Constructor Detail

PolyOverlayWithIW

protected PolyOverlayWithIW(MapView pMapView,
                            boolean pUsePath,
                            boolean pClosePath)

Method Detail

setVisible

public void setVisible(boolean visible)

isVisible

public boolean isVisible()

getOutlinePaint

public Paint getOutlinePaint()

Returns:

the Paint used for the outline. This allows to set advanced Paint settings.

getFillPaint

protected Paint getFillPaint()

Returns:

the Paint used for the filling. This allows to set advanced Paint settings.

setGeodesic

public void setGeodesic(boolean geodesic)

Sets whether to draw each segment of the line as a geodesic or not. Warning: it takes effect only if set before setting the points in the Polyline.

isGeodesic

public boolean isGeodesic()

setInfoWindow

public void setInfoWindow(InfoWindow infoWindow)

Set the InfoWindow to be used. Default is a BasicInfoWindow, with the layout named "bonuspack_bubble". You can use this method either to use your own layout, or to use your own sub-class of InfoWindow. If you don't want any InfoWindow to open, you can set it to null.

Overrides:

setInfoWindow in class OverlayWithIW

Parameters:

infoWindow - the InfoWindow to be opened when tapping the overlay. This InfoWindow MUST be able to handle an OverlayWithIW (as BasicInfoWindow does). Set it to null to remove an existing InfoWindow.

showInfoWindow

public void showInfoWindow()

Show the infowindow, if any. It will be opened either at the latest location, if any, or to a default location computed by setDefaultInfoWindowLocation method. Note that you can manually set this location with: setInfoWindowLocation

setInfoWindowLocation

public void setInfoWindowLocation(GeoPoint location)

Sets the info window anchor point to a geopoint location

getInfoWindowLocation

public GeoPoint getInfoWindowLocation()

Returns:

the geopoint location where the infowindow should point at. Doesn't matter if the infowindow is currently opened or not.

setMilestoneManagers

public void setMilestoneManagers(List<MilestoneManager> pMilestoneManagers)

getDistance

public double getDistance()

Returns:

aggregate distance (in meters)

setDefaultInfoWindowLocation

protected void setDefaultInfoWindowLocation()

Internal method used to ensure that the infowindow will have a default position in all cases, so that the user can call showInfoWindow even if no tap occured before. Currently, set the position on the center of the polygon bounding box.

draw

public void draw(Canvas pCanvas,
                 Projection pProjection)

Overrides:

draw in class Overlay

onDetach

public void onDetach(MapView mapView)

Description copied from class: Overlay

Override to perform clean up of resources before shutdown. By default does nothing.

Overrides:
