private SupportMapFragment mMapFragment;

mMapFragment = ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.mapFragment));
mMap = mMapFragment.getMap();

mMapFragment.getView().setVisibility(View.INVISIBLE);



VisibleRegion vr = mMap.getProjection().getVisibleRegion();
double left = vr.latLngBounds.southwest.longitude;
double top = vr.latLngBounds.northeast.latitude;
double right = vr.latLngBounds.northeast.longitude;
double bottom = vr.latLngBounds.southwest.latitude;

getSupportFragmentManager().beginTransaction().hide(myMapView).commit();
getSupportFragmentManager().beginTransaction().show(myMapView).commit();

mMap.getCameraPosition().target

移动地图到某个坐标
mMap.moveCamera(CameraUpdateFactory.newCameraPosition(mMap.getCameraPosition()));
mMap.moveCamera(CameraUpdateFactory.newLatLng(goPoint));
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(goPoint, zoomLevel));
