I was wondering how to load an already created kml file into the mapview programatically? The kml file is stored in the SDcard. I have a mapActivity already set up. Do I just SAX parse the kml file and use the draw method to create the boundary? Here is a snippet of the kml file stored on the phone

推荐答案
您可以解析使用类似一个SAXParser的KML文件，并得到了坐标的方式点。
You could parse the KML file using something like a SAXParser and get the coordinates for your way-points.
然后，你可以把它们画在MapActivity：链接
Then, you could draw them on the MapActivity: Link
