android-由于支持ActionBar的类强制转换异常而无法启动活动

从一个android.support.v7.app.ActionBarActivity开始,我正在启动另一个android.support.v7.app.ActionBarActivity活动,但得到了以下异常：

FATAL EXCEPTION: main

第一次活动有风格

<style name="PS" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowActionBar">false</item>

    <item name="android:windowContentTransitions">true</item>
</style>

第二(崩溃的)：

<style name="PS.Second" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="android:actionBarStyle">@style/PS.ActionBar</item>

    <item name="android:windowNoTitle">false</item>
    <item name="android:windowActionBar">true</item>
</style>

任何想法如何避免ClassCastException？

解决方法:

我不确定什么是PS.ActionBar样式.所以我把它注释掉了.并在Device Moto G API 21上尝试了相同的操作.我看不到崩溃.

话虽如此,这次崩溃似乎是内部的.除了不推荐使用ActionBarActivity之外,还可以使用AppCompatActivity.

PS：我仍在等待您的答案,因此我可以使用更多发现来编辑答案.
