当我解析kml时,我将所有内容放入一个类中。我在第二个应用程序中使用了第一个应用程序中的相同类。刚刚扩展了原来的课程。对我来说,从另一个应用程序中100%重用一个类并使用超级操作码非常酷。
反正。基本上是折线选项列表和标记选项列表。
super.get_po是折线选项 super.get_mo是标记选项
然后,当我写kml时,我只是将该类序列化。我的高尔夫应用程序取决于标记和线条的顺序。对于每个洞它是标记,线,标记,我使用与http://maps.google.com相同的样式,其中每个元素都有自己的风格。

要在不使用应用程序的情况下将kml加载到Android上的Google地图中,您可以在某处创建一个小的html文件,其中包含指向kml文件的geo-uri链接,然后在任何Android网络浏览器中点击该链接。
例如:假设你的kml文件位于/sdcard/overlay.kml中,那么你写一个这样的geo-uri链接:
<html>
<head><title>Example KML link page using a geo-uri</title></head>
<body>
<a href="geo:0,0?q=file:///sdcard/overlay.kml">overlay.kml</a>
</body>
</html>
点击该链接将启动地图,然后地图将尝试加载您的kml。
(显然,如果您的kml文件位于Web服务器上,则file://部分可以替换为http:// servername)
请注意,Android版本的地图似乎不会处理与桌面版(或桌面版Google地球版)相同的kml元素版本/范围。
