在Android谷歌地图中绘制kml坐标

我正在创建一个Android应用程序来绘制我们当地的山地自行车路线图。坐标来自KML文件。到目前为止，我已经绘制并创建了11个地质点的路径。然而，我有数百个坐标要绘制。这是我迄今为止所做工作的代码。这是可行的，但非常乏味，我还有数百件事要做。有更好的方法吗？有没有办法让我的overlay类从我的kml文件中读取坐标？任何其他想法或想法都将受到赞赏

难道你不能读入KML文件并循环浏览这些点吗？

对不起，我对应用程序编程不熟悉。你会怎么做？这真的超出了这里的答案。你真的应该买一本关于Java的书来学习它。我同意，你有什么可以参考的资料吗？我建议你去书店浏览一下这些书，找到一本与你产生共鸣的书。你也可以在亚马逊上浏览它们。
