ArcGIS Runtime SDK for Java

Min Max Scale

Demonstrates how to set the minimum and maximum scale of an ArcGISMap.

How it works

To set the min and max scales on a ArcGISMap:

  1. Create an ArcGIS map.
  2. Set min and max scales of map, ArcGISMap.setMaxScale() and ArcGISMap.setMinScale().
  3. Set the ArcGIS map to theMapView.
