This post is a recipe for drawing various things on the Google MapView on Android. It assumes that you have a MapView (or MapFragment) set up per this post
Code below assumes that mGMap is the google map object, obtained from:
MapFragment mf = (MapFragment) (getFragmentManager().findFragmentById(R.id.displayMap)); mGMap = mf.getMap();
Draw Marker
// draw marker
MarkerOptions mp = new MarkerOptions();
mp.position(pos);
mp.title("Test Marker");
mp.draggable(false);
mGMap.addMarker(mp);
Center Camera on Location (and Animate)
// center camera CameraPosition cp = new CameraPosition.Builder() .target(pos) .zoom(15) .tilt(45) .build(); mGMap.animateCamera(CameraUpdateFactory.newCameraPosition(cp));
Draw Line
// draw line
if (prevPos != null) {
mGMap.addPolyline(new PolylineOptions()
.add(prevPos, pos)
.width(5)
.color(Color.BLUE)
);
}
