                                      MapView mapView)

Overrides:

draw

public void draw(Canvas c,
                 MapView osmv,
                 boolean shadow)

Description copied from class: ItemizedOverlay

Draw a marker on each of our items. populate() must have been called first.

The marker will be drawn twice for each Item in the Overlay--once in the shadow phase, skewed and darkened, then again in the non-shadow phase. The bottom-center of the marker will be aligned with the geographical coordinates of the Item.

The order of drawing may be changed by overriding the getIndexToDraw(int) method. An item may provide an alternate marker via its OverlayItem.getMarker(int) method. If that method returns null, the default marker is used.

The focused item is always drawn last, which puts it visually on top of the other items.

Overrides:

draw in class ItemizedOverlay<Item extends OverlayItem>

Parameters:

c - the Canvas upon which to draw. Note that this may already have a transformation applied, so be sure to leave it the way you found it

osmv - the MapView that requested the draw. Use MapView.getProjection() to convert between on-screen pixels and latitude/longitude pairs

shadow - if true, draw the shadow layer. If false, draw the overlay contents.

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:

onDetach in class ItemizedIconOverlay<Item extends OverlayItem>
