是否可以更改 InfoWindow 的边框颜色、对齐方式、填充和其他属性？我已经找了一个星期了，但我总是在这里。而且它不提供代码。

这是我的代码。

        //Declare an infoWindow variable - shows when a marker is tapped/clicked
        var infoWindow = new google.maps.InfoWindow;

        // Change this depending on the name of your PHP file
        downloadUrl("outputXML.php", function(data)
        {
            var xml = data.responseXML;
            var markers = xml.documentElement.getElementsByTagName("marker");
            for (var i = 0; i < markers.length; i++) {
            var name = markers[i].getAttribute("name");
            var address = markers[i].getAttribute("address");
            var type = markers[i].getAttribute("type");
            var point = new google.maps.LatLng(
                    parseFloat(markers[i].getAttribute("lat")),
                    parseFloat(markers[i].getAttribute("lng")));
            var html = "<b>" + name + "</b> <br/>" + address;
            var icon = customIcons[type] || {};
            var marker = new google.maps.Marker({
                map: map,
                position: point,
                icon: icon.icon,
                title:name
                });
            bindInfoWindow(marker, map, infoWindow, html);
            }
       });               
        
        function bindInfoWindow(marker, map, infoWindow, html) {
            google.maps.event.addListener(marker, 'click', function() {
              infoWindow.setContent(html);
              infoWindow.open(map, marker);
            });
          }

          function downloadUrl(url, callback) {
            var request = window.ActiveXObject ?
                new ActiveXObject('Microsoft.XMLHTTP') :
                new XMLHttpRequest;

            request.onreadystatechange = function() {
              if (request.readyState == 4) {
                request.onreadystatechange = doNothing;
                callback(request, request.status);
              }
            };

            request.open('GET', url, true);
            request.send(null);
          }//END FUNCTION BINDINFOWINDOW
        
            function doNothing() {} //For request.onreadystatechange

顺便说一句，我正在从在线数据库中获取这些值，我们不必介意，它们都工作正常，唯一的问题是如何自定义 infoWindow。

请帮我。谢谢。

ADD：我忘了说我会把它插入到一个android应用程序中。我正在使用网络视图。

您传递给 an 的内容InfoWindow可能是：文本、HTML 或 DOM 元素。默认情况下，InfoWindow它的大小适合您传递的任何内容，因此以您描述的方式控制内容的最佳方法是创建一个div，为 分配一个 CSS 类div，然后您将完全控制您的InfoWindow内容的外观。

此外，如果您想更好地控制窗口结构本身的实际外观，您可能需要考虑使用InfoBubble 实用程序库作为标准InfoWindow.

查看此url的示例代码，

在此代码中，InfoBox 从 Google Maps API 扩展 GOverlay 类，并动态创建 div 并绘制到地图中。
