Public Methods
public abstract Marker addMarker (MarkerOptions markerOptions)
Adds a single marker to the map.
Parameters
| markerOptions | the MarkerOptions which defines marker properties such as
position. The options will be copied into the Marker and are safe to re-use. |
|---|
Returns
- an object representing the marker
public abstract Projection getProjection ()
Returns a Projection object that you can use to convert between screen coordinates and
latitude/longitude coordinates.
The Projection returned is a snapshot of the current projection, and will not
automatically update when the camera moves. As this operation is expensive, you should get the
projection only once per screen. Google Maps uses the Mercator projection to create its maps
from geographic data and convert points on the map into geographic coordinates.
Returns
- The
Projectionof the map in its current state ornullif the map has not been fully initialized.
public abstract void removeAllMarkers ()
Removes all the markers currently on the map.
public abstract void removeMarker (Marker marker)
Removes the specified marker from the map.
Parameters
| marker | the marker to remove |
|---|
public abstract void setOnMapClickListener (NavigationMap.OnMapClickListener listener)
Sets a callback that's invoked when the map is tapped.
Parameters
| listener | The callback that's invoked when the map is tapped. To unset the callback, use
null.
|
|---|
public abstract void setOnMarkerClickListener (NavigationMap.OnMarkerClickListener listener)
Sets a callback that's invoked when a marker is clicked.
Parameters
| listener | The callback that's invoked when a marker is clicked. To unset the callback,
use null.
|

public abstract void setPadding (int left, int top, int right, int bottom)
Sets the padding for the UI elements within the map area in px. This also affects the recentering behavior, causing the map to be recentered within the padded area.
Note: The top padding value only applies when the header is disabled (see setHeaderEnabled(boolean)), and the bottom padding only applies when the ETA card is
disabled (see setEtaCardEnabled(boolean)). The left and right padding values
apply at all times.
Parameters
| left | |
|---|---|
| top | |
| right | |
| bottom |
public abstract void setTrafficEnabled (boolean enabled)
Sets whether traffic information will be displayed.
Parameters
| enabled | If true, traffic information will be displayed. |
