An immutable class that aggregates all camera position parameters such as location, zoom
level, tilt angle, and bearing. UseCameraPosition.Builder
to construct aCameraPosition
instance, which you can then use in conjunction withCameraUpdateFactory.
For more information, seeMoving the
camera.

Inherited Method Summary
Fields
public final float bearing
Direction that the camera is pointing in, in degrees clockwise from north.
public finalLatLng target
The location that the camera is pointing at.
public final float tilt
The angle, in degrees, of the camera angle from the nadir (directly facing the
Earth). See
CameraPosition.Builder.tilt(float)for details of restrictions on the range
of values.
public final float zoom
Zoom level near the center of the screen. See
CameraPosition.Builder.zoom(float)for the definition of the camera's zoom
level.
Public Constructors
publicCameraPosition(LatLngtarget, float zoom, float tilt, float bearing)
Constructs a CameraPosition.
Parameters
| target | The target location to align with the center of the screen. Must not be null. |
|---|---|
| zoom | Zoom level at target. See
CameraPosition.Builder.zoom(float)for details of restrictions. |
| tilt | The camera angle, in degrees, from the nadir (directly down). See
CameraPosition.Builder.tilt(float)for details of restrictions. |
| bearing | Direction that the camera is pointing in, in degrees clockwise from north. This value will be normalized to be within 0 degrees inclusive and 360 degrees exclusive. |
Throws
| NullPointerException | iftargetisnull |
|---|---|
| IllegalArgumentException | iftiltis outside the range of 0 to 90 degrees inclusive. |
Public Methods
public staticCameraPosition.Builder builder(CameraPosition camera)
Creates a builder for a camera position, initialized to a given position.
public staticCameraPosition.Builder builder()
Creates a builder for a camera position.
public staticCameraPosition createFromAttributes(Contextcontext, AttributeSet attrs)
Creates a CameraPosition from theAttributeSet.
Returns
nullif eithercontextorattrsis null.
public booleanequals(Objecto)
public staticCameraPosition fromLatLngZoom(LatLngtarget, float zoom)
Constructs a CameraPosition pointed for a particular target and zoom level. The resultant bearing is North, and the viewing angle is perpendicular to the Earth's surface. i.e., directly facing the Earth's surface, with the top of the screen pointing North.
Parameters
| target | The target location to align with the center of the screen. |
|---|---|
| zoom | Zoom level at target. See
CameraPosition.Builder.zoom(float)for details on the range the value
will be clamped to. The larger the value the more zoomed in the camera is. |
