HorizonUpdatedListener
interface HorizonUpdatedListener
Interface to horizon update listeners. Used to receive horizon update events during navigation.
To listen to horizon updates while navigating, first implement this interface to create a listener, for example:
val horizonUpdatedListener = object : HorizonUpdatedListener {
override fun onSnapshotUpdated(options: HorizonOptions, snapshot: HorizonSnapshot) {
// add code here that handles the horizon snapshot update
}
override fun onPositionUpdated(options: HorizonOptions, position: HorizonPosition) {
// add code here that handles the horizon position update
}

Then, add the listener you created with the TomTomNavigation object for the set of horizon options for which you wish to receive an update. To do that, use addHorizonUpdatedListener:
tomTomNavigation.addHorizonUpdatedListener(horizonOptions, horizonUpdatedListener)Content copied to clipboard
To stop listening to horizon updates, remove the listener using removeHorizonUpdatedListener:
tomTomNavigation.removeHorizonUpdatedListener(horizonUpdatedListener)Content copied to clipboard
