BitmapDescriptorFactory

public final class BitmapDescriptorFactory extends Object

Used to create a definition of a Bitmap image, used for marker icons and ground overlays.

Prior to using any methods from this class, you must do one of the following to ensure that this class is initialized:

• Wait for a GoogleMap to become available from a MapFragment or MapView that you have added to your application. You can obtain the GoogleMap instance by calling getMapAsync() and waiting for the onMapReady(GoogleMap map) callback.
• Call MapsInitializer.initialize(Context). As long as a GooglePlayServicesNotAvailableException isn't thrown, this class will be correctly initialized.

Public Methods

public static BitmapDescriptor defaultMarker (float hue)

Creates a BitmapDescriptor that refers to a colorization of the default marker image. For convenience, there is a predefined set of hue values. See example HUE_YELLOW.

Parameters

hue	The hue of the marker. Value must be greater or equal to 0 and less than 360.

public static BitmapDescriptor defaultMarker ()

Creates a BitmapDescriptor that refers to the default marker image.

public static BitmapDescriptor fromAsset (String assetName)

Creates a BitmapDescriptor using the name of a Bitmap image in the assets directory.

Parameters

assetName	The name of a Bitmap image in the assets directory.

Returns

• the BitmapDescriptor that was loaded from the asset or null if failed to load.

public static BitmapDescriptor fromBitmap (Bitmap image)

Creates a BitmapDescriptor from a given Bitmap image.

Parameters

image

public static BitmapDescriptor fromFile (String fileName)

Creates a BitmapDescriptor using the name of a Bitmap image file located in the internal storage. In particular, this calls Context.openFileInput(String).

Parameters

fileName	The name of the Bitmap image file.

Returns

• the BitmapDescriptor that was loaded from the asset or null if failed to load.

• Using the Internal Storage

public static BitmapDescriptor fromPath (String absolutePath)

Creates a BitmapDescriptor from the absolute file path of a Bitmap image.

Parameters

absolutePath	The absolute path of the Bitmap image.

Returns

• the BitmapDescriptor that was loaded from the absolute path or null if failed to load.

public static BitmapDescriptor fromPinConfig (PinConfig pinConfig)

Creates a BitmapDescriptor from a given PinConfig.

This API does not apply to the Navigation SDK. It exists for compile time compatibility with com.google.android.gms:play-services-maps only.

Parameters

pinConfig	instance to create a bitmap for

Returns

• a BitmapDescriptor that will be created using the given PinConfig

public static BitmapDescriptor fromResource (int resourceId)

Creates a BitmapDescriptor using the resource ID of a Bitmap image.

Parameters

resourceId	The resource ID of a Bitmap image.

Returns

• the BitmapDescriptor that was loaded from the asset or null if failed to load.
