googlemap move markers

[marcick]

from tons of examples of googlemap api, I have grabbed a piece of html code that show a map in a webview with some markers.
Now I want to modify marker appearance and position....
What I still have to understand is: is it possible, once I see the map, to change the position of the markers without reloading the map? Or simply chanche de icon or the text in the baloon?
I would like to reload the map only when the user zoom and pan, or when I have to add a new marker outside of the map bounds.
Any hints?

You can have a look at:
Google Maps in webview.
GPSExample in the User's Guide.
Search in the forum with Google Maps.

Best regards.

Yes klaus,
I have surfed a bit throught many examples and your great job also, but this point is still not clear to me: is it possible to change marker icon, position, baloon, etc without reloading the map?
Which is the key to obtain this? Event listener? need webviewextra? javascript?
Just a hint, then I will study. ...

It's quite some time that I haven't played with this.
I'm not sure if you can modify any value without reloading the map.
The baloon has never worked, at least I didn't get it to work.
For this you need the WebViewExtra libray. You can search the forum there are quite some threads about the WebViewExtra libray.
What works is moving a marker and get the new position into B4A without reloading the map.

Best regards.

I found many example on google map API tutorial and grabbing HTML code from those example now I can show a map with multiple markets, custom pushpin, auto zoom and balloon with custom text.
But as I'm asking here, I don't know how to simply hide or move a marker without reloading the map.
I'll try to study more and understand if webviewextra do this job but to be honest, it seems to me not ....

In your map javascript you need to use the Marker setPosition() method to change it's position.

There is also a Marker setVisible() method that you can use to hide a Marker.

No need to reload the map whatsoever.

Martin, My I ask you a private help?
It will be "appreciated", if you guess what I mean.

Sure no problems!

Can you let me have a copy of the web page files and i'll take a look.

PM me if you want an email address to send them to instead of attaching them to a post.
