如何自定义菜单项的背景色? [英] How do I customize menu item's background color?

问题描述

我正在尝试自定义Toolbar的弹出菜单.现在我无法设置菜单项的背景颜色.

I'm trying to customize Toolbar's popup menu. Now I can not set background color of menu item.

我的styles.xml看起来像这样:

My styles.xml looks like this:

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme.NoActionBar" parent="@style/Theme.AppCompat.Light.DarkActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>

        <item name="android:actionBarStyle">@style/AppTheme.ActionBar</item>
        <item name="android:actionMenuTextColor">@color/actionbar_text_color</item>
        <item name="android:dropDownListViewStyle">@style/AppTheme.DropDown</item>
        <item name="android:itemTextAppearance">@style/menuItemColor</item>

        <!-- Support library compatibility -->
        <item name="actionBarStyle">@style/AppTheme.ActionBar</item>
        <item name="actionMenuTextColor">@color/actionbar_text_color</item>
        <item name="dropDownListViewStyle">@style/AppTheme.DropDown</item>
        <item name="itemTextAppearance">@style/menuItemColor</item>
    </style>

    <style name="AppTheme.ActionBar" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">\
        <item name="titleTextColor">@color/actionbar_text_color</item>
        <item name="subtitleTextColor">@color/actionbar_text_color</item>

        <item name="android:background">@color/actionbar_background</item>

        <!-- Support library compatibility -->
        <item name="background">@color/actionbar_background</item>
    </style>

    <style name="AppTheme.DropDown" parent="@style/Widget.AppCompat.Light.ListView.DropDown">
        <item name="android:background">@color/background_color</item>
        <!-- Support library compatibility -->
        <item name="background">@color/background_color</item>
    </style>

    <style name="menuItemColor">
        <item name="android:textColor">@color/inactive_text_color</item>
    </style>

</resources>

我使用代码将ActionBar添加到活动布局中

I added ActionBar to activity layout with code

<android.support.v7.widget.Toolbar
    android:id="@+id/toolbar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:theme="@style/AppTheme.ActionBar"/>

注意:我使用的是AppCompat，而不是Holo或其他.

Note: I'm using AppCompat, not Holo or other.

推荐答案

您也必须像这样为Overflow Menu定义样式:

You have to define style for Overflow Menu too like this :

<!-- OverFlow menu Styles -->
<style name="PopupMenuListView" parent="@style/Widget.AppCompat.Light.ListView.DropDown">
    <item name="android:divider">@color/sp_red_500</item>
    <item name="android:dividerHeight">1dp</item>
    <item name="android:background">@color/white</item>
</style>

并在您的父主题样式(基本应用程序主题)中定义下拉菜单样式，如下所示:

and in your parent theme style( Base application theme.) define drop down menu style like this :

 <item name="dropDownListViewStyle">@style/PopupMenuListView</item>
