Setting content description for option menu android Talkback

I am implementing "Read Aloud" or "Talkback" for an app. Everything is working with contentDescription text, but with option menu, I found nothing related to contentDescription, I want system read "Menu "+ item's name.

EX: My menu has 2 items: "Create New Folder" and "Delete current folder", 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 "1: Menu Create New Folder" and "2: Menu Delete current folder".

So, How can I change the read text? How can I get the focused menu item when bluetooth keyboard press UP/DOWN key?

Solution

  • As my investigation, in Android internal source code, class ActionMenuItemView.java method setTitle(CharSequence title), the source code also sets setContentDescription(title), so Android will read your MenuItem's text as default. I don't know why the core has so inflexible in this case.

    Thanks for @sofakingforever answer.

    Seem Google just added the setContentDescription(CharSequence contentDescription) method to the MenuItem class on API 26 (Android O).

    Updated: Thanks for new @tim.paetz answer . Look like all versions are now supported setContentDescription for menu item using android support v4 libraries.
