Android GridLayout出现错误，应用程序崩溃

我对布局非常陌生，但我成功地制作了一个非常好看的布局（对于平板电脑）。在Eclipse中，它工作得非常好。我用安卓4.0（ICS）上的“target”实现了这一切，但显然我的平板电脑只运行3.0（蜂巢）。当我意识到错误时，我将查看器/编辑配置更改为3.2，但Eclipse甚至不再显示布局的图形，它只是简单地吐出：

com.android.layoutlib.bridge.MockView cannot be cast to android.view.ViewGroup
    Exception details are logged in Window > Show View > Error Log
    The following classes could not be found:
    - GridLayout (Change to android.widget.GridLayout, Fix Build Path, Edit XML)

将弹出错误日志：

使用选择的2.3重新制作整个布局会解决此问题吗？这太糟糕了…

网格布局是在Android 4.0中引入的。你不能在3.0或3.2中使用它。

既然冰淇淋三明治的来源变得可用，我想看看是否有可能在4.0之前使用新引入的GridLayout。这确实是可能的。请访问我的博客帖子

Baahh！！那真糟糕。谢谢
