Question

请指导我在这里做什么错误？ 任何帮助，将不胜感激。

private void LoopThroughEachATMToDisplayOnMap() 
      { 


       Drawable drawable = null; 

       for (int i = 0; i < atm.getAtmList().size(); i++) { 

        if(breakFlag) 
         break; 

        drawable = getAppropriatePin(i); 
        if(drawable == null) 
        drawable = getResources().getDrawable(R.drawable.marker); 
        itemizedOverlay = new MyItemizedOverlay(drawable, mapView); 

        ATM a = atm.getAtmList().get(i); 
        if (a != null) { 
         int[] coordinates = getIntCoordinates(a 
           .getCoordinates()); 
         if (coordinates != null) { 
          GeoPoint point = new GeoPoint(coordinates[0], 
            coordinates[1]); 
          OverlayItem overlayItem = new OverlayItem(
            point, a.getBankName(), a.getAddress() 
              + "@@" + a.getPhone() + "@@" 
              + a.getWebAddress() + "@@" 
              + a.getCoordinates()); 
          itemizedOverlay.addOverlay(overlayItem); 
          System.out 
            .println("coordinates-------------------------" 
              + i + " " 
              + coordinates[0] 
              + "," 
              + coordinates[1]); 
         } 

        } 
        if(mapOverlays == null) 
         mapOverlays = mapView.getOverlays(); 

        mapOverlays.add(itemizedOverlay); 
       } 
       System.out.println("atms maps injection complete--------------------------------"); 

      }

Answer 1

我得到了答案我的自我。

实际上mapOverlays.add（itemizedOverlay）;需要用户界面运行。

所以它不是UI线程多数民众赞成为什么它会引发错误。

我刚刚在uithread中运行了该函数，并解决了我的问题。
