Eclipse Android图形布局编辑器已损坏

Question

我在Mac上运行Eclipse Helios，刚刚更新到ADT 9.0.0。 它似乎打破了布局编辑器。 每当我尝试使用布局编辑器打开布局xml文件时，我都会收到错误。 编辑器有一个“缺少主题”消息，而生成的主要错误如下。

 Selecting page '0' in AndroidXmlEditor failed

我甚至尝试重新安装Eclipse和Android插件，但无济于事。我不敢在网上找到任何东西。 其他人有同样的问题或建议吗？

添

Answer 1

我现在偶然发现了同样的问题。 “config”部分似乎有一个新的下拉列表用于选择平台版本（在我的情况下没有选择）。选择任何（例如“Android 2.2”）使主题选择器出现，布局工作正常。

Answer 2

同样在这里，但我找到了一些东西。当我尝试使用时会出现问题 Google API作为项目构建目标。 如果我更改为Android 2.3，它会按预期工作

Answer 3

面临类似的错误。我无法在我的“图形布局”选项卡中看到任何图形布局预览。大多数下拉菜单都被阻止（灰显）。当我使用API​​级别9定位Google API 2.3.1时会发生这种情况。但另一方面，当我使用Android 2.3.1 API 9构建它时，一切正常。

Answer 4

我认为这是因为你使用的自定义布局组件。

我认为已经提交了一个错误。您可以提交另一个或投票支持现有的优先级

Answer 5

我在ADT 15.0.0版上遇到了同样的问题。将ADT更新为15.0.1后，一切正常。希望这也能解决你的问题。

Answer 6

在菜单栏中转到项目＆gt;清理选择“清除所有项目”，然后再次加载xml选择你的Android版本。

这应该做。如果没有，请尝试选择其他选项。

为我工作！

Answer 7

ADT 11于2011年6月6日发布。

从此链接安装插件。

我认为它的工作方式与我们预期的方式相同......
