v2.0 ArcGISLayerInfo & Legend

RobertoCodarini

Hi!

I'm trying ArcGISLayerInfo.getLegend() method to build a table of contents, the method retrieveLegendInfo() on the ArcGISDynamicMapServiceLayer object returns always false.

Do you have any suggestion?

Best Regards
Rob

Try to call retrieveLegendInfo() in separate thread after layer is loaded, like this:

mapView.setOnStatusChangedListener(new OnStatusChangedListener() {

                    @Override

                    public void onStatusChanged(Object o, STATUS status) {

                        if (status == STATUS.LAYER_LOADED) {

                            if (o instanceof ArcGISDynamicMapServiceLayer) {

                                //retrieving legend info

                                new AsyncTask<Void, Void, Void>() {

                                    @Override

                                    protected Void doInBackground(Void... voids) {

                                        dynamicLayer.retrieveLegendInfo();

                                        return null;

                                    }

                                }.execute();

                            }

                        }

                    }

                });
