如何在 Google Maps API v2 上执行此操作?
MapView mv = (MapView) findViewById(R.id.mvGoogle);
mv.setBuiltInZoomControls(true);
MapController mc = mv.getController();
ArrayList all_geo_points = getDirections(17.3849, 78.4866, 28.63491, 77.22461);
GeoPoint moveTo = all_geo_points.get(0);
mc.animateTo(moveTo);
mc.setZoom(12);
mv.getOverlays().add(new MyOverlay(all_geo_points));
