回答1:

Add this to your toolbar element

app:popupTheme="@style/ThemeOverlay.YourApp"

Then in your styles.xml define the popup menu style

<style name="ThemeOverlay.YourApp" parent="ThemeOverlay.AppCompat.Light">
    <item name="android:colorBackground">@color/your_background_color</item>
    <item name="android:textColor">@color/your_text_color</item>
</style>

Note that you need to use colorBackground and never background. The latter would be applied to everything (the menu itself and each menu item), the former applies only to the popup menu.

Use android:popupBackground into styles.

like

<style name ="MyPopupMenu" parent="Theme.AppCompat.Light">
    <item name="popupMenuStyle">@style/MyPopupMenuStyle</item>
</style>

<style name="MyPopupMenuStyle">
    <item name="android:dropDownSelector">@drawable/abc_list_selector_holo_dark</item>
    <item name="android:popupBackground">@drawable/abc_menu_dropdown_panel_holo_dark</item>
    <item name="android:dropDownVerticalOffset">0dip</item>
    <item name="android:dropDownHorizontalOffset">0dip</item>
    <item name="android:dropDownWidth">wrap_content</item>
</style>
