Android - Material 设计 - 如何设置上下文菜单的背景颜色

Question

对于 ListView ，我有一个上下文菜单(在项目上)。如何设置(通过样式)上下文菜单的背景颜色？

在示例中，我使用了以下基本主题:

<style name="Base.Theme.Xyz" parent="Theme.AppCompat.NoActionBar">

Answer 1

只需按照以下步骤操作:

If by context menu you mean the menu from the long press, then I have done this with the following code. My menu has my theme's background, and a green highlight.

context menu layout:

<menu
  xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/resetConfirm" android:title="@string/actual_reset"></item>
</menu>

styles.xml, where I'm using a custom theme (which I think is the key)

 <style name="GradientLight" parent="@android:style/Theme.Light">
    <item name="android:windowBackground">@drawable/background</item>
    <item name="android:progressBarStyle">@style/progressBar</item>
    <item name="android:buttonStyle">@style/greenButton</item>
    <item name="android:buttonStyleSmall">@style/greenButton</item>
    <item name="android:listViewStyle">@style/listView</item>
    <item name="android:itemBackground">@drawable/menu_selector</item>
    <item name="android:spinnerStyle">@style/spinner</item>
</style>
<style name="listView" parent="@android:style/Widget.ListView.White">
 <item name="android:background">@drawable/background</item>
 <item name="android:listSelector">@drawable/list_selector_background_green</item>
</style>
