HarmonyOS鸿蒙Next中手机方向传感器回调数值异常

HarmonyOS鸿蒙Next中手机方向传感器回调数值异常

手机为荣耀10, 鸿蒙2.0版本； 华为p30, 鸿蒙2.0版本

使用java开发的Android应用(非鸿蒙应用)

在注册方向传感器，获取回调数值时偶现数值异常

代码在下方

sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);            
Sensor sensor = sensorManager.getDefaultSensor(Sensor.TYPE_ORIENTATION);            
if (sensor != null) {
    orientationSensorListener = new SensorEventListener() {
        @Override
        public void onSensorChanged(SensorEvent event) {
            float[] values = event.values;
            float x = Math.abs(values[0]);
            float y = Math.abs(values[1]);
            float z = Math.abs(values[2]);
            float diffX = 0;
            float diffY = 0;
            float diffZ = 0;
            if (preX == Float.MIN_VALUE) {
                preX = x;
            } else {
                diffX = Math.abs(x - preX);
            }
            if (preY == Float.MIN_VALUE) {
                preY = y;
            } else {
                diffY = Math.abs(y - preY);
            }
            if (preZ == Float.MIN_VALUE) {
                preZ = z;
            } else {
                diffZ = Math.abs(z - preZ);
            }
            Log.e("Sensor", "====================================");
            Log.e("SensorCurrent", x + " " + y + " " + z);
            Log.e("SensorPre", preX + " " + preY + " " + preZ);
            Log.e("SensorDiff",  diffX +" "+ diffY +" "+ diffZ);                                               
            if (!isSensorTriggered && (ad.sensorThresholdValue < diffX || ad.sensorThresholdValue < diffY || ad.sensorThresholdValue < diffZ) ) {
                isSensorTriggered = true;                                                      
            }
            //只能触发一次，
            //unRegisterSensor();
            //onAdClick(ad);
        }
    };
    sensorManager.registerListener(orientationSensorListener, sensor, SensorManager.SENSOR_DELAY_NORMAL);
}

当手机平放在桌面上时，value[1]偶现数值为30多，回调几次后变为正常值零点几。请问这是什么原因导致的？如何解决？
