Public Methods

Method

public MarkerOptions alpha(float alpha)

Sets the opacity of a marker.

Parameters:

Parameter name	Parameter desc
alpha	Opacity. The value ranges from 0 (completely transparent) to 1 (completely opaque).

Return:

Return type	Parameter desc
MarkerOptions	MarkerOptions object with new opacity.

Method

public MarkerOptions anchor(float u, float v)

Sets the anchor point of a marker. Since of the values of U and V are fixed, this method always sets the anchor point to the middle of the marker icon. This method has been deprecated. To set an anchor point, call anchorMarker.

Parameters:

Parameter name	Parameter desc
u	U coordinate of the anchor point of a marker. The value ranges from 0 to 1, expressed in a proportion of the marker image width.
v	V coordinate of the anchor point of a marker. The value ranges from 0 to 1, expressed in a proportion of the marker image height.

Return:

Return type	Parameter desc
MarkerOptions	MarkerOptions object with a new anchor point.

Method

public MarkerOptions anchorMarker(float anchorU, float anchorV)

Sets the anchor point of a marker. The anchor point is used to anchor a marker image to the map. The coordinates (0, 0), (1, 0), (0, 1), and (1, 1) respectively indicate the top-left, top-right, bottom-left, and bottom-right corners of the marker image. The following figure shows a marker's anchor point X whose coordinates are (0.5, 0.3).

Parameters:

Parameter name	Parameter desc
u	U coordinate of the anchor point of a marker. The value ranges from 0 to 1, expressed in a proportion of the marker image width.
v	V coordinate of the anchor point of a marker. The value ranges from 0 to 1, expressed in a proportion of the marker image height.

Return:

Return type	Parameter desc
MarkerOptions	MarkerOptions object with a new anchor point.

Method

public MarkerOptions draggable(boolean draggable)

Specifies whether a marker can be dragged.

Parameters:

Parameter name	Parameter desc
draggable	Indicates whether a marker can be dragged. The options are true (yes) and false (no).

Return:

Return type	Parameter desc
MarkerOptions	MarkerOptions object with a new draggability setting.

Method

public MarkerOptions flat(boolean flat)

Specifies whether to flatly attach a marker to the map. If the marker is flatly attached to the map, it will stay on the map when the camera rotates or tilts. Different from GroundOverlay, the marker will remain the same size when the camera zooms in or out. If the marker faces the camera, it will always be drawn facing the camera and rotates or tilts with the camera.

Parameters:

Parameter name	Parameter desc
flat	Indicates whether to flatly attach a marker to the map. The options are true (flatly attaching to the map) and false (facing the camera). The default value is false.

Return:

Return type	Parameter desc
MarkerOptions	MarkerOptions object with a new flat attribute setting.

Method

public float getAlpha()

Obtains the opacity of a marker.

Parameters:
None.
Return:

Return type	Parameter desc
float	Opacity of a marker. The value ranges from 0 to 1.

Method

Obtains the U coordinate of the anchor point of a marker. The coordinate ranges from 0 to 1, starting from the left edge of the marker image.

Parameters:
None.
Return:

Return type	Parameter desc
float	U coordinate of the anchor point of a marker.

Method

public float getAnchorV()

Obtains the V coordinate of the anchor point of a marker. The coordinate ranges from 0 to 1, starting from the top edge of the marker image.

Parameters:
None.
Return:

Return type	Parameter desc
float	V coordinate of the anchor point of a marker.

Method

public BitmapDescriptor getIcon()

Obtains the icon of a marker.

Parameters:
None.
Return:

Return type	Parameter desc
BitmapDescriptor	BitmapDescriptor object of an icon.

Method

public float getInfoWindowAnchorU()

Obtains the U coordinate of the anchor point of a marker's information window. The coordinate ranges from 0 to 1, starting from the left edge of the information window.

Parameters:
None.
Return:

Return type	Parameter desc
float	U coordinate of the anchor point of an information window.

Method

public float getInfoWindowAnchorV()

Obtains the V coordinate of the anchor point of a marker's information window. The coordinate ranges from 0 to 1, starting from the top edge of the information window.

Parameters:
None.
Return:

Return type	Parameter desc
float	V coordinate of the anchor point of an information window.

Method

public LatLng getPosition()

Obtains the position of a marker.

Parameters:
None.
Return:

Return type	Parameter desc
LatLng	Position of a marker.

Method

public float getRotation()

Obtains the rotation angle of a marker.

Parameters:
None.
Return:

Return type	Parameter desc
float	Rotation angle of a marker.

Method

public String getSnippet()

Obtains the text of a marker.

Parameters:
None.

Sets the icon of a marker. If null is passed, the default marker is used.

Parameters:

Parameter name	Parameter desc
iconDescriptor	Object containing an icon.

Return:
