MultiList icon_URLImage

Question

希望你做得很好，我在下面的代码中尝试了icon_URLImage来优化多列表的加载

   while (c.next()) 
   {
         hlist = new Hashtable();
         r = c.getRow();
         hlist.put("Line1", r.getString(6));
         hlist.put("Line2", r.getString(8));
         sb.delete(0, sb.length());
         sb.append("alb").append(r.getInteger(4));
         urlcover = r.getString(10); 
         hlist.put("icon", defaultimg);
         hlist.put("iconName", sb.toString());
         hlist.put("icon_URLImage", urlcover);
         vlist.add(hlist);
    } 
    mlist.setModel(new Model(vlist));
   mlist.setRenderer(createListRenderer());

 In createListRenderer my code is :
 private static MultiButton createRendererMultiButton() {
    MultiButton b = new MultiButton();
    b.setName("icon");
    b.setNameLine1("Line1");
    b.setNameLine2("Line2");
    b.setUIID("Label");
    return b;
}

private static ListCellRenderer createListRenderer() {
    MultiButton sel = createRendererMultiButton();
    MultiButton unsel = createRendererMultiButton();
    return new GenericListCellRenderer(sel, unsel);
}

PlaceHolder已加载，但仍未显示在线图像，请帮助我。对不起，我的英语不太好。

您应该删除该行：

hlist.put("icon", defaultimg);

您在那里放置了一个图像，而URLImage代码认为下载已经完成。

仅供参考这不是MultiList这是MultiButton的列表
