OSMDROID:错误:类型不兼容:IGeoPoint 无法转换为 GeoPoint [英] OSMDROID: error: incompatible types: IGeoPoint cannot be converted to GeoPoint

问题描述

我正在构建一个来自各种来源的混合和匹配示例 OSMdroid 应用.

I am building a sample OSMdroid app mixing and matching from various sources.

在使用这个示例代码,

import org.osmdroid.util.GeoPoint;
...
 private void setOverlayLoc(Location overlayloc){
   GeoPoint overlocGeoPoint = new GeoPoint(overlayloc);
  //---
     overlayItemArray.clear();

     OverlayItem newMyLocationItem = new OverlayItem(
       "My Location", "My Location", overlocGeoPoint);
     overlayItemArray.add(newMyLocationItem);
  }
...
   @Override
   public void draw(Canvas canvas, MapView mapview, boolean arg2) {
...
     //overlayItemArray have only ONE element only, so I hard code to get(0)
     GeoPoint in = overlayItemArray.get(0).getPoint();

我开始收到以下错误(参考上面最后一行):

I started receiving the following error (in reference to the last line above):

错误:类型不兼容:IGeoPoint 不能转换为 GeoPoint

error: incompatible types: IGeoPoint cannot be converted to GeoPoint

我使用的是 Android Studio 2.0、osmdroid 4.3、slf4j 1.6.1

I am using Android Studio 2.0, osmdroid 4.3, slf4j 1.6.1

错误消息对我来说意义不大，因为我没有声明或导入所说的 IGeoPoint 类.任何有关如何解决此问题的建议将不胜感激.

The error message makes very little sense to me, since i did not declare or import said IGeoPoint class. Any suggestions as to how to go about this would be greatly appreciated.

推荐答案

OverlayItem.getPoint() 返回一个 IGeoPoint，而 Projection.toPixels() 需要一个 IGeoPoint.所以:

OverlayItem.getPoint() returns a IGeoPoint, and Projection.toPixels() needs a IGeoPoint. So :

IGeoPoint in = overlayItemArray.get(0).getPoint();

mapview.getProjection().toPixels(in, out);

(不要回到旧版本，而是升级到最新版本！)

(and don't go back to an older version, but upgrade to the latest one!)
