Change Basemap

Demonstrates how to change the ArcGISMap's basemap. A basemap is beneath all other layers on an ArcGISMap and is used to provide visual reference to other layers.

How it works

To change the ArcGISMap's Basemap:

  1. Create an ArcGIS map, ArcGISMap(Basemap, latitude, longitude, scale).
    • Basemap, use basemap type to access a basemap for map, Basemap.Type.NATIONAL_GEOGRAPHIC
    • latitude and longitude coordinate location
    • scale, level of detail displayed on MapView
  2. Set the ArcGIS map to the map view.
  3. Choose a new Basemap.Type and set it to the ArcGIS map to change it.
