Thanks! I will try this later: if(mymarker.getMap()) mymarker.setMap(null); //turn off the marker if it was shown
But how do you mean with the other part? Could you perhaps show an example how the code will look, using just one polyline and arrays, the part that show the polyline and how to hide it? Thanks in advance! It's so fun to learn more! :) On 29 Juni, 01:02, Chad Killingsworth <[email protected]> wrote: > With most features for the map, you can find out if they are currently > displayed by using the getMap methods.
