Setting content description for option menu android Talkback

Question

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?

Answer 1

this answer post AndroidX

androidx.core.view.MenuItemCompat.setContentDescription(menuItem,  contentDescription)

Answer 2

It seems they just added the setContentDescription(CharSequence contentDescription) method to the MenuItem class on API 26 (Android O)

Answer 3

MenuItemCompat in the v4 support libraries has a

android.support.v4.view.MenuItemCompat.setContentDescription(MenuItem menuItem, CharSequence contentDescription) 

method for backwards compatibility on pre-Oreo devices.

Answer 4

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.

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