android：popupBackground不適用於上下文菜單

Question

爲什麼我的styles.xml代碼成功地更改了我的操作欄溢出菜單的背景顏色，但無法更改我的應用中上下文菜單的背景顏色？

<style name="AppBaseTheme" parent="Theme.AppCompat.Light"> 
    <!--<item name="android:actionBarStyle">@style/DarkActionBar</item> --> 

</style> 

<!-- Application theme. --> 
<style name="AppTheme" parent="AppBaseTheme"> 

    <!-- All customizations that are NOT specific to a particular API-level can go here. --> 
    <item name="android:popupMenuStyle">@style/MyPopupMenu</item> 
    <item name="android:itemTextAppearance">@style/MyCustomMenuTextAppearance</item> 

</style> 

<!-- Popup Menu Background Color styles --> 
<!-- <style name="MyPopupMenu" parent="@android:style/Widget.Holo.ListPopupWindow"> --> 
<!-- <style name="MyPopupMenu" parent="@android:style/Widget.PopupMenu"> --> 
<style name="MyPopupMenu" parent="@style/Widget.AppCompat.PopupMenu"> 
    <item name="android:popupBackground">@color/dark_gray</item> 
</style> 
<!-- Popup Menu Text Color styles --> 
<style name="MyCustomMenuTextAppearance"> 
    <item name="android:textColor">@color/white</item> 
</style> 

我一直堅持這個幾個小時，沒有類似的問題對我的解決方案。

如果有幫助，這裏是創建上下文菜單我的Java代碼：

@Override 
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { 
    super.onCreateContextMenu(menu, v, menuInfo); 

    AdapterView.AdapterContextMenuInfo info = 
      (AdapterView.AdapterContextMenuInfo) menuInfo; 
    String selectedWord = ((TextView) info.targetView).getText().toString(); 
    menu.setHeaderTitle(selectedWord); 

    MenuInflater inflater = getActivity().getMenuInflater(); 
    inflater.inflate(R.menu.shopping_list_name_context, menu); 
} 

而且，爲了完整起見，這裏是我的上下文菜單XML，shopping_list_name_context.xml：

<item android:id="@+id/rename_shopping_list" 
     android:icon="@drawable/ic_action_edit" 
     android:title="@string/rename_shopping_list" /> 

<item android:id="@+id/empty_shopping_list" 
     android:icon="@drawable/ic_action_discard" 
     android:title="@string/empty_shopping_list" /> 

<item android:id="@+id/delete_shopping_list" 
     android:icon="@drawable/ic_action_discard" 
     android:title="@string/delete_shopping_list" /> 

而且，作爲r equested，這裏是我的AndroidManifest.xml的摘錄：

<uses-sdk 
    android:minSdkVersion="14" 
    android:targetSdkVersion="21" /> 

<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />  
<uses-permission android:name="android.permission.GET_ACCOUNTS" /> 
<uses-permission android:name="android.permission.USE_CREDENTIALS" /> 
<uses-permission android:name="android.permission.WAKE_LOCK" /> 
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> 

<supports-screens  
    android:smallScreens="true" 
    android:normalScreens="true" 
    android:largeScreens="true" 
    android:xlargeScreens="true" /> 

<permission 
    android:name="com.example.myapp.permission.C2D_MESSAGE" 
    android:protectionLevel="signature" /> 

<uses-permission android:name="com.example.myapp.permission.C2D_MESSAGE" /> 
<uses-permission android:name="com.android.vending.BILLING" /> 

<application 
    android:name=".MyApplication" 
    android:allowBackup="true" 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name_short" 
    android:theme="@style/AppTheme" 
    android:largeHeap="true" > 

Answer 1

你需要覆蓋actionModeBackground這樣的：

<item name="android:actionModeBackground">@drawable/context_menu</item> 

可能重複的問題：Override context menu colors in Android

Answer 2

下面是代碼在上下文菜單中設置背景，它的作用就像魅力。

在styles.xml文件把下面的代碼：

<!-- Application theme. --> 
<style name="AppTheme" parent="AppBaseTheme"> 

    <item name="android:itemBackground">@android:color/holo_green_dark</item> 

</style> 

Answer 3

嘗試添加此：

<item name="android:popupBackground">@android:color/white</item> 

我希望它能幫助！

Answer 4

在您的應用程序欄XML：

app:popupTheme="@style/MyCustomOverflowTheme" 

然後在您的styles.xml：

<style name="MyCustomOverflowTheme" parent="Theme.AppCompat.Light"> 
    <item name="android:textColorPrimary">@color/primaryColor</item> 
    <item name="android:textColorSecondary">@color/accentColor</item> 
    <item name="android:background">@color/accentColor</item> 
</style> 

編輯

app:popupTheme="@style/MyCustomOverflowTheme" 

應該去爲你的工具欄或動作條財產，例如：

<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:background="@color/primaryColor" 
    app:theme="@style/MyCustomToolBarTheme" 
    app:popupTheme="@style/MyCustomOverflowTheme" 
    > 
</android.support.v7.widget.Toolbar> 

Answer 5

您是否嘗試在您的ActionBar主題中放置「android：actionModeBackground」？

<style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar"> 
    <!-- main theme --> 
    ..... 
    <item name="actionBarStyle">@style/AppTheme.ActionBar</item> 

    <!-- if you're using Toolbar you have to put this --> 
    <item name="windowActionModeOverlay">true</item> 

</style> 

<style name="AppTheme.ActionBar" parent="Theme.AppCompat.Light"> 
     ..... 
    <item name="android:actionModeBackground">@color/theme_ambiance_dark</item> 
     ..... 
</style>
