GoogleMap.OnMarkerDragListener

  • GoogleMap.OnMarkerDragListener is a callback interface used to handle marker drag events on Google Maps in Android.

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

  • All listener methods are executed on the Android UI thread, ensuring they can interact with UI elements directly.

  • The Marker object provided to the listener methods allows access to the marker's current position during the drag process.
