Search for an address

Learn how to find an address or place with a search bar and the Geocoding service.

Geocoding is the process of converting address or place text into a location. The Geocoding service can search for an address or a place and perform reverse geocoding.

In this tutorial, you use a search bar in the user interface to access the Geocoding service and search for addresses and places.

To learn how to use the Geocoding service to reverse geocode, visit the Reverse geocode tutorial.

Prerequisites

Steps

Open an Android Studio project

1. To start this tutorial, complete the Display a map tutorial, or download and unzip the solution in a new folder.

2. Modify the old project for use in this new tutorial. Expand More info for instructions.

   More info

   1. On your file system, delete the .idea folder, if present, at the top level of your project.

   2. In the Android tool window, open app > res > values > strings.xml.

      In the <string name="app_name"> element, change the text content to Search for an address.

      strings.xml

      Change line

      1 2 2 3

      1
      2
      3
      4
      <resources>
          <string name="app_name">Search for an address</string>
          <string name="search_hint">Search for an address</string>
      </resources>

   3. In the Android tool window, open Gradle Scripts > settings.gradle.

      Change the value of rootProject.name to "Search for an address".

      settings.gradle

      Change line

      1 2

      1
      2
      include ':app'
      rootProject.name = "Search for an address"

   4. Click File > Sync Project with Gradle files. Android Studio will recognize your changes and create a new .idea folder.

3. If you downloaded the solution project, set your API key.

   More info

   An API Key enables access to services, web maps, and web scenes hosted in ArcGIS Online.

   1. Go to your developer dashboard to get your API key. For these tutorials, use your default API key. It is scoped to include all of the services demonstrated in the tutorials.

   2. In Android Studio: in the Android tool window, open app > java > com.example.app > MainActivity.

   3. In the setupMap function, set the apiKey property on the ArcGISRuntimeEnvironment with your API key.

      MainActivity.kt

Declare graphics overlay and locator task and initialize map view

A graphics overlay is a container for graphics. A locator task converts an address to a point. You will create the properties graphicsOverlay and locatorTask for use later in later steps. Next you will initialize the mapView.

1. In the MainActivitymethod, create a lazy property named graphicsOverlay that references a new GraphicsOverlay for storing geocode result graphics (address location and label).

   More info

   Since graphicsOverlay is a lazy property, a GraphicsOverlay will not be created until the property is initialized, which occurs in the setupMap() method that you will modify shortly.

3. At the end of the setupMap method, initialize the mapView by calling the scope function apply and passing a lambda expression that does the following:

   • assigns the local variable arcGISmap to the map property
   • creates a Viewpoint and pass it to setViewpoint()
   • adds graphicsOverlay to the graphicsOverlays collection.
   More info

   Declared at the start of the MainActivity class, the lazy property graphicsOverlay is initialized at its first access, which is in this lambda expression. The new GraphicsOverlay is not created until now.

Add a UI for user input

To search an address using the application, add a UI element to prompt the user for text input.

The text input will be used as the geocode search text in a later step.

1. In activity_main.xml, add a SearchView element. This widget will display a search text field at the top of the app window.

2. In MainActivity.kt, create a setupSearchViewListener() method to handle user activity by changing the current address in the search field and submitting the search. In the first line, get the bound searchView by calling activityMainBinding.searchView. Then call setOnQueryTextListener() and pass an anonymous class that implements the SearchView.OnQueryTextListener interface.

Create a function to geocode an address

Geocoding is implemented with a locator, typically created by referencing a service such as the Geocoding service or, for offline geocoding, by referencing locator data contained in a mobile package. Geocoding parameters can be used to refine the results, such as setting a maximum number of results or requesting additional attributes in the results.

1. Create a method named performGeocode().

2. Create a new GeocodeParameters method and initialize it by calling the scope function apply and passing a lambda expression that does the following:

   • Adds the names of result attributes to the resultAttributeNames collection. These are the names of attributes to be returned. An asterisk (*) indicates all attributes.
   • Sets maxResults to the maximum number of results to be returned.

     Results are ordered by score, so that the first result has the best match score (ranging from 0 for no match to 100 for the best match).

   • Sets outputSpatialReference to the spatial reference for result locations.

     By default, the output spatial reference is defined by the geocode service. For optimal performance when displaying the geocode result, you can ensure that returned coordinates match those of the map view by providing the map view's spatial reference.

   More info

   When geocoding an address, you can optionally provide GeocodeParameters to control certain aspects of the geocoding operation and specify the kinds of results to return from the locator task. Learn more about these parameters in the API documentation. For a list of attributes returned with geocode results, see Geocoding service output in the REST API documentation.

3. To find the location for the provided address, call geocodeAsync() on the locatorTask, passing the query (the address to find) and the geocodeParameters. The call returns a ListenableFuture, which you should store in the read-only variable geocodeResultFuture.

4. Call addDoneListener on geocodeResultFuture and specify a lambda expression to be executed when geocoding is complete. In the lambda, call displayResult(geocodeResult[0]) to display the first item in the geocodeResult list. This is the location of the address on the map.

   In this tutorial, the maximum results parameter was set to 1, so you pass the first and only item in the geocodeResult list.
