Add Graphics with Symbols

The Add Graphics with Symbols sample demonstrates how to add points, polylines, and polygons as graphics, set a symbol renderer to the graphics and add to a GraphicsOverlay. The sample also adds TextSymbol to represent text as symbols on the GraphicsOverlay.

Developer Pattern

Graphics are added to a GraphicsOverlay without any symbols or styles. To include a symbol with a graphic, create a Graphic with a Symbol and Geometry and add it to the GraphicsOverlay.

//define a polyline for the boat trip
Polyline boatRoute = getBoatTripGeometry();
//define a line symbol
SimpleLineSymbol lineSymbol = new SimpleLineSymbol(SimpleLineSymbol.Style.DASH, Color.rgb(128, 0, 128), 4);
//create the graphic
Graphic boatTripGraphic = new Graphic(boatRoute, lineSymbol);
//add to the graphic overlay
graphicOverlay.getGraphics().add(boatTripGraphic);
