android - 如何使用 osmdroid NominatimPOIProvider 获取靠近我的位置的一些 bus_stations

Question

我正在尝试使用 osmdroid NominatimPOIProvider 获取靠近我的位置的一些 Bus_station，但我收到以下 NullException:

java.lang.IllegalArgumentException: south must be in [-85.05112877980658,85.05112877980658] at org.osmdroid.util.BoundingBox.set(BoundingBox.java:69).

我确定坐标没有任何点靠近我的位置

所以这是我实现逻辑的方法

 public  void poinOfInt(View view){

     bus_stop = myLocationNewOverlay.getMyLocation();

       NominatimPOIProvider poiProvider = new NominatimPOIProvider( BuildConfig.APPLICATION_ID);
       ArrayList<POI> pois = poiProvider.getPOICloseTo(bus_stop, "highway", 50, 100);


      FolderOverlay poiMarkers = new FolderOverlay();
      map.getOverlays().add(poiMarkers);

      Drawable poiIcon = getResources().getDrawable(R.drawable.marker_default);
      for (POI poi:pois){
          Marker poiMarker = new Marker(map);
          poiMarker.setTitle(poi.mType);
          poiMarker.setSnippet(poi.mDescription);
          poiMarker.setPosition(poi.mLocation);
          poiMarker.setIcon(poiIcon);
         /* if (poi.mThumbnail != null){
            poiItem.setImage(new BitmapDrawable(poi.mThumbnail));
          }*/
         poiMarkers.add(poiMarker);
      }
    }

我收到以下错误:

Answer 1

poiProvider.getPOICloseTo 方法的最后一个参数应该以度为单位(文档说:“到位置的最大距离，以度为单位。请注意，它用于在周围构建边界框位置，而不是圆圈。”)。您通过了 100，这是相当高的度数，所以您可能假设这些是公里或米。尝试较小的值，例如 0.1、0.2 或类似的值 as in examples .
