An immutable class that aggregates all camera position parameters such as location, zoom
level, tilt angle, and bearing. Use CameraPosition.Builder
to construct a CameraPosition
instance, which you can then use in conjunction with CameraUpdateFactory
.
For more information, see Moving the
camera.

Inherited Method Summary
Fields
public final float bearing
Direction that the camera is pointing in, in degrees clockwise from north.
public final LatLng 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
public CameraPosition (LatLng target, 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 | if target is null |
---|---|
IllegalArgumentException | if tilt is outside the range of 0 to 90 degrees inclusive. |
Public Methods
public static CameraPosition.Builder builder (CameraPosition camera)
Creates a builder for a camera position, initialized to a given position.
public static CameraPosition.Builder builder ()
Creates a builder for a camera position.
public static CameraPosition createFromAttributes (Context context, AttributeSet attrs)
Creates a CameraPosition from the AttributeSet
.
Returns
null
if eithercontext
orattrs
is null.
public boolean equals (Object o)
public static CameraPosition fromLatLngZoom (LatLng target, 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. |
