android - Google map Android API V2 问题

标签 android google-maps

我正在尝试整理一个 Google Maps Android API V2 的工作示例。我找到了四个描述如何执行此操作的教程(DJ-android、Vogella、来自官方文档的 2 个教程)，但没有一个起作用。我发现了近十几篇来自许多其他开发人员的帖子，就像这篇文章一样，都存在完全相同的问题:“二进制 XML 文件行 #x 错误膨胀类”。在 stackoverflow 上，十几个帖子中没有一个有一个被接受的答案。据我所知，互联网上没有任何可用的 API 示例。

我的项目内容粘贴在下面。我认为我拥有所有这些不同帖子推荐的所有内容，但是，像许多其他人一样，我遇到了通货膨胀运行时错误。

这个实际项目取自 Vogella 教程，甚至无法编译。我应用了同一问题的其他帖子中的修复程序。

谁能告诉我如何做到这一点？有谁知道任何地方的工作示例吗？ 谢谢，加里

我的工作区中有 Google Play 服务库项目。 。 。 I copied the library project into my workspace

我的主要布局 XML 文件。 。 .

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"

</RelativeLayout>

MainActivity.java 文件。 。 。 (希望代码粘贴在这个论坛上有效)

最佳答案

I know of no working examples of this API anywhere on the internet.

Here are 13 sample projects演示 Maps V2 各个方面的使用。

而且我相当确定您开始使用的一些示例(如果不是全部)也可以工作。

Can anyone tell me how to make this work?

关于:

你得到这个是因为你的 <meta-data>元素位于错误的位置。它必须是 <application> 的子项元素:
