我正在使用提供Mapbox导航的送货服务开发一个Android应用程序。除了覆盖onArrival方法之外，其他所有操作都进行得很顺利。用户到达目的地后，我想触发一个事件。
public class MapActivity extends AppCompatActivity implements NavigationMetricListeners, OnMapReadyCallback, LocationEngineListener, PermissionsListener, NavigationMetricListeners.ArrivalListener, MapboxMap.OnMapClickListener {

setContentView(R.layout.activity_map_ativity);
mapView = findViewById(R.id.mapView);
mapView.onCreate(savedInstanceState);
lat = Double.valueOf(getIntent().getStringExtra("latitude"));
lon = Double.valueOf(getIntent().getStringExtra("longitude"));
mapView.getMapAsync(this);
Toast.makeText(getApplicationContext(),String.valueOf(lat),Toast.LENGTH_SHORT).show();
startNav = findViewById(R.id.startNavigation);
startNav.setOnClickListener(new View.OnClickListener() {
@Override

NavigationLauncherOptions options = NavigationLauncherOptions.builder()
.origin(originPosition)
