我想使用內部函數內部的類成員我嘗試將變量設置為全局變量，但出現錯誤“預期的類或接口”@Override    public void onMapReady(GoogleMap googleMap) {        // Add a marker in current location,        // and move the map's camera to the same location.        //Location currentLocation = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);        FusedLocationProviderClient fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this);        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {            ActivityCompat.requestPermissions(this,                    new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION},                    MY_PERMISSIONS_REQUEST_ACCESS_LOCATION);        }else {            mFusedLocationClient.getLastLocation().addOnSuccessListener(new OnSuccessListener<Location>() {                @Override                public void onSuccess(Location location) {                    wayLongitude = location.getLongitude();                    wayLatitude = location.getLatitude();                    /*LatLng sydney = new LatLng(wayLatitude, wayLongitude);                    googleMap.addMarker(new MarkerOptions().position(sydney)                            .title("Marker in Sydney"));                    googleMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));*/                }            });        }我希望能夠在“OnSuccess”函數中執行“googleMap.addMarker”。我該怎么做？
