I have item list with latitude and longitude .I want to show the item list on Google map..
so, how to create overlay list and how to show overlays on Google map ?

I make small static map application, in which i take three pin(marker) and set static longitude and latitude. Actually, i want to display balloon annotation for location information display in mapview. when i touch the marker(pin) then balloon annotation is open and display the information for current location. My code is following:

I have been using a previous question and a Google Tutorial to attempt to add multiple pin images on a Google Map view when the current location of the user changes.
Each pin when tapped displays the Longitude and Latitude of the pin.
However currently my code only displays one pin and does not add another image when the location of the user changes. I am relatively new to Android and can't see why this code wouldn't work?

u need implements class LocationListener for listen our location changes and update on the map.
class LocationsListeners implements LocationListener {
#Override
public void onLocationChanged(Location location) {
setLAT(location.getLatitude());
setLON(location.getLongitude());
setGeoPoint(lat, lon);
mapOverlays.add(geoPoint);
}
#Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
#Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
}
u need method for calc the GeoPoint:
public GeoPoint setGeoPoint(double lat, double lon){
geoPoint = new GeoPoint((int) (lat * 1E6), (int)(lon * 1E6));
return geoPoint;
}
or using Little Fluffy Location - Its library that updates our location and notify u, is broadcast receiver, very simple and fast implementation:

Hello, MapView! tutorial covers showing markers on MapView. In the tutorial markers are added as soon as the activity starts, but you can also add markers at later time, for example, when user touches screen. If you try this approach, you'll likely want to override onTap in your subclass of ItemizedOverlay.
Update:
If you follow the tutorial, you'll have your own subclass of ItemizedOverlay. onTap is one of its methods. Now that I look at the documentation, unfortunately onTap(GeoPoint p, MapView mapView) is not public or protected so you cannot override it.
What you can do, is have another overlay, solely for detecting taps. Instead of subclassing ItemizedOverlay, subclass Overlay.
private class TapOverlay extends Overlay {
public boolean onTap(GeoPoint p, MapView mapView) {
// code that adds item in your ItemizedOverlay
// goes here
return true;
}
}
Please help me out, I am working on a Project Xyz having the mapView with add multiple overlays and remove overlays as per userChoice.
To be more clear it filters the overlays as per user choice,,,,
Suppose showing favorite places, friends of a user...
PostLoginServiceHomeBean is my ArrayList with an ArrayList NearByFavoritePlacesList object
entry.getNearByFavoritePlacesList().get(i).getGpsLatitude()
.trim()
i.e by this i'm getting the multiple lat long form server...
The code runs f9 and add the multiple overlays to my map and shows name and address of repective place on overlay tap.But how could I remove the overlays form my map...
I am enclosing the code:Please find the code below:

Here I am giving one solution what I am getting from your question... You need to add Lat Long into Overlay item which is coming from server and add it to itemized overlay, after that when ever you would like to remove any Itemizedoverlay with specific lat long you can check and remove from map overlay as well.
