Modifier and Type	Interface and Description
static interface	DeviceDirectionSource.DirectionListener The interface for listening to changes to the device's angle.

Method Summary

Modifier and Type	Method and Description
boolean	isDirectionAvailable() Returns whether the device direction is available.
void	setDirectionListener(DeviceDirectionSource.DirectionListener listener) Sets the listener to receive notifications when the device's direction changes.
void	setTargetDisplay(Display targetDisplay) Sets the display relative to whose orientation the angle is returned.

Method Detail

setTargetDisplay

void setTargetDisplay(Display targetDisplay)

Sets the display relative to whose orientation the angle is returned. For example, a device in landscape orientation "points" to a different direction than one in portrait mode. A null value indicates the device's "natural" orientation.

isDirectionAvailable

boolean isDirectionAvailable()

Returns whether the device direction is available. This may be false, if, for example, the device lacks the hardware sensors needed to determine direction.

setDirectionListener

void setDirectionListener(DeviceDirectionSource.DirectionListener listener)

Sets the listener to receive notifications when the device's direction changes. Call with the null value to remove a previously set listener.
