If you set GoogleMap.setEnableMyLocation(true);, you get a butto
You can also use:
mMap.animateCamera( CameraUpdateFactory.zoomTo( 17.0f ) );
To just change the zoom value to any desired value between minimum value=2.0 and maximum value=21.0.
The API warns that not all locations have tiles at values at or near maximum zoom.
See this for more information about zoom methods available in the CameraUpdateFactory.
