上面是我在项目里引入Material主题的代码，我想自己设置一下ActionBar的背景色，但发现这属性没起作用？有知道原因的吗？谢谢！

     <style name="AppTheme" parent="android:Theme.Material.Light">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="android:statusBarColor">@color/colorPrimaryDark</item>
        <item name="android:textColorPrimary">@color/colorAccent</item>
        <item name="android:windowBackground">@color/background</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>

You posted the above, I tried it and it works. . The following is the official document

 <style name="AppTheme" parent="android:Theme.Material.Light">
        <item name="android:colorPrimary">@color/colorPrimary</item>
        <item name="android:colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="android:colorAccent">@color/colorAccent</item>
    </style>

ActionBar is defined by the android:colorPrimary attribute, please check again
Also, the color of the status bar is best to use the android:colorPrimaryDark attribute
