Eclipse Android图形布局编辑器损坏

我在Mac上运行Eclipse Helios，并且刚刚更新为ADT 9.0.0。它似乎打破了布局编辑器。任何时候我尝试用布局编辑器打开一个布局xml文件时，我得到一个错误。编辑器有一个“丢失的主题”消息，同时产生的主要错误如下。Eclipse Android图形布局编辑器损坏

我甚至尝试重新安装Eclipse和Android插件，但无济于事。在网上找不到任何东西，恐怕。其他人有相同的问题或建议吗？

原来，这不仅仅是一个Mac问题。同样的问题发生在我的Linux机器上。 – Tim 2011-01-27 11:02:28

第一次打开布局xml文件，然后单击“图形布局”选项卡时，仍存在问题。它从不自动显示。您仍然需要在下拉框（位于“创建”按钮下方）之间切换两个Android版本，才能显示GUI。非常刺激。 – Tim 2011-04-15 10:02:57
