How do access data attributes from sceneLayer in ArcGIS Runtime SDK for Android (Version 100.2.0)?

[文华李]

How to achieve the access layer attribute data and highlight, here is my code.

/**

                float y = motionEvent.getY();

                double tolerance = 20.0;
                android.graphics.Point point = new android.graphics.Point(Math.round(x), Math.round(y));
                final ListenableFuture<List<IdentifyLayerResult>> featureResult = mSceneView.identifyLayersAsync(point, tolerance, true);
                featureResult.addDoneListener(new Runnable() {

                                List<GeoElement> lstGeo = feature.getElements();

                                Log.i(REACT_CLASS, "layer:" + feature.getLayerContent().getName());
