Question

我想使用非常简单的GridLayout构建一个小部件，但我收到了一个InflateException：

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

只发生在4.0和4.2上是没有问题的工作（版本之间有区别吗？）有人知道一些事情吗？

Answer 1

RemoteView 只允许在其内容中夸大某些布局，您可以看到列表here

例如，您可以看到不允许使用 TableView 。你的logcat消息说不允许 GridView ，而文档说它是。我想这个功能很新，并且不允许在4.2之前的版本上使用。或4.1。

您应该在远程视图中使用其他布局类型。
