This isn't the case in Amsterdam, bicycles and cars will stop for you you or weave around you (depending on the case) if you're on a crosswalk. What they aren't going to do is stop for you just because you're standing on the side of the road by a crosswalk and you vaguely look like you might possibly maybe intend to cross the street. With the amount of tourists in the city that's only going to result in a deadlock (particularly on a bicycle) where you're waiting for them to go, and they're waiting for you. Just start walking across the crosswalk in a predictable manner and maintain your course and heading. It works.
