我正在尝试将 Google Maps Android API V2 的工作示例放在一起。我找到了四个描述如何做到这一点的教程（DJ-android，Vogella，来自官方文档的 2 个教程），但没有一个有效。我从许多其他开发人员那里找到了近十篇类似这篇文章的帖子，它们都存在完全相同的问题：“Binary XML file line #x Error inflating class”。在 stackoverflow 上，十几个帖子都没有一个接受的答案。我知道互联网上任何地方都没有此 API 的工作示例。
我的项目的内容粘贴在下面。我想我拥有所有这些不同帖子中推荐的所有内容，但是，像许多其他人一样，我遇到了这个通货膨胀运行时错误。
这个实际项目取自 Vogella 教程，该教程甚至无法编译。我从其他相同问题的帖子中应用了修复程序。
谁能告诉我如何使这项工作？有谁知道任何地方的工作示例？谢谢，加里
