public interface DeviceOrientationEvent
extends Event

A DeviceOrientationEvent object describes an event that provides information about the current orientation of the device as compared to the Earth coordinate frame. See Orientation and motion data explained for details.

Method Summary

Methods

Modifier and Type	Method and Description
double	getAlpha() The current orientation of the device around the Z axis; that is, how far the device is rotated around a line perpendicular to the device.
double	getBeta() The current orientation of the device around the X axis; that is, how far the device is tipped forward or backward.
double	getGamma() The current orientation of the device around the Y axis; that is, how far the device is turned left or right.
void	initDeviceOrientationEvent(String type, boolean bubbles, boolean cancelable, double alpha, double beta, double gamma, boolean absolute)
boolean	isAbsolute() This attribute's value is true if the orientation is provided as a difference between the device coordinate frame and the Earth coordinate frame; if the device can't detect the Earth coordinate frame, this value is false.

Method Detail

isAbsolute

boolean isAbsolute()

This attribute's value is true if the orientation is provided as a difference between the device coordinate frame and the Earth coordinate frame; if the device can't detect the Earth coordinate frame, this value is false. Read only.

getAlpha

double getAlpha()

The current orientation of the device around the Z axis; that is, how far the device is rotated around a line perpendicular to the device. Read only.

getBeta

double getBeta()

The current orientation of the device around the X axis; that is, how far the device is tipped forward or backward. Read only.

getGamma

double getGamma()

The current orientation of the device around the Y axis; that is, how far the device is turned left or right. Read only.

initDeviceOrientationEvent

void initDeviceOrientationEvent(String type,
                              boolean bubbles,
