请问SENSOR_TYPE_DEVICE_ORIENTATION设备方向传感器如何使用？

categoryOrientationAgent = new CategoryOrientationAgent();
CategoryOrientation categoryOrientation = categoryOrientationAgent.getSingleSensor(
    CategoryOrientation.SENSOR_TYPE_DEVICE_ORIENTATION);
categoryOrientationDataCallback = new ICategoryOrientationDataCallback() {
    @Override
    public void onSensorDataModified(CategoryOrientationData categoryOrientationData) {
        degree = categoryOrientationData.getValues()[0];
        handler.sendEvent(0);
    }

    @Override
    public void onAccuracyDataModified(CategoryOrientation categoryOrientation, int i) {
        // Called when sensor accuracy data changes.
        // This method is called by the application layer to process the accuracy data of the sensors.
        HiLog.info(LABEL_LOG, "%{public}s", "onAccuracyDataModified");
    }

    @Override
    public void onCommandCompleted(CategoryOrientation categoryOrientation) {
        // Called when the sensor completes command execution.
        // This method is called by the application layer to process the command execution result of the sensor.
        HiLog.info(LABEL_LOG, "%{public}s", "onCommandCompleted");
    }
};
categoryOrientationAgent.setSensorDataCallback(categoryOrientationDataCallback, categoryOrientation,
    SAMPLING_INTERVAL_NANOSECONDS);

通过修改官方的compass demo，把传感器类型改成设备方向传感器，但是没有回调，请问这个传感器要如何使用？希望有官方人员解答一下！
