android - 启用指南针 OSMDROID

Question

如何在 Open Street Map 中启用罗盘模式？

有什么方法还是需要自己创建定位系统？

Answer 1

这就是我启用指南针的方式:

MapView oMap;
IMapController mapController;
.......

mapController = oMap.getController();
mapController.setZoom(zoom);
mapController.setCenter(new GeoPoint(latitude, longitude));
MyLocationNewOverlay oMapLocationOverlay = new 
MyLocationNewOverlay(getApplicationContext(),oMap);
oMap.getOverlays().add(oMapLocationOverlay);
oMapLocationOverlay.enableFollowLocation();
oMapLocationOverlay.enableMyLocation();   

CompassOverlay compassOverlay = new CompassOverlay(this, oMap);
compassOverlay.enableCompass();
oMap.getOverlays().add(compassOverlay);
