ArcGis ，如何向 featuresLayer 添加点？

问题描述

我打算使用 FeatureLayer 和 java API 在 arcgis 地图上插入点。

使用arcgis rest api，我可以添加一个新点，参见>>>> arcgis rest api ...

但是当我使用 java API 在特征层中添加新点时，该函数永远不会被调用，featureTable.addDoneLoadingListener

谁能告诉我是否可以这样做？

enter code here

public class AddPoints {

private ServiceFeatureTable featureTable;
private final String SERVICE_LAYER_URL = "https://services.../FeatureServer/0";

CountDownLatch latch = new CountDownLatch(1);

public void init() {

    String yourAPIKey = "... yourAPIKey ...";
    ArcGISRuntimeEnvironment.setApiKey(yourAPIKey);

    // create a map with the streets basemap style
    ArcGISMap map = new ArcGISMap(BasemapStyle.ARCGIS_STREETS);

    featureTable = new ServiceFeatureTable(SERVICE_LAYER_URL);

    FeatureLayer featureLayer = new FeatureLayer(featureTable);
    
    map.getoperationalLayers().add(featureLayer);
    
    featureTable.addDoneLoadingListener(() -> addPoints(featureTable));

}

private void addPoints(ServiceFeatureTable featureTable) {
    
    Map<String,Object> attributes = new HashMap<>();

    attributes.put("EntityType","test");
    attributes.put("Name","test");
    attributes.put("Address","test");
    attributes.put("City","test");
    attributes.put("ZIP","xxx");

    double x = -10.318673997173935;
    double y = 39.68805765789006;

    Point pt = new Point(x,y,SpatialReference.create(4326));

    // creates a new feature using default attributes and point
    Feature feature = featureTable.createFeature(attributes,pt);

    // check if feature can be added to feature table
    if (featureTable.canAdd()) {
        // add the new feature to the feature table and to server
        featureTable.addFeatureAsync(feature).addDoneListener(() -> applyEdits(featureTable));
    } else {
        // displayMessage(null,"Cannot add a feature to this feature table");
    }
    // addFeaturePoint(featureTable);
    
    latch.countDown();

}

public void launcheme() {

    try {           
        init();
        
        latch.await();
    } catch (InterruptedException e) {
        e.printstacktrace();
    }

}

//addpoint with the api arcgis rest

const featureServiceLayerUrl ="https://***"

const featuretoAdd = {
  attributes: {
    EntityType: 'test',Name: 'test',Address: 'test',City: 'test',ZIP: '-'
  },geometry: {
    x: -10.339787163524841,y: 40.683707245441305,spatialReference: {
      wkid: 4326
    } 
  }
}; 

arcgisRest.addFeatures({
  url: featureServiceLayerUrl,features: [featuretoAdd],authentication
})
  .then(handleAdded);

function handleAdded(response) {
  console.log(response);
  document.getElementById("result-add").textContent = JSON.stringify(response,null,2);

  if (!response.addResults[0].success) {
    // stop early if adding a new feature was not successful
    return;
  }      
}
