Android Studio 1.2.1.1 Rendering Problems

Rendering Problems

 The following classes could not be found:

- android.support.v7.internal.widget.ActionBarOverlayLayout

解决方法：

styles.xml

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

改为（加Base）

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