解决方案：

AndroidManifest.xml 工程的这个文件中，如果

 

        android:name=".v3.JCZApp"

        android:allowBackup="true"

        android:icon="@drawable/icon"

        android:label="@string/app_name"

        android:theme="@style/ThemeActivity" >

这部分，有指定了theme: ，我这里是   android:theme="@style/ThemeActivity" ，

然后查看详细的 @style/ThemeActivity 定义如下:

 

有的朋友点出了关键点：theme，就是主题定义，在这个style中，加上   parent="android:Theme" ,再运行，发现问题解决，改后的style如下：
