title: Android action bar overflow menu remove shadow
body: <p>I'd like to remove shadow around my action bar overflow menu, but i haven't found any attributes allowing that. I'm extending Theme.AppCompat.
   </p>
  
  <pre><code>&lt;!-- Base application theme. --&gt;
  &lt;style name="AppTheme" parent="Theme.AppCompat"&gt;
      &lt;!-- Customize your theme here. --&gt;
      &lt;item name="actionOverflowButtonStyle"&gt;@style/OverflowButton&lt;/item&gt;
      &lt;item name="actionOverflowMenuStyle"&gt;@style/OverflowMenu&lt;/item&gt;
      &lt;item name="actionBarStyle"&gt;@style/MyActionBarLogo&lt;/item&gt;
      &lt;item name="android:dropDownListViewStyle"&gt;@style/PopupMenuListView&lt;/item&gt;
      &lt;item name="dropDownListViewStyle"&gt;@style/PopupMenuListView&lt;/item&gt;
      &lt;item name="android:textColor"&gt;@color/black&lt;/item&gt;
      &lt;item name="android:popupMenuStyle"&gt;@style/PopupMenu&lt;/item&gt;
  &lt;/style&gt;
  &lt;style name="MyActionBarLogo" parent="Widget.AppCompat.ActionBar"&gt;
      &lt;item name="background"&gt;@color/white&lt;/item&gt;
      &lt;item name="displayOptions"&gt;useLogo|showHome&lt;/item&gt;
  
      &lt;item name="elevation"&gt;0dp&lt;/item&gt;
      &lt;item name="android:windowContentOverlay"&gt;@null&lt;/item&gt;
  &lt;/style&gt;
  &lt;style name="OverflowButton" parent="@style/Widget.AppCompat.ActionButton.Overflow"&gt;
      &lt;item name="android:src"&gt;@mipmap/menu_logo&lt;/item&gt;
  &lt;/style&gt;
  &lt;style name="OverflowMenu" parent="@style/Widget.AppCompat.PopupMenu.Overflow"&gt;
      &lt;item name="overlapAnchor"&gt;false&lt;/item&gt;
      &lt;item name="android:dropDownVerticalOffset"&gt;52dp&lt;/item&gt;
      &lt;item name="android:dropDownHorizontalOffset"&gt;10dp&lt;/item&gt;
  &lt;/style&gt;
  &lt;style name="PopupMenuListView" parent="@style/Widget.AppCompat.ListView.DropDown"&gt;
      &lt;item name="android:divider"&gt;@drawable/menu_divider&lt;/item&gt;
      &lt;item name="android:dividerHeight"&gt;1dp&lt;/item&gt;
      &lt;item name="android:textColor"&gt;@color/black&lt;/item&gt;
      &lt;item name="android:background"&gt;@color/white&lt;/item&gt;
  &lt;/style&gt;
  &lt;style name="PopupMenu" parent="@style/Widget.AppCompat.ListPopupWindow"&gt;
      &lt;item name="android:popupBackground"&gt;@color/white&lt;/item&gt;
  &lt;/style&gt;
