        .position(new LatLng(0, 0))
        .title("Hello world"));

움직이게 가능한 마커는 아래와 같이 하면된다.

static final LatLng PERTH = new LatLng(-31.90, 115.86);
Marker melbourne = mMap.addMarker(new MarkerOptions()
                          .position(PERTH)
                          .draggable(true));

Position (Required)

The LatLng value for the marker's position on the map. This is the only required property for a Marker object.

Anchor

The point on the image that will be placed at the LatLng position of the marker. This defaults to the middle of the bottom of the image.

Alpha

Sets the opacity of the marker. Defaults to 1.0.

Title

A string that's displayed in the info window when the user taps the marker.

Snippet

Additional text that's displayed below the title.

Icon

A bitmap that's displayed in place of the default marker image. You can't change the icon once you've created the marker.

Draggable

Set to true if you want to allow the user to move the marker. Defaults to false.

Visible

Set to false to make the marker invisible. Defaults to true.

Flat or Billboard orientation

By default, markers are oriented against the screen, and will not rotate or tilt with the camera. Flat markers are oriented against the surface of the earth, and will rotate and tilt with the camera. Both types of markers do not change size based on zoom. Use GroundOverlays if you desire this effect.

Rotation

The orientation of the marker, specified in degrees clockwise. The default position changes if the marker is flat. The default position for a flat marker is north aligned. When the marker is not flat, the default position is pointing up and the rotation is such that the marker is always facing the camera.
