Java créer un fichier KML avec un marqueur de couleur

Question

Je veux faire un marqueur de couleur dans le fichier kml.

et vérifiez sur google earth.

Maintenant, mes codes sont ceci:

public class GenKMLPlaceMarker { 
public int id; 
public String name; 
public String address; 
public float lat; 
public float lng; 
public String type; 

public static void main(String[] args) { 
    Statement stmt; 
    ResultSet rs; 
    GenKMLPlaceMarker KML = new GenKMLPlaceMarker(); 
    try { 
     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); 
     String url = "jdbc:odbc:디비폼"; 
     Connection con = DriverManager.getConnection(url, "", ""); 
     DocumentBuilderFactory factory = DocumentBuilderFactory 
       .newInstance(); 
     DocumentBuilder builder = factory.newDocumentBuilder(); 
     TransformerFactory tranFactory = TransformerFactory.newInstance(); 
     Transformer aTransformer = tranFactory.newTransformer(); 
     Document doc = builder.newDocument(); 
     Element root = doc.createElement("kml"); 
     root.setAttribute("xmlns", "http://earth.google.com/kml/2.1"); 
     doc.appendChild(root); 
     Element dnode = doc.createElement("Document"); 
     root.appendChild(dnode); 

     //레스토랑 스타일 구성 
     Element rstyle = doc.createElement("Style"); 
     rstyle.setAttribute("id", "restaurantStyle"); 
     Element ristyle = doc.createElement("IconStyle"); 
     ristyle.setAttribute("id", "restaurantIcon"); 
     Element rcolor = doc.createElement("Color");// 아이콘에 색 부여하기???? 
     Element ricon = doc.createElement("Icon"); 
     Element riconhref = doc.createElement("href"); 
     riconhref.appendChild(doc.createTextNode("http://maps.google.com/mapfiles/kml/pal2/icon63.png")); 
     rstyle.appendChild(ristyle); 
     ricon.appendChild(riconhref); 
     ristyle.appendChild(ricon); 
     dnode.appendChild(rstyle); 

     //바 스타일 구성 
     Element bstyle = doc.createElement("Style"); 
     bstyle.setAttribute("id", "barStyle"); 
     Element bistyle = doc.createElement("IconStyle"); 
     bistyle.setAttribute("id", "barIcon"); 
     Element bicon = doc.createElement("Icon"); 
     Element biconhref = doc.createElement("href"); 
     biconhref.appendChild(doc.createTextNode("http://maps.google.com/mapfiles/kml/pal2/icon27.png")); 
     bstyle.appendChild(bistyle); 
     bicon.appendChild(biconhref); 
     bistyle.appendChild(bicon); 
     dnode.appendChild(bstyle); 



     stmt = con.createStatement(); 
     rs = stmt.executeQuery("SELECT * FROM markers"); 
     while (rs.next()) { 
      KML.id = rs.getInt("id"); 
      KML.name = rs.getString("name"); 
      KML.address = rs.getString("address"); 
      KML.lat = rs.getFloat("lat"); 
      KML.lng = rs.getFloat("lng"); 
      KML.type = rs.getString("type"); 
      Element placemark = doc.createElement("Placemark"); 
      dnode.appendChild(placemark); 
      Element name = doc.createElement("name"); 
      name.appendChild(doc.createTextNode(KML.name)); 
      placemark.appendChild(name); 
      Element descrip = doc.createElement("description"); 
      descrip.appendChild(doc.createTextNode(KML.address)); 
      placemark.appendChild(descrip); 
      Element styleUrl = doc.createElement("styleUrl");//스타일 설정하기 위해 선언하는 부분 아이콘으로 나타낸다 
      styleUrl.appendChild(doc.createTextNode("#" + KML.type+ "Style"));//bar restaurant 인지를 읽어와서 스타일 부여하는 부분 
      placemark.appendChild(styleUrl); 
      Element point = doc.createElement("Point"); 
      Element coordinates = doc.createElement("coordinates"); 
      coordinates.appendChild(doc.createTextNode(KML.lng + "," 
        + KML.lat)); 
      point.appendChild(coordinates); 
      placemark.appendChild(point); 
     } 
     Source src = new DOMSource(doc); 
     Result dest = new StreamResult(new File("c:/PlaceMarkers.kml")); 
     aTransformer.transform(src, dest); 
     System.out.println("Completed....."); 
    } catch (Exception e) { 
     System.out.println(e.getMessage()); 
    } 
} 
}

Vous devez ajouter l'élément de couleur à votre IconStyle comme l'exemple qui suit (marqueur rouge). Au moins, c'est ce que google map génère lorsque vous changez la couleur d'une icône et que vous l'enregistrez en tant que kml et je n'ai rien vu de tel dans votre code.

<Style id="stackOverflowExample_dining"> 
    <IconStyle> 
     <color>ff0000ff</color> 
     <scale>1.4</scale> 
     <Icon> 
      <href>http://maps.google.com/mapfiles/kml/shapes/dining.png</href> 
     </Icon> 
     <hotSpot x="0.5" y="0" xunits="fraction" yunits="fraction"/> 
    </IconStyle> 
    <ListStyle> 
    </ListStyle> 
</Style>
