Selecting an object in SceneView

Hi! How to select an object from a ready-made scene loaded from the portal, as in this example ! ArcGIS Runtime SDK for Android 100.4.1

Hi Alexander,

Is there a particular way you're wanting to select an object that is different from how it's demonstrated in the sample? Is it by tapping on it or as a result of some other query?

Cheers,

Clicking on it! I don't know how to work with: ArcGISSceneLayer sceneLayer = new ArcGISSceneLayer(buildings); The example uses a single layer that is loaded by url. How to do the same but with loaded from the scene portal

Hi Alexander,

You should be able to access any scene layers in your scene with a call .getOperationalLayers() and then getting one or more layers from the LayerList. So something like:

for (Layer layer : scene.getOperationalLayers()) {
  if (layer instanceof ArcGISSceneLayer) {
    // follow the above sample for implementing identify and select on the scene layer 
  }
}

I was able to choose only one layer, how to implement for multiple layers?

for (final Layer Layer: mSceneView.getScene().getOperationalLayers()) {
                            if (Layer instanceof ArcGISSceneLayer) {
                                sceneLayer = ((ArcGISSceneLayer) Layer);
                            }
                        }


mSceneView.setOnTouchListener(new DefaultSceneViewOnTouchListener(mSceneView) {

                    @Override
                    public boolean onSingleTapConfirmed(MotionEvent motionEvent) {

                        // clear any previous selection

                        sceneLayer.clearSelection();

                        android.graphics.Point screenPoint = new android.graphics.Point(Math.round(motionEvent.getX()),
                                Math.round(motionEvent.getY()));

                        // identify clicked feature
                        ListenableFuture<IdentifyLayerResult> identify = mSceneView
                                .identifyLayerAsync(sceneLayer, screenPoint, 10, false, 10);

                        identify.addDoneListener(() -> {
                            try {
                                // get the identified result and check that it is a feature
                                IdentifyLayerResult result = identify.get();
                                List<GeoElement> geoElements = result.getElements();
                                if (!geoElements.isEmpty()) {
                                    Log.d(TAG, "geoelement not empty");
                                    GeoElement geoElement = geoElements.get(0);
                                    if (geoElement instanceof Feature) {
                                        // select the feature

                                        sceneLayer.selectFeature((Feature) geoElement);
                                    }
                                }
                            } catch (InterruptedException | ExecutionException e) {
                                String error = "Error while identifying layer result: " + e.getMessage();
                                Log.e(TAG, error);
                                Toast.makeText(MainActivity.this, error, Toast.LENGTH_LONG).show();
                            }
                        });
                        return true;
                    }

                });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hi!

We've got a very similar method for handling that! identifyLayersAsync(...).

There's a sample of it being implemented here (on a MapView, but the syntax is identical for a SceneView--both inherit a GeoView which implements identify). https://github.com/Esri/arcgis-runtime-samples-android/blob/65533272642bd366e31af709c250063ded30219a/java/identify-layers/src/main/java/com/esri/arcgisruntime/sample/identifylayers/MainActivity.java

You'll want to call getElements() on the identify result to get the geoelements you want to select

Kind regards,

Trevor

Hi!

It became even more unclear How to call selectFeature?
