Member Function Documentation

onBoundsChanged()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onBoundsChanged

(

)

The Map's bounds were changed, for example due to a user-initiated zoom or pan event. Users can check Map#BoundingBox() for the updated bounds.

Implemented in com.google.appinventor.components.runtime.Map.

onDoubleTap()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onDoubleTap	(	double	latitude,
		double	longitude
	)

onDoubleTap is raised when the user double-taps on the Map but no feature is present at the location to handle the double-tap event.

Parameters

latitude	Latitude of the double-tap event
longitude	Longitude of the double-tap event

Implemented in com.google.appinventor.components.runtime.Map.

onFeatureClick()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onFeatureClick

(

MapFeature

feature

)

onFeatureClick is raised when the user single-taps on a MapFeature.

Parameters

feature

The map feature clicked by the user.

Implemented in com.google.appinventor.components.runtime.Map.

onFeatureDrag()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onFeatureDrag

(

MapFeature

feature

)

onFeatureDrag is raised as the user drags the map feature. Handlers for this event should run quickly because they block the UI thread and will make the dragging behavior appear sluggish.

Parameters

feature

The map feature the user is dragging.

Implemented in com.google.appinventor.components.runtime.Map.

onFeatureLongPress()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onFeatureLongPress

(

MapFeature

feature

)

onFeatureLongPress is raised when the user long-presses on a MapFeature without moving their location significantly enough to trigger a dragging gesture.

Parameters

feature

The map feature long-pressed by the user.

Implemented in com.google.appinventor.components.runtime.Map.

onFeatureStartDrag()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onFeatureStartDrag

(

MapFeature

feature

)

onFeatureStartDrag is raised when the user starts dragging a MapFeature.

Parameters

feature

The map feature the user has started dragging.

Implemented in com.google.appinventor.components.runtime.Map.

onFeatureStopDrag()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onFeatureStopDrag

(

MapFeature

feature

)

onFeatureStopDrag is raised when the user completes a dragging motion by releasing their touch from the screen.

Parameters

feature

The map feature the user has released from dragging.

Implemented in com.google.appinventor.components.runtime.Map.

onLongPress()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onLongPress	(	double	latitude,
		double	longitude
	)

onLongPress is raised when the user long-presses on the Map without moving their location significantly enough to trigger a panning gesture.

Parameters

latitude	Latitude of the long-press event
longitude	Longitude of the long-press event

Implemented in com.google.appinventor.components.runtime.Map.

onReady()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onReady

(

MapController

map

)

The Map is ready for user interaction.

Parameters

map	The MapController for the underlying Map implementation.

Implemented in com.google.appinventor.components.runtime.Map.

onSingleTap()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onSingleTap	(	double	latitude,
		double	longitude
	)

onSingleTap is raised when the user taps on the Map but no feature is present at the location to handle the tap event.

Parameters

latitude	Latitude of the tap event
longitude	Longitude of the tap event

Implemented in com.google.appinventor.components.runtime.Map.

onZoom()

void com.google.appinventor.components.runtime.util.MapFactory.MapEventListener.onZoom

(

)

The Map's zoom level has changed, for example due to a user-initiated zoom event. Users can check Map#ZoomLevel() for the updated zoom level.

Implemented in com.google.appinventor.components.runtime.Map.
