Find address

View on GitHub

Sample viewer app

Find the location for an address.

Image of find address

Use case

A user can input a raw address into your app's search bar and zoom to the address location.

How to use the sample

Select an entry from the drop-down menu at the top left of the screen to zoom to the address, marked with a pin.

How it works

Create a LocatorTask using the URL to a locator service.
Set the GeocodeParameters for the locator task and specify the geocode's attributes.
Get the matching results from the GeocodeResult using locatorTask.geocodeAsync(addressString, geocodeParameters).
Create a Graphic with the geocode result's location and store the geocode result's attributes in the graphic's attributes.
Show the graphic in a GraphicsOverlay.

Additional information

This sample uses the World Geocoding Service. For more information, see the Geocoding service help topic on the ArcGIS REST APIs website.
