android – GridLayout给出错误,崩溃应用程序

我对布局很新,但我能够成功地制作一个非常好看的布局(对于平板电脑).在Eclipse中,它运行良好.我在Android 4.0(ICS)上使用’目标’完成了所有操作,但显然我的平板电脑只运行3.0(Honeycomb).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)

弹出错误日志：

将选择2.3重新制作整个布局修复此问题？太傻了……

解决方法:

GridLayout是在Android 4.0中引入的.你不能在3.0或3.2中使用它.
