ArcGIS Runtime SDK for Java

Find Place

Demonstrates how find places of interest (POIs) by geocoding near a location or within an specific area.

How it works

To find locations matching a query and a search area:

  1. Create an ArcGISMap's with Basemap.
    • basemap is created using a TileCache to represent an offline resource.
  2. Add the map to the MapView, MapView.setMap().
  3. Create a LocatorTask using a URL and set the GeocodeParameters.
  4. To reverse geocode near a location, pass the location's position into GeocodeParameters.setSearchArea(Geometry) to set the search area.
  5. Limit results to the view's visible area using the MapView.getVisibleArea() method.
  6. Show the matching retrieved results from the LocatorTask.geocodeAsync(String, GeocodeParameters) via PictureMarkerSymbols with a Graphic in a GraphicsOverlay.
