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);

      • 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
