val mSensorManager = getSystemService(SENSOR_SERVICE) as SensorManager 
 //重力加速传感器
 val accelerationSensor = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER)
 mSensorEventListener = object : SensorEventListener {
   override fun onSensorChanged(event: SensorEvent) {
         val x = event.values[0]
         val y = event.values[1]
        val z = event.values[2]
   }

    override fun onAccuracyChanged(sensor: Sensor?, accuracy: Int) {
      }
}
