how to set default zoom level in android google map?

i want to set default zoom level in google map to 11 miles can any one guide me how to achieve this?

any help would be appriciate开发者_如何转开发d.

Something like this:

MaView mapView = (MapView)findViewById(R.id.my_map);
MapController mapController = mapView.getController();
mapController.setZoom(14);    // this isn't 11 miles.

Or maybe you have a MapActivity? In that case, the idea is the same, but you'll get the MapView differently.

newLatLngZoom() is the method to set zooming level. 14f is the zoom level.

   mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(marker, 14F))
