我正在尝试在蜂窝上使用AppCompat actionBar，但我无法做到。它适用于API＆gt; = 14。
这是我的AppTheme：
<style name="AppTheme" parent="@style/Theme.AppCompat.Light">
<item name="android:actionBarStyle">@style/AppTheme.ActionBarStyle</item>
<item name="actionBarStyle">@style/AppTheme.ActionBarStyle</item>
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
<item name="android:textViewStyle">@style/RobotoTextViewStyle</item>
<item name="android:buttonStyle">@style/RobotoButtonStyle</item>
<item name="android:windowBackground">@color/background</item>
</style>
其他奇怪的事情是getActionBar()总是返回null。
我在Gingerbread上看到了同样的问题，但在Honeycomb上却没有。
这是我的目标API：

android:targetSdkVersion="19" />

感谢。
答案 0 :(得分：0)
如果你的min SDK是7-9，你的活动应该延长ActionBarActivity并使用getSupportActionBar()。
如果你的min SDK是10或更高，那么扩展Activity并使用常规的HOLO主题。
