How to draw an area (circle/polygon) on a mapview in Android?

Question

How can i draw an area, like a circle or a polygon on the mapview with drag on the screen??, i searched for this question and found solutions only to draw lines between projections, but not this.

Moreover i must be able to get the area details after user done with drawing the area, like:

zoom level, center point lat and lng, radius/area

yeah, exactly that is what i mentioned in my question....the question you posted tells how to draw lines between 2 or more Geo points :( — Archie.bpgc, Jun 28 '12 at 06:47
yeah thats for drawing...but this must be done after the user draws(or drags) his finger on the mapview....so how can i get the structure (what the user has drawn)?? — Archie.bpgc, Jun 28 '12 at 06:55

It sounds like you'll need to Override dispatchTouchEvent(). MapView's don't have onTouchListener(), so by using dispatchTouchEvent() you can intercept touches on the mapView, and then use those touches to draw a circle on the map.

As for the zoom level, use mapView.getZoomLevel() and for center use mapView.getMapCenter(). Good luck!
