How to set zoom level of a Google map according to marker locations

Question

I have placed two markers on a Google map. One is in the USA and other one is somewhere in Asia. Google only gives zoom levels 1, 2, 3, 4, 5, 6, etc.

I don't want to hard-code the zoom level. How can I display all markers depending upon distance? I.e. if two items are very close to each other or in the same city, a close zoom level should be used, and if they're far apart, then maximum zoom level should be used.

Are you talking about Google Maps API on the web or about the MapView class used in Android to display Google maps? — Flo, Dec 01 '10 at 08:56

You need to include those markers into a bounding box, then use the LatLngBounds object below to set the camera on it:

private void addMarkers() {
    MarkerOptions markerOptions = new MarkerOptions();
    LatLngBounds.Builder boundsBuilder = new LatLngBounds.Builder();

    //add the marker locations that you'd like to display on the map
    boundsBuilder.include(new LatLng(lat1, lng1));
    boundsBuilder.include(new LatLng(lat2, lng2));

    final LatLngBounds bounds = boundsBuilder.build();

    CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngBounds(bounds, width, height, padding);
    map.animateCamera(cameraUpdate);
}

You can specify the zoom level on location and with zoom level

mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(37,
            -121), 6));

What are you using to generate your maps? I'm making use of the GMap2 API in a project of mine from about 8 months back, and it looks like I just had to call 'GDirections(map{{div}});' on, well, the map div in order to get it to display a route between two locations, and adjust the level of zoom appropriately.
