android - Eclipse Android 图形布局编辑器坏了

Question

我在 Mac 上运行 Eclipse Helios，刚刚更新到 ADT 9.0.0。它似乎破坏了布局编辑器。每当我尝试使用布局编辑器打开布局 xml 文件时，都会出现错误。编辑器出现“缺少主题”消息，而生成的主要错误如下。

 Selecting page '0' in AndroidXmlEditor failed

我什至尝试重新安装 Eclipse 和 Android 插件，但无济于事。恐怕在网上也找不到任何东西。其他人有同样的问题或有什么建议吗？

Answer 1

我现在偶然发现了同样的问题。 “配置”部分似乎有一个用于选择平台版本的新下拉列表(在我的情况下没有选择)。选择任何一个(例如“Android 2.2”)会使主题选择器出现，并且布局再次起作用。
