),
                    (float) itemView.getRight(), (float) itemView.getBottom(), rightPaint);
            if (dX < -iconOffset) {
                c.drawBitmap(rightBitmap,
                        (float) itemView.getRight() - padding - rightBitmap.getWidth(),
                        (float) itemView.getTop() + ((float) itemView.getBottom() - (float) itemView.getTop() - rightBitmap.getHeight()) / 2,
                        rightPaint);
            }
        }
