try using theme.appcompat in styles.xml file. example this:

<?xml version="1.0" encoding="utf-8"?>  <resources> <!-- theme applied application or activity --> <style name="customactionbartheme" parent="@style/theme.appcompat.light.darkactionbar">     <item name="android:actionbarstyle">@style/myactionbar</item>      <!-- support library compatibility -->     <item name="actionbarstyle">@style/myactionbar</item> </style>  <!-- actionbar styles --> <style name="myactionbar" parent="@style/widget.appcompat.light.actionbar.solid.inverse">     <item name="android:background">@drawable/actionbar_background</item>      <!-- support library compatibility -->     <item name="background">@drawable/actionbar_background</item> </style>
