title: Setting content description for option menu android Talkback
body: <p>I am implementing "<code>Read Aloud</code>" or "<code>Talkback</code>" for an app. Everything is working with <code>contentDescription</code> text, but with option menu, I found nothing related to <code>contentDescription</code>, I want system read <code>"Menu "+ item's name</code>.</p>
  
  <p>EX: My menu has 2 items: "<strong>Create New Folder</strong>" and "<strong>Delete current folder</strong>", currently, when I focus a menu item (Support trackball and bluetooth key), system can talk exactly the menu's text. But I want it talks more like "<strong><em>1: Menu Create New Folder</em></strong>" and "<strong><em>2: Menu Delete current folder</em></strong>". </p>
  
  <p>So, How can I change the read text? How can I get the focused <code>menu item</code> when bluetooth keyboard press <code>UP/DOWN</code> key?</p>
