覆盖 Android 中的上下文菜单颜色 [英] Override context menu colors in Android

问题描述

让我们看看，

我知道如何更改 ListView 的样式(选择项目时的橙色):

i know how to change the style of a ListView (the orange color when an item is selected):

android:listSelector="@drawable/xxx" 和一个带有位图或 @color 的 drawable

android:listSelector="@drawable/xxx" and a drawable with a bitmap or a @color

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:drawable="@drawable/image" />
    <item android:drawable="@android:color/transparent" />  
</selector> 

问题是，为了有一个连贯的设计，我必须对上下文菜单做同样的事情，但我看不到在哪里改变它.没有 listSelector，没有什么可改变的.

The thing is, in order to have a coherent design, i have to do the same thing for a context menu but i just can't see where to change it. There is no listSelector, nothing to change.

推荐答案

如果上下文菜单是指长按的菜单，那么我已使用以下代码完成此操作.我的菜单有我的主题背景和绿色突出显示.

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.

上下文菜单布局:

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

styles.xml，我在其中使用自定义主题(我认为这是关键)

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>
