回答1：

这个是不是聚合有关系吗？不就是修改覆盖物样式吗？

官方例子，你可以照着做啊




    
    
    
        body, html {width: 100%;height: 100%;margin:0;font-family:"微软雅黑";}
        #allmap{width:100%;height:500px;}
        p{margin-left:5px; font-size:14px;}
    
    
    添加自定义覆盖物

图示中为房产覆盖物，鼠标移到覆盖物上，自动显示房屋套数

    // 百度地图API功能
    var mp = new BMap.Map("allmap");
    mp.centerAndZoom(new BMap.Point(116.3964,39.9093), 15);
    mp.enableScrollWheelZoom();
    // 复杂的自定义覆盖物
    function ComplexCustomOverlay(point, text, mouseoverText){
      this._point = point;
      this._text = text;
      this._overText = mouseoverText;
    }
    ComplexCustomOverlay.prototype = new BMap.Overlay();
    ComplexCustomOverlay.prototype.initialize = function(map){
      this._map = map;
      var div = this._div = document.createElement("div");
      div.style.position = "absolute";
      div.style.zIndex = BMap.Overlay.getZIndex(this._point.lat);
      div.style.backgroundColor = "#EE5D5B";
      div.style.border = "1px solid #BC3B3A";
      div.style.color = "white";
      div.style.height = "18px";
      div.style.padding = "2px";
      div.style.lineHeight = "18px";
      div.style.whiteSpace = "nowrap";
      div.style.MozUserSelect = "none";
      div.style.fontSize = "12px"
      var span = this._span = document.createElement("span");
      div.appendChild(span);
      span.appendChild(document.createTextNode(this._text));
      var that = this;

      var arrow = this._arrow = document.createElement("div");
      arrow.style.background = "url(http://map.baidu.com/fwmap/upload/r/map/fwmap/static/house/images/label.png) no-repeat";
      arrow.style.position = "absolute";
      arrow.style.width = "11px";
      arrow.style.height = "10px";
      arrow.style.top = "22px";
      arrow.style.left = "10px";
      arrow.style.overflow = "hidden";
      div.appendChild(arrow);

      div.onmouseover = function(){
        this.style.backgroundColor = "#6BADCA";
        this.style.borderColor = "#0000ff";
        this.getElementsByTagName("span")[0].innerHTML = that._overText;
        arrow.style.backgroundPosition = "0px -20px";
      }

      div.onmouseout = function(){
        this.style.backgroundColor = "#EE5D5B";
        this.style.borderColor = "#BC3B3A";
        this.getElementsByTagName("span")[0].innerHTML = that._text;
        arrow.style.backgroundPosition = "0px 0px";
      }

      mp.getPanes().labelPane.appendChild(div);

      return div;
    }
    ComplexCustomOverlay.prototype.draw = function(){
      var map = this._map;
      var pixel = map.pointToOverlayPixel(this._point);
      this._div.style.left = pixel.x - parseInt(this._arrow.style.left) + "px";
      this._div.style.top  = pixel.y - 30 + "px";
    }
    var txt = "银湖海岸城", mouseoverTxt = txt + " " + parseInt(Math.random() * 1000,10) + "套" ;

    var myCompOverlay = new ComplexCustomOverlay(new BMap.Point(116.407845,39.914101), "银湖海岸城",mouseoverTxt);

    mp.addOverlay(myCompOverlay);
