无法解析方法'registerListenercom.xxx.xxx.MainActivity，android.hardware.SensorManager，int'

如何解决无法解析方法'registerListenercom.xxx.xxx.MainActivity，android.hardware.SensorManager，int'

找不到该问题的好答案。

 @Override
protected void onResume() {
    super.onResume();

  mSensorManager.registerListener(MainActivity.this,mSensorManager,SensorManager.SENSOR_DELAY_GAME);
}

无法解析方法'registerListener（com.xxx.xxx.MainActivity，android.hardware.SensorManager，int）'

我不知道该怎么办

我的应用程序应显示指向指南针等目的地的方向。用户将给出纬度和经度。 或者，也许您对如何使用指南针进行定位有不同的想法
