禁用操作栏的默认背景并添加自定义背景

Question

我想将自定义背景添加到AppCompat操作栏。这是我的风格

<!-- 
    Base application theme, dependent on API level. This theme is replaced 
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices. 
--> 
<style name="AppBaseTheme" parent="Theme.AppCompat.Light"> 
    <item name="android:actionBarStyle">@style/MyActionBar</item> 
    <!-- 
     Theme customizations available in newer API levels can go in 
     res/values-vXX/styles.xml, while customizations related to 
     backward-compatibility can go here. 
    --> 
</style> 

<!-- Application theme. --> 
<style name="AppTheme" parent="AppBaseTheme"> 
    <!-- All customizations that are NOT specific to a particular API-level can go here. --> 
</style> 

<!-- ActionBar styles --> 
<style name="MyActionBar" parent="Theme.AppCompat.Light.DarkActionBar"> 
    <item name="android:background">@drawable/top_bar_bg</item> 
</style> 

我使用AppTheme我的主题。它仍然显示默认的黑暗背景。我在这里错过了什么？
