使用AppCompat Theme时,下面的代码可以帮助您.Kitkat或Lollipop

使你的style.xml如下所示

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/black</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="actionOverflowMenuStyle">@style/OverflowMenu</item>
</style>


<style name="OverflowMenu" parent="Widget.AppCompat.PopupMenu.Overflow">
    <item name="android:windowDisablePreview">true</item>
    <item name="overlapAnchor">false</item>
    <item name="android:dropDownVerticalOffset">5.0dp</item>
    <!--<item name="android:popupBackground">#FFF</item>-->
</style>

Answer 2

根据我的代码,这是通过改变风格的精确分配.

<style name="AppTheme" parent="@android:style/Theme.Holo.Light">
    <item name="android:actionBarStyle">@style/MyActionBar</item>
    <item name="android:actionMenuTextColor">@color/text_white</item>
    <item name="android:popupMenuStyle">@style/PopupMenu.Example</item>
    <item name="actionOverflowMenuStyle">@style/OverflowMenu</item>
</style>

<style name="PopupMenu.Example" parent="@android:style/Widget.Holo.Light.ListPopupWindow">
    <item name="android:popupBackground">#efefef</item>
</style>

<style name="OverflowMenu" parent="Widget.AppCompat.PopupMenu.Overflow">
    <!-- Required for pre-Lollipop. -->
    <item name="overlapAnchor">false</item>

    <!-- Required for Lollipop. -->
    <item name="android:overlapAnchor">false</item>
    <item name="android:dropDownVerticalOffset">4.0dip</item>

</style>

Answer 3

如果你想使用,以保持ActionBar和AppCompat主题,而不是ToolBar或Holo主题,您可以使用此代码:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="actionOverflowMenuStyle">@style/MyOverflowMenu</item>
</style>

<style name="MyOverflowMenu" parent="Widget.AppCompat.PopupMenu.Overflow">
    <item name="overlapAnchor">false</item>
    <item name="android:overlapAnchor" tools:ignore="NewApi">false</item>
    <item name="android:dropDownVerticalOffset">4.0dip</item>
</style>

这对我有用.
