在操作欄上按下時如何更改項目的背景色？

Question

我正在Android上進行開發，但尚未找到一種方法來更改操作欄中項目的背景顏色。 我找到了與Sherlock和holo有關的方法，但仍然找不到它。 我正在使用此AppCompat和我的styles.xml文件

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

您需要設置“ ActionButton”的樣式。

<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>

我應該注意，您使用的drawable應該是StateListDrawable 。
