我正在使用OpenStreetMap。我可以添加此地图并获取当前位置。但是,我无法为自己的位置打分。我使用可绘制文件,但看不到此标记。
这是我的Android来源:
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);
markerosm.xml文件如下:
<?xml version="1.0" encoding="UTF-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#FFFFFFFF" />
<gradient
android:endColor="#DDBBBBBB"
android:startColor="#DD777777"
android:angle="90" />
<corners
android:bottomRightRadius="7dp"
android:bottomLeftRadius="7dp"
android:topLeftRadius="7dp"
android:topRightRadius="7dp" />
</shape>
我没有记错,但看不到。如何解决这个问题?

GeoPoint startPoint = new GeoPoint(20.5992, 72.9342);
Marker startMarker = new Marker(mapView);
startMarker.setPosition(startPoint);
startMarker.setAnchor(Marker.ANCHOR_CENTER, Marker.ANCHOR_BOTTOM);
mapView.getOverlays().add(startMarker);
