Alp*_*tug 1 maps android openstreetmap osmdroid
我正在研究 OpenStreetMap。我可以添加这张地图并获取当前位置。但是,我不能设定我的位置。我使用可绘制文件,但我看不到这个标记。
这是我的Android源:
map = (MapView) findViewById(R.id.map);
map.setTileSource(TileSourceFactory.MAPNIK);
map.setMultiTouchControls(true);
IMapController mapController = map.getController();
mapController.setZoom(16);
GeoPoint currentLocation = new GeoPoint(lat,lon);
mapController.setCenter(currentLocation);
OverlayItem myLocationOverlayItem = new OverlayItem("Here", "Current Position", currentLocation);
Drawable marker = ContextCompat.getDrawable(getApplication(), R.drawable.markerosm);
myLocationOverlayItem.setMarker(marker);
