3 years ago 안녕하세요. PlayMap입니다.
지도 로딩 전에 zoomLevel을 가져와서 발생한 오류로 확인됩니다. onCreate 함수 내에서 zoomLevel을 얻기 위해서는 다음과 같이 참고부탁드립니다.
// 지도 생성시 중심점 좌표 설정 mapView.initMap(37.56640, 126.97851, 17);
// 지도 로딩 후 호출 Listener mapView.onMapInitListener(new PlayMapView.OnMapInitCallback() { @Override public void onMapInitEvent(int zoom, PlayMapPoint playMapPoint) { int a = mapView.getZoomLevel(); } });
// 지도 zoomLevel 변경 시 호출 Listener mapView.onZoomLevelChangeListener(new PlayMapView.OnZoomLevelChangeCallback() { @Override public void onZoomLevelChangeEvent(int zoom) { int b = mapView.getZoomLevel(); } });

맵 onCreate 시점 이후에 zoomLevel을 가져오면 아래와 같이 죽고 있습니다. Button내 listener에서는 잘가져오고 있는데, 바로 onCreate 시점 이후에는 호출 시 죽는 것으로 보입니다.
[소스] mMapView = new PlayMapView(this); mMapView = findViewById(R.id.mapView); mMapView.onCreate(savedInstanceState); int a = mMapView.getZoomLevel();
