我想用一个非常简单的方法构建一个小部件GridLayout，但我得到了一个 InflateException：

Binary XML file line #2: Error inflating class android.widget.GridLayout

只发生在 4.0 和 4.2 上是没有问题的（版本之间有区别吗？）有人知道吗？

RemoteView仅允许某些布局在其内容中膨胀，您可以在此处查看列表

例如，您可以看到不允许使用TableView 。您的 logcat 消息说不允许使用GridView ，而文档说是。我猜这个功能是相当新的，它在 4.2 之前的版本上是不允许的。或 4.1。

您可能应该在远程视图中使用另一种布局类型。
