在操作栏上按下时如何更改项目的背景色？

Question

I'm developing on Android, and I have not yet found a way to change the background color of an item in the action bar. I found ways to do with Sherlock and holo but still I can not find it working. I'm using this AppCompat and my styles.xml file

<?xml version="1.0" encoding="utf-8"?>
<resources>

<style name="AppTheme" parent="@style/Theme.AppCompat.Light.DarkActionBar">
    <item name="actionBarItemBackground">@drawable/selectable_background_apptheme</item>
    <item name="popupMenuStyle">@style/PopupMenu.Apptheme</item>
    <item name="dropDownListViewStyle">@style/DropDownListView.Apptheme</item>
    <item name="actionBarTabStyle">@style/ActionBarTabStyle.Apptheme</item>
    <item name="actionDropDownStyle">@style/DropDownNav.Apptheme</item>
    <item name="actionBarStyle">@style/ActionBar.Solid.Apptheme</item>
    <item name="actionModeBackground">@drawable/cab_background_top_apptheme</item>
    <item name="actionModeSplitBackground">@drawable/cab_background_bottom_apptheme</item>

You need to style the 'ActionButton'.

<style name="Widget.AppCompat.ActionButton.AppTheme"
       parent="Widget.AppCompat.Light.Base.ActionButton">
    <item name="android:background">@drawable/your_background</item>
    <item name="background">@drawable/your_background</item>
</style>

<style name="ActionBar.Solid.Apptheme" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
    //Add this line
    <item name="actionButtonStyle">@style/Widget.AppCompat.ActionButton.AppTheme</item>

    <item name="background">@drawable/ab_solid_apptheme</item>
    <item name="backgroundStacked">@drawable/ab_stacked_solid_apptheme</item>
    <item name="backgroundSplit">@drawable/ab_bottom_solid_apptheme</item>
    <item name="progressBarStyle">@style/ProgressBar.Apptheme</item>

    //Add this line
    <item name="android:actionButtonStyle">@style/Widget.AppCompat.ActionButton.AppTheme</item>

    <item name="android:background">@drawable/ab_solid_apptheme</item>
    <item name="android:backgroundStacked">@drawable/ab_stacked_solid_apptheme</item>
    <item name="android:backgroundSplit">@drawable/ab_bottom_solid_apptheme</item>
    <item name="android:progressBarStyle">@style/ProgressBar.Apptheme</item>

I should note that the drawable you use should be a StateListDrawable .
