Removing drawn direction from map about googledirectionlibrary

[blackisthesoul]

Just wanna share what I have done

` 
//put List on declaration
 List<Polyline> polylines = new ArrayList<Polyline>();

@Override
    public void onDirectionSuccess(Direction direction, String rawBody) {
        if (direction.isOK()) {
            for (int i = 0; i < direction.getRouteList().size(); i++) {
                Route route = direction.getRouteList().get(i);
                mMap.addMarker(new MarkerOptions().position(origin));
                mMap.addMarker(new MarkerOptions().position(destination));

                ArrayList<LatLng> directionPositionList = route.getLegList().get(0).getDirectionPoint();
                polylines.add(mMap.addPolyline(DirectionConverter.createPolyline(this, directionPositionList, 5, Color.RED)));

            }

            setCameraWithCoordinationBounds(direction.getRouteList().get(0));
            
            //btnRequestDirection.setVisibility(View.GONE);
        } else {
            //Snackbar.make(btnRequestDirection, direction.getStatus(), Snackbar.LENGTH_SHORT).show();
        }
    }`

And then when I want to remove polylines, I create a button to clear all my polylines

public void Clear(View view){ for(Polyline line : polylines) { line.remove(); } polylines.clear(); }

I hope it helps

When you call googleMap.addPolyline() it returns the instance reference. Assign it to a variable, and then you can use the methods within the Polyline class. With the reference you can call Polyline.remove().

Google Docs: Polyline.remove

private Polyline directionsPath;

directionsPath = googleMap.addPolyline();

directionsPath.remove();

Thank you @starr0stealer wasn't aware that an instance is returned!
