Android Google maps API V2 center markers

Is there a way to make a map zoom in as far as possible but keeping all of the markers on screen at the same time. I have six markers in a non uniform shape. I was thinking of just taking their centre and locating the map to that, but I still then do not know how far programmatically I can zoom in the map.

These markers change location every time the map is created. Ideally I would have a script that zooms the map in so all are included in the view.

So you understand. I am creating the markers one at a time from json with the following line in a loop.

mMap.addMarker(new MarkerOptions().position(new LatLng(lat,lng)).title(c.getString("title")));


You should use the CameraUpdate class to do (probably) all programmatic map movements.

To do this, first calculate the bounds of all the markers like so:

LatLngBounds.Builder builder = new LatLngBounds.Builder();
for each (Marker m : markers) {

LatLngBounds bounds =;

Then obtain a movement description object by using the factory: CameraUpdateFactory:

int padding = 0; // offset from edges of the map in pixels
CameraUpdate cu = CameraUpdateFactory.newLatLngBounds(bounds, padding);

Finally move the map:


Or if you want an animation:
