Interface IAOrientationListener

public interface IAOrientationListener

Used for receiving headings and orientation updates from IALocationManager.

Sample usage:

      mOrientationListener = new IAOrientationListener() {
          public void onHeadingChanged(long timestamp, float heading) {
              // handle heading change
          }
          public void onOrientationChange(long timestamp, double [] quaternion) {
              // handle orientation
          }
      }

      // specify sensitivity
      IAOrientationRequest request = new IAOrientationRequest(10.0f, 10.0f);
      mLocationManager.requestOrientationUpdates(request, mOrientationListener);

     

Method Summary

Modifier and Type	Method and Description
void	onHeadingChanged(long timestamp, double heading) Called when the the heading of the device has changed.
void	onOrientationChange(long timestamp, double[] quaternion) Called when the orientation of the device has changed.

Method Detail

onHeadingChanged

void onHeadingChanged(long timestamp,
                      double heading)

Called when the the heading of the device has changed. The heading is the direction of the y-axis projected to the horizontal plane. The values are the same as in IALocation.getBearing() with 0 indicating north, 90 east, and so on. The provided timestamp is consistent with IALocation.getTime()

Parameters:

timestamp - Timestamp

heading - Heading in degrees

onOrientationChange

void onOrientationChange(long timestamp,
                         double[] quaternion)

Called when the orientation of the device has changed. The orientation is given as an unit quaternion with format [w, x, y, z]. The provided timestamp is consistent with IALocation.getTime().

Parameters:

timestamp - Timestamp

quaternion - Quaternion indicating orientation
