body: <p>Is it possible to perform a long press on a menu item to perform a certain action? 
  I'm trying to have a menu dropdown when I long press a certain item.</p>
  
  <p>Here's the menu xml</p>
  
  <p>
  </p>
  
  <pre><code>&lt;item
      android:id="@+id/add_item"
      android:icon="@drawable/ic_add_black_24dp"
      android:showAsAction="ifRoom"
      android:title="Add Item"&gt;
  &lt;/item&gt;
  
  &lt;item
      android:id="@+id/open_menu"
      android:icon="@drawable/ic_menu_black_24dp"
      android:showAsAction="ifRoom|withText"
      android:title="Open Menu"&gt;
  &lt;/item&gt;
  </code></pre>
