android studio创建一个工程时候报错

最近下了android studio,创建第一工程时候就报错(如下):

 Rendering Problems The following classes could not be instantiated:
- android.support.v7.internal.widget.ActionBarOverlayLayout (Open Class, Show Exception, Clear Cache)
 Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE  Exception Details java.lang.ClassNotFoundException: android.support.v4.view.ViewPropertyAnimatorListener Copy stack to clipboard

从上面信息感觉是库文件缺少,最后弄了很久,才明白,其实问题很简单:在你工程文件style.xml中的代码有问题:

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>

应该在Theme前面加上Base.

    <!-- Base application theme. -->
    <style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
        <!-- Customize your theme here. -->
    </style>
