android - OsmDroid 显示当前 LocationIcon 不工作

Question

我在我的 Android 应用程序中使用 OSMDroid。一切正常，除了我无法显示图标来显示我当前的位置。按照我的代码:

openMapView = (org.osmdroid.views.MapView) v.findViewById(R.id.openmapview);
openMapView.setClickable(true);

openMapView.setMultiTouchControls(true);
final float scale = getResources().getDisplayMetrics().density;
final int newScale = (int) (256 * scale);
String[] OSMSource = new String[2];
OSMSource[0] = "http://a.tile.openstreetmap.org/";
OSMSource[1] = "http://b.tile.openstreetmap.org/";
XYTileSource MapSource = new XYTileSource(
    "OSM",
    null,
    1,
    18,
    newScale,
    ".png",
    OSMSource
);
openMapView.setTileSource(MapSource);
mapController = (MapController) openMapView.getController();
mapController.setZoom(14);

// My Location Overlay
myLocationoverlay = new MyLocationOverlay(getActivity(), openMapView);
myLocationoverlay.enableMyLocation(); // not on by default
myLocationoverlay.enableCompass();
myLocationoverlay.disableFollowLocation();
myLocationoverlay.setDrawAccuracyEnabled(true);

myLocationoverlay.runOnFirstFix(new Runnable() {
    public void run() {
        mapController.animateTo(myLocationoverlay.getMyLocation());
    }
});

任何人都可以告诉我我要去哪里以及我应该在我的代码中更改什么。

要启用 MyLocationOverlay，您需要调用:

myLocationoverlay.enableMyLocation();
mMapView.getOverlays().add(mMyLocationNewOverlay);

另外从您的代码中删除这一行:

myLocationoverlay.disableFollowLocation();
