Android : location.distanceto가 올바르게 작동하지 않습니까?

Question

나는 그것을 사용하여 거리를 계산하는 문제가 있습니다 Location.distanceTo 방법.

private class MyLocationOverlay1 extends MyLocationOverlay {
    @Override
    public void drawMyLocation(Canvas canvas, MapView mapView, Location lastFix, GeoPoint myLocation, long when) 
        super.drawMyLocation(canvas,mapView,lastFix,myLocation,when);

        Location bLocation = new Location("reverseGeocoded");
        bLocation.setLatitude(FindList.gpslat);           // Value = 3.294391E7
        bLocation.setLongitude(FindList.gpslong);         // Value = -9.6564615E7
        Location aLocation = new Location("reverseGeocoded");
        aLocation.setLatitude(myLocation.getLatitudeE6());   // Value = 3.2946164E7
        aLocation.setLongitude(myLocation.getLongitudeE6()); // Value = -9.6505141E7
        aLocation.set(aLocation);    // Don't think I need this   
        bLocation.set(bLocation);    // Don't think I need this either

        int distance = (int)aLocation.distanceTo(bLocation);  // Value = 12637795 ???
        String str = " (" + String.valueOf(distance) + " meters)";
    }
}

누군가 내 거리 계산이 12,637,795 미터를 보여주는 이유를 내 말을 할 수 있습니까?

Answer 1

선을 수정해야합니다.

aLocation.setLatitude(myLocation.getLatitudeE6() / 1e6);
aLocation.setLongitude(myLocation.getLongitudeE6() / 1e6);

라인을 제거하십시오.

aLocation.set(aLocation);
bLocation.set(bLocation);
