我想在我的OSMdroid地图中添加标记。我使用的是OSMdroid 5.5版official tutorial建议使用以下代码:

//your items
ArrayList<OverlayItem> items = new ArrayList<OverlayItem>();
items.add(new OverlayItem("Title", "Description", new GeoPoint(0.0d,0.0d))); // Lat/Lon decimal degrees

//the overlay
ItemizedOverlayWithFocus<OverlayItem> mOverlay = new ItemizedOverlayWithFocus<OverlayItem>(items,
    new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
    @Override
    public boolean onItemSingleTapUp(final int index, final OverlayItem item) {
    //do something
        return true;
    }
    @Override
    public boolean onItemLongPress(final int index, final OverlayItem item) {
        return false;
    }
}, mResourceProxy);  // <----- where to get this object from?
mOverlay.setFocusItemsOnTap(true);

mMapView.getOverlays().add(mOverlay);

但是,我不知道从哪里获取mResourceProxy对象。我发现的有关此主题的所有网站(包括OSMdroid的GitHub页面)都使用了DefaultResourceProxyImpl类,该版本自5.2版以来已弃用。

有谁知道如何添加标记版本&gt; = 5.2?

好的,所以我发现了如何使用它。 ItemizedOverlayWithFocus根本不需要ResourceProxy。因此,您可以使用以下构造函数之一:

public ItemizedOverlayWithFocus(Context pContext, List<Item> aList, OnItemGestureListener<Item> aOnItemTapListener) { ... }

public ItemizedOverlayWithFocus(List<Item> aList, OnItemGestureListener<Item> aOnItemTapListener, Context pContext) { ... }

public ItemizedOverlayWithFocus(List<Item> aList, Drawable pMarker, Drawable pMarkerFocused, int pFocusedBackgroundColor, OnItemGestureListener<Item> aOnItemTapListener, Context pContext) { ... }

这是我从我的问题中调整代码以使其工作的方式:

//your items
ArrayList<OverlayItem> items = new ArrayList<OverlayItem>();
items.add(new OverlayItem("Title", "Description", new GeoPoint(0.0d,0.0d))); // Lat/Lon decimal degrees

//the overlay
ItemizedOverlayWithFocus<OverlayItem> mOverlay = new ItemizedOverlayWithFocus<OverlayItem>(
    this, items,  //  <--------- added Context this as first parameter
    new ItemizedIconOverlay.OnItemGestureListener<OverlayItem>() {
    @Override
    public boolean onItemSingleTapUp(final int index, final OverlayItem item) {
    //do something
        return true;
    }
    @Override
    public boolean onItemLongPress(final int index, final OverlayItem item) {
        return false;
    }
});  // <----- removed the mResourceProxy parameter
mOverlay.setFocusItemsOnTap(true);

mMapView.getOverlays().add(mOverlay);
