我在Android xml布局中出现如下错误：
Exception raised during rendering: <include /> can only be used inside of a ViewGroup
Exception details are logged in Window > Show View > Error Log
The following classes could not be found:
- android.support.v7.internal.widget.ActionBarOverlayLayout (Fix Build Path, Edit XML, Create Class)
现在，当我将AppTheme更改为Theme.Holo时，它的工作正常。 我想知道为什么会这样？
