Class RotationMonitor

  • public class RotationMonitor
extends java.lang.Object
    Rotation monitor can be use watch for device rotation changes. It uses Sensor.TYPE_ROTATION_VECTOR sensor if available to detect device rotation changes. If the sensor is not available then the rotation monitor will attempt use the sensors Sensor.TYPE_ACCELEROMETER, Sensor.TYPE_GYROSCOPE and Sensor.TYPE_MAGNETIC_FIELD to detect the rotation changes.

      • getListener

        @Nullable
public RotationMonitor.Listener getListener()
        Gets reference to the current listener that will be notified when an rotation change is detected.
        Returns:
        reference the rotation listener.

      • setListener

        public void setListener​(@Nullable
                        RotationMonitor.Listener listener)
        Sets reference to the current listener that must be notified when an rotation change is detected.
        Parameters:
        listener - reference the rotation listener.

      • startTracking

        public void startTracking()
        Starts the rotation monitor to start tracking for device rotation changes.

      • stopTracking

        public void stopTracking()
        Stops the rotation monitor.

      • getRotation

        public int getRotation()
        Returns the rotation of the screen from its "natural" rotation. The returned value may be Surface.ROTATION_0 (no rotation), Surface.ROTATION_90, Surface.ROTATION_180, or Surface.ROTATION_270. For example, if a device has a naturally tall screen, and the user has turned it on its side to go into a landscape rotation, the value returned here may be either Surface.ROTATION_90 or Surface.ROTATION_270 depending on the direction it was turned. The angle is the rotation of the drawn graphics on the screen, which is the opposite direction of the physical rotation of the device. For example, if the device is rotated 90 degrees counter-clockwise, to compensate rendering will be rotated by 90 degrees clockwise and thus the returned value here will be Surface.ROTATION_90.
        Returns:
        the current rotation.
