Add a point, line, and polygon
Learn how to display point, line, and polygon graphics in a map.
You typically use graphics to display geographic data that is not connected to a database and that is not persisted, like highlighting a route between two locations, displaying a search buffer around a point, or tracking the location of a vehicle in real-time. Graphics are composed of a geometry, symbol, and attributes.
In this tutorial, you display points, lines, and polygons on a map as graphics.
To learn how to display data from data sources, see the Add a feature layer tutorial.
Prerequisites
The following are required for this tutorial:
- An ArcGIS account to access API keys. If you don't have an account, sign up for free.
- Confirm that your system meets the system requirements.
- An IDE for Android development in Kotlin.
Steps
Open an Android Studio project
To start this tutorial, complete the Display a map tutorial. Or download and unzip the Display a map solution in a new folder.
Modify the old project for use in this new tutorial. Expand More info for instructions.
On your file system, delete the .idea folder, if present, at the top level of your project.
In the Android tool window, open app > res > values > strings.xml.
In the
<string name="app_name">
element, change the text content to Add a point, line, and polygon.strings.xmlUse dark colors for code blocks 1 2 3 4 5Change line 1 2 3 4 5
<resources> <string name="app_name">Add a point, line, and polygon</string> </resources>In the Android tool window, open Gradle Scripts > settings.gradle.
Change the value of
rootProject.name
to "Add a point, line, and polygon".settings.gradleUse dark colors for code blocks 1 2 3Change line 1 2 3
include ':app' rootProject.name = "Add a point, line, and polygon"Click File > Sync Project with Gradle files. Android Studio will recognize your changes and create a new .idea folder.
If you downloaded the solution project, set your API key.
An API Key enables access to services, web maps, and web scenes hosted in ArcGIS Online.
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.
In Android Studio: in the Android tool window, open app > java > com.example.app > MainActivity.
In the
setApiKeyForApp()
method, find theArcGISRuntimeEnvironment.setApiKey("YOUR_API_KEY")
call and paste your API key inside the quotes, replacing YOUR_API_KEY.MainActivity.ktUse dark colors for code blocks Change line 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89

Add a graphics overlay
A graphics overlay is a container for graphics. It is used with a map view to display graphics on a map. You can add more than one graphics overlay to a map view. Graphics overlays are displayed on top of all the other layers.
In Android Studio, in the Android tool window, open app > java > com.example.app > MainActivity.
Create a new function named
addGraphics()
.Create a
GraphicsOverlay
to display point, line, and polygon graphics and add it to themapView
's collection of graphics overlays.Call the
addGraphics()
function from theonCreate()

Add a point graphic
A point graphic is created using a point and a marker symbol. A point is defined with x and y coordinates, and a spatial reference. For latitude and longitude coordinates, the spatial reference is WGS84.
Create a
Point
and aSimpleMarkerSymbol
. To create thePoint
, provide longitude (x) and latitude (y) coordinates and aSpatialReference
. Use theSpatialReferences.getWgs84()
convenience function.Point graphics support a number of symbol types such as
SimpleMarkerSymbol
,PictureMarkerSymbol
, andTextSymbol
. Learn more about symbols in the API documentation.Next create a solid, blue, 2px-wide
SimpleLineSymbol
and assign it to theoutline
property ofsimpleMarkerSymbol

Add a line graphic
A line graphic is created using a polyline and a line symbol. A polyline is defined as a sequence of points.
Polylines have one or more distinct parts. Each part is a sequence of points. For a continuous line, you can use the Polyline
constructor to create a polyline with just one part. To create a polyline with more than one part, use a PolylineBuilder
.
Create a
Polyline
and aSimpleLineSymbol
. To create thePolyline
, first create aPointCollection
and add individualPoint
s. Then pass thePointCollection
to thePolyline
constructor.Line graphics support a number of symbol types such as
SimpleMarkerSymbol
andTextSymbol
. Learn more about symbols in the API documentation.MainActivity.ktUse dark colors for code blocks 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 122 122 122 122 122 121 120 119 118 117 116 115 114 113 112 111 110 109 108 107 106 105 104 103 102 101 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100 100Add line.

The Android Emulator should display and run your app in the Android Virtual Devcie (AVD) selected in the Android Studio toolbar:
If your app builds but no AVD displays, you need to add one. Click Tools > AVD Manager > Create Virtual Device...
You should see a point and line graphic along Westward Beach.
Add a polygon graphic
A polygon graphic is created using a polygon and a fill symbol. A polygon is defined as a sequence of points that describe a closed boundary.
Polygons have one or more distinct parts. Each part is a sequence of points describing a closed boundary. For a single area with no holes, you can use the Polygon
constructor to create a polygon with just one part. To create a polygon with more than one part, use a PolygonBuilder
.
Create a
Polygon
and aSimpleFillSymbol
. To create thePolygon
, first create aPointCollection
and add individualPoint
s. Then pass thePointCollection
to thePolygon
constructor.Polygon graphics support a number of symbol types such as
SimpleFillSymbol
,PictureFillSymbol
,SimpleMarkerSymbol
, andTextSymbol
. Learn more about symbols in the API documentation.Next, create a
SimpleFillSymbol
that has a solid, 20%-transparent orange fill, and theblueOutlineSymbol
defined earlier.MainActivity.ktUse dark colors for code blocks 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 144 144 144 144 143 143 143 143 143 143 143 143 143 143 143 143 143 143 143 143 143Add line.

The Android Emulator should display and run your app in the Android Virtual Devcie (AVD) selected in the Android Studio toolbar:
If your app builds but no AVD displays, you need to add one. Click Tools > AVD Manager > Create Virtual Device...
You should see a point, line, and polygon graphic around Mahou Riviera in the Santa Monica Mountains.
