Question

为了我的生命。我无法在模拟时应用此自定义弹出式样式。它只显示默认的Theme.AppCompat.Light.DarkActionBar弹出式菜单，其中包含浅色背景，无论我做什么。

任何人都有任何想法？

我已经尝试过这个表单中的多个答案。如果我的代码下面为此，我创建了一个虚拟应用程序来测试此功能。我已经确认所有的drawable都正确标记并存在。

的AndroidManifest.xml：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.erasedforprivacy.www.actionbarcolortest" >

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/Theme.Example" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

我认为你没有使用合适的父母。试试这个：

<style name="Theme.Example" parent="@style/Theme.AppCompat.Light.DarkActionBar">
    ....
    <item name="android:popupMenuStyle">@style/PopupMenu.Example</item>
    ....
</style>

<style name="PopupMenu.Example" parent="@android:style/Widget.PopupMenu">
    <item name="android:popupBackground">@drawable/menu_dropdown_panel_example</item>
</style>

并且不要忘记在Manifest中应用这种风格：

<application
   ....
   android:icon="@drawable/ic_launcher"
   android:label="@string/app_name"
   android:theme="@style/Theme.Example" >
   ....
</application>

无法将自定义主题应用于弹出菜单
