如果您在ActionBarActivity中展开MainActivity，则还必须更改values-v11中的父主题。因此值-v11中的style.xml将为 -

 <!-- res/values-v11/themes.xml -->
 <?xml version="1.0" encoding="utf-8"?>
 <resources>
    <style name="QueryTheme" parent="@style/Theme.AppCompat">
    <!-- Any customizations for your app running on devices with Theme.Holo here -->
    </style>
 </resources>

AndroidManifest.xml中的

 <activity
        ...
        android:theme="@style/Theme.AppCompat" />

无法在设备和模拟器上运行Android项目
