{latitude = Location.getLatitude（）; longitude = Location.getLongitude（）;

Question

我试图找到我的位置。 它正在工作，但我的本地化是假的!!

这是班级：

        SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                .findFragmentById(R.id.map);
        mapFragment.getMapAsync(this);
       //  gpsTracker= new GPSTracker(getApplicationContext());
       //mLocation=gpsTracker.getLocation();
       // if(mLocation!=null){
        // latitude= mLocation.getLatitude();
       //  longitude= mLocation.getLongitude();
    }//}

        //for (int i = 0;i <g.length; i++) {
        // la.add(g[i].toString());
        //lo.add(s[i].toString());

        // }
    }
