ArcGIS Runtime SDK for Java

Display Drawing Status

Demonstrates how to display the current DrawStatus of the MapView.

How it works

To use the MapView's DrawStatus:

  1. Create an ArcGISMap.
  2. Set the map to the view MapView, MapView.setMap().
  3. Add MapView.addDrawStatusChangedListener() block and listen when the MapView.DrawStatus changes.
