GoogleMap.OnMarkerDragListener

  • GoogleMap.OnMarkerDragListener is a callback interface for handling marker drag events in Android Google Maps.

  • It provides three methods: onMarkerDragStart, onMarkerDrag, and onMarkerDragEnd, which are triggered when a marker drag starts, continues, and ends respectively.

  • These methods receive a Marker object, allowing developers to access and manipulate the marker's properties like position during the drag event.

  • All listener methods are executed on the Android UI thread, ensuring interactions with UI elements are safe.
