android google maps v2 or v3 to recognize the polygon click event

Question

I am using android google maps v2 now and I have implemented polygon based on the lat/long and i would like to recognize the polygon click event .

But was unable to do so. I would like to know should I use maps v3 as it has onClickListner for polygon-id or is there anything similar for google maps v2 ?

Please let me know.Appreciate any help .Thanks in Advance.

Condition:
I am looking to implement every state with different colours and onClick event for each polygon.
Please suggest the best alternative for the above implementation.

There is no Maps V3 for Android. There may be one with that number for JavaScript maps, which you are welcome to try to use in a `WebView`. AFAIK, a polygon is not clickable in Maps V2. — CommonsWare, Sep 25 '13 at 20:54
Thank you for your time.Is polygon onclick present in v3 android ?? — Jason Wood, Sep 25 '13 at 21:04
That I cannot say, as I do not develop JavaScript maps with Google Maps, let alone try hosting them in a `WebView` -- sorry! — CommonsWare, Sep 25 '13 at 21:08

I have just worked on something similar. As best I can tell, there is no click event for polygons in Google Maps for Android API v2. There are a couple of different solutions available that I won't go into.

The simplest method is to rely on OnMapClickListener. Register the listener and receive onMapClick(LatLng point) callbacks from the GoogleMap. Then use a point in polygon algorithm to determine if the click was inside one of the polygons on the map.

Reference: How can I determine whether a 2D Point is within a Polygon?

Also, to reiterate CommonsWare, there is presently no Maps API v3 for Android. – dm78 Oct 07 '13 at 06:59
