Question

我在我的应用程序中使用GPS。我尝试了很多在地图上显示多个位置，但直到我没有得到任何解决方案。如果有人有解决方案来克服我的这个问题。我曾尝试使用此代码。请帮帮我。

提前完成。

        StringBuffer document = new StringBuffer();

        document.append("<location-document>");

        latVec.addElement("19.097971");
        longVec.addElement("72.864761");
        latVec.addElement("19.066985");
        longVec.addElement("72.848969");
        addressVec.addElement("abc");
        addressVec.addElement("wydj");

        for(int j=0;j<latVec.size();j++)
        {                   
            double latlong = Double.parseDouble(latVec.elementAt(j).toString());
            double lonlong = Double.parseDouble(longVec.elementAt(j).toString());

            int lat = (int)latlong*100000;
            int lon = (int)lonlong*100000;
            String addressString = addressVec.elementAt(j).toString();          


            document.append("<location lon='"+ lon +"' lat='"+ lat +"'label='"+ addressString +"' description='"+ addressString +"' />");

        }

        document.append("</location-document>");

        String st = new String(document);

        Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, new MapsArguments(MapsArguments.ARG_LOCATION_DOCUMENT, st));
