我可以解析kml文件以显示Android中的路径或点吗？请你能帮助我吗？

这是kml示例代码,我想在android谷歌地图中显示:

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
<Document>
<name>Paths</name>
<description>Examples of paths. Note that the tessellate tag is by default
  set to 0. If you want to create tessellated lines, they must be authored
  (or edited) directly in KML.</description>
<Style id="yellowLineGreenPoly">

我必须做一个项目,我需要计算从我的位置到目的地的距离,并在textview中显示它.请注意,当我的位置发生变化时,这个距离会更新.是否可以制作这种类型的项目？

[注意:没有实施谷歌地图我必须做它.目的地lon,lat是已知的.只需要找到我的位置并进行计算]

我使用这样的网址:

http://maps.google.com/?saddr=546%206th%20Avenue,%20New%20York,%20NY%2010011%20(Sixth%20Avenue,%20New%20York)&daddr=W%20103rd%20St,%20New %20York,%20NY%20&dirflg = R

但它返回完整的html页面.有谁知道如何以json或xml或任何可解析的格式获取此类信息？

我需要公共交通.
