[問題] 使用method問題

[fake01 (code)]

想使用別的Java檔中的method

public void locationServiceInitial()
{
  lms = (LocationManager) getSystemService(LOCATION_SERVICE);
  Criteria criteria = new Criteria();
  bestProvider = lms.getBestProvider(criteria, true);
  Location location = lms.getLastKnownLocation(bestProvider);
  getLocation(location);
}
private void getLocation(Location location)
{
  if(location != null) {
  longitude = location.getLongitude();
  latitude = location.getLatitude();
  }
  else {
        Toast.makeText(this, "無法定位座標", Toast.LENGTH_LONG).show();
  }
}

而我在想要呼叫method 的地方寫

public LatitudeAndLongitude LatitudeAndLongitude;

LatitudeAndLongitude = new LatitudeAndLongitude();
LatitudeAndLongitude.locationServiceInitial();

在實機跑的時候，就會程式崩潰，請問該如何解決?

推 asilzheng:你的LatitudeAndLongitude是class name還是member????
