Simple Marker Symbol

Demonstrates how to add a SimpleMarkerSymbol to your ArcGISMap.

How it works

To display a SimpleMarkerSymbol:

  1. Create a ArcGISMap's with Basemap.
  2. Create a GraphicsOverlay and add it to the MapView,MapView.getGraphicsOverlays().add().
  3. Add the map to the view, MapView.setMap().
  4. Create a SimpleMarkerSymbol(SimpleMarkerSymbol.Style, color, size).
    • style, how the symbol will be displayed (circle, square, etc.)
    • color, color that the symbol will be displayed
    • size, size of the symbol
  5. Lately, create a Graphic(Geometry, Symbol) method and add it to the graphics overlay.
