Java ArcGIS program

Question

Is there any example of how to use the mvc (where interface description is in the fxml file) in ArcGIS using Java?

I want to get suface raster image(my_new_task.tif) on the globe. But my code returns just white screen:

enter image description here

My fxml interface code:

<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.layout.StackPane?>
<?import com.esri.arcgisruntime.mapping.view.SceneView?>
<StackPane fx:controller="sample.Controller" 
xmlns="http://javafx.com/javafx/11.0.2" xmlns:fx="http://javafx.com/fxml">
 <SceneView fx:id="sceneView"/>
</StackPane>

My Controller code:

package sample;
import com.esri.arcgisruntime.layers.Layer;
import com.esri.arcgisruntime.layers.RasterLayer;
import com.esri.arcgisruntime.mapping.ArcGISScene;
import com.esri.arcgisruntime.mapping.Basemap;
import com.esri.arcgisruntime.mapping.BasemapStyle;
import com.esri.arcgisruntime.mapping.Viewpoint;
import com.esri.arcgisruntime.mapping.view.SceneView;
import com.esri.arcgisruntime.raster.Raster;
import java.net.URL;
import java.util.ResourceBundle;
import javafx.fxml.FXML;
import javafx.fxml.Initializable;
import javafx.scene.control.ListView;
public class Controller implements Initializable {
 @FXML
 private SceneView sceneView; 
 private Basemap basemap;
 public Controller() {
 }
 @FXML
 public void initialize(URL url, ResourceBundle resourceBundle) {
 this.basemap = new Basemap();
 this.sceneView = new SceneView();
 ArcGISScene scene = new ArcGISScene(this.basemap);
 this.sceneView.setArcGISScene(scene);
 Raster raster = new 
Raster("C:\\Users\\user\\Desktop\\maps\\tif\\my_new_task.tif");
 RasterLayer rasterLayer = new RasterLayer(raster);
 scene.getOperationalLayers().add(rasterLayer);
 rasterLayer.addDoneLoadingListener(() -> {
 if (rasterLayer.getLoadStatus() == LoadStatus.LOADED) {
 System.out.println("raster added");
 Envelope extent = rasterLayer.getFullExtent();
 Viewpoint viewpoint = new Viewpoint(extent);
 this.sceneView.setViewpoint(viewpoint);
 } else {
 System.out.println("Error");
 }
 });
 }
}

My Main code:

package sample;
import com.esri.arcgisruntime.mapping.ArcGISScene;
import com.esri.arcgisruntime.mapping.Basemap;
import com.esri.arcgisruntime.mapping.view.SceneView;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class Main extends Application {
 @Override
 public void start(Stage Stage) throws Exception{
 FXMLLoader loader = new 
FXMLLoader(getClass().getResource("/sample/sample.fxml"));
 Parent root = loader.load(); 
 
 Scene scene = new Scene(root);
 Stage.setTitle("MapArcgis");
 Stage.setWidth(800);
 Stage.setHeight(700);
 Stage.setScene(scene);
 Stage.show();
 }
 public static void main(String[] args) {
 Application.launch(args);
 }
}

Answer 1

"this.sceneView = new SceneView();" in initialize() method was the cause. After deleting it the problem is solved.
