google-maps - Google Maps v3：多个 KML 图层的 Z-Index 问题

Question

我有一个带有 4 个单独叠加层的 Google Maps (v3) 地图，这些叠加层由 4 个单独的 KML 文件填充。其中三个 KML 文件仅指示地图上的点，我将其渲染为不同颜色（例如红色、蓝色、黄色）的 Google 制造商。第三个覆盖包含多边形的多个坐标（即建筑轮廓）。

问题是多边形（建筑轮廓）位于其他 3 个叠加层中的标记之上。我希望其他三个叠加层（标记）位于多边形之上。

Answer 1

这个线程是由谷歌搜索返回的，所以会注意到谷歌地图已经为 kml 叠加添加了一个 zIndex 规范，现在应该是“答案”

Answer 2

首先将多边形的 KmlLayer 添加到地图中（您可能需要等待它被渲染以确保它位于底部）。有几个功能请求允许指定 layers 的相对 z-index，但尚未实现。

Answer 3

h这里有一个简单的解决方法：将元素放置在特定于其分层需求的文件夹中，为每个文件夹提供一个 TimeSpan - End，其中需要最明显的层的结尾比其他层具有更大的价值。此示例始终将沙坑和三通定位在孔多边形上方。
