我找到了一个如何在openstreet地图中映射气球的解决方案我根据自己的需要定制osmbonuspack工作正常，但只显示一张地图。
如何在此代码中添加多个标记，我在下面粘贴？
我的输出网址工作正常，请告诉我如何在图片气泡中添加文字以及如何在地图中添加多个标记？

答案 0 :(得分：5)
像这样使用Itemized Overlay（填充方法是最重要的）
public class CustomOverLay extends ItemizedOverlay<OverlayItem> {
private ArrayList<OverlayItem> overlayItems = new ArrayList<OverlayItem>();
private MapView mapView;
public CustomOverLay(Drawable drawable, MapView mapView) {
super(boundCenterBottom(drawable));
this.mapView = mapView;
}
public void addOverlayItem(OverlayItem item) {
overlayItems.add(item);
populate();
}
@Override
protected OverlayItem createItem(int index) {
return overlayItems.get(index);
}
@Override
public int size() {
return overlayItems.size();
}
@Override
protected boolean onTap(int index) {
return true;
}
}
一旦你这样做，请按照下面的代码，为你想要放在地图中的数字标记添加OverlayItem
List<Overlays> mapOverlays = mapView.getOverlays();
CustomOverLay overlays = new CustomOverLay(drawable, mapView);
GeoPoint p = new GeoPoint(getLat(util.getLatitude()), getLong(util.getLongitude()));
OverlayItem overlayItem = new OverlayItem(p, "", "");
overlays.addOverlayItem(overlayItem);
GeoPoint p = new GeoPoint(getLat(util.getLatitude()), getLong(util.getLongitude()));
OverlayItem overlayItem = new OverlayItem(p, "", "");
overlays.addOverlayItem(overlayItem);
..... so on
mapOverlays.add(overlays);
