For anyone who (like me) doesn't enjoy playing around with 9-patch images, you can get the divider at the bottom of the action bar using an xml drawable:
对于那些（像我一样）不喜欢玩 9-patch 图像的人，您可以使用 xml drawable 获取操作栏底部的分隔符：
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Bottom Line -->
<item>
<shape android:shape="rectangle">
<solid android:color="@color/action_bar_line_color" />
</shape>
</item>
<!-- Color of your action bar -->
<item android:bottom="2dip">
<shape android:shape="rectangle">
<solid android:color="@color/action_bar_color" />
</shape>
</item>
</layer-list>
Save this as drawable/action_bar_background.xml, Then apply it in your theme:
将其保存为 drawable/action_bar_background.xml，然后将其应用到您的主题中：
<style name="Widget.MyTheme.ActionBar" parent="Widget.Sherlock.ActionBar">
<item name="android:background">@drawable/action_bar_background</item>
<item name="background">@drawable/action_bar_background</item>
</style>

The blue divider is the background by default. It's a 9-patch drawable which will ensure the line always appears at the bottom of the action bar regardless of its height.
默认情况下，蓝色分隔线是背景。它是一个 9-patch drawable，可确保线条始终出现在操作栏的底部，无论其高度如何。
For your situation I would copy the default background .pngs from Android and then modify them so that the expandable section of the 9-patch is your target background color. This will fill the action bar with your desired color while maintaining the blue border at the bottom.
对于您的情况，我会.png从 Android复制默认背景，然后修改它们，以便 9-patch 的可扩展部分是您的目标背景颜色。这将用您想要的颜色填充操作栏，同时保持底部的蓝色边框。

Just an update on the answer provided by DanielGrech. It's also possible to use your own custom graphic at the bottom of the actionbar. Like this:
只是对 DanielGrech 提供的答案的更新。也可以在操作栏底部使用您自己的自定义图形。像这样：
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Bottom Line with custom graphic instead of a solid color-->
<item android:drawable="@drawable/bar">
<shape android:shape="rectangle"/>
</item>
<!-- Color of your action bar -->
<item android:bottom="2dip">
<shape android:shape="rectangle">
<solid android:color="@color/action_bar_color" />
</shape>
</item>
</layer-list>
