When i Click on a pinpoint it should open a alertdialog in Android Maps

Issue

I have a Main Activity class which loads the current Location of the user. There is a another class which extends ItemizedOverlay. This class takes care of placing a pinpoint. I have one more class which fetches nearby ATM location.. So i use a for loop for placing pinpoints at all nearby atm location. I want my app to pop up when i tap on a particular pin. Showing vicinity of that place.

for(int i=0; i < placeName.length;i++){
nearbylatitude= (int) (lati[i]*1E6);
nearbylongitude=(int) (longi[i]*1E6);
Log.e("Location", nearbylatitude+"\t \t"+ nearbylongitude);
GeoPoint myLocation_nearby_place= new GeoPoint(nearbylatitude, nearbylongitude);    
OverlayItem overlayPlaces=new             OverlayItem(myLocation_nearby_place,placeName[i],vicinity[i]);
custom_Places=new CustomPinpoint(drawable_places,     MainMapActivity.this);
    custom_Places.addPinPoints(overlayPlaces);
     overlayList.add(custom_Places);

    }

This is the for loop which places pin point at nearby Location. I know that there is a Method onTap() with ItemizedOverlay... But i dnt know when to call that function and how to retreive which pin is tapped.

Need a urgent help..

Solution

Use the following:

public OverlayItem(GeoPoint point, java.lang.String title, java.lang.String snippet) Parameters: point - Position of the item. title - Title text. snippet - Snippet text.

OverlayItem currentOverlay = new OverlayItem(CurrLocGeoPoint(),"Text for bubble","");
