ArcGIS Runtime SDK for Java

Feature Layer Geodatabase

Demonstrates how to consume an Esri Geodatabase by using a FeatureLayer and a GeodatabaseFeatureTable.

How it works

To create a Geodatabase and display it as a FeatureLayer:

  1. Create a geodatabase using the provided local resource, new Geodatabase(geodatabaseResourceUrl).
  2. Wait for geodatabase to load, geodatabase.addDoneLoadingListener(runnable)
  3. Get the GeodatabaseFeatureTable from the geodatabase, geodatabase.getGeodatabaseFeatureTable(tableName)
  4. Create feature layer using the table from above, new FeatureLayer(geodatabaseFeatureTable)
  5. Add feature layer to ArcGISMap, map.getOperationalLayers().add(featureLayer)
