Constructor Detail

RotationSensorDirectionSource

public RotationSensorDirectionSource(Context context,
                                     int samplingPeriodUs)

Creates a new RotationSensorDirectionSource with the given context and sample rate in microseconds (see SensorManager.registerListener(SensorEventListener, Sensor, int) for details).

Method Detail

setTargetDisplay

public void setTargetDisplay(Display targetDisplay)

Description copied from interface: DeviceDirectionSource

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.

Specified by:

setTargetDisplay in interface DeviceDirectionSource

isDirectionAvailable

public boolean isDirectionAvailable()

Description copied from interface: DeviceDirectionSource

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

Specified by:

isDirectionAvailable in interface DeviceDirectionSource

setDirectionListener

public void setDirectionListener(DeviceDirectionSource.DirectionListener listener)

Description copied from interface: DeviceDirectionSource

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

Specified by:

setDirectionListener in interface DeviceDirectionSource
