Impact
People using TalkBack are most impacted. TalkBack can not activate more than one active control within another accessibility element.
Confirmation
- Turn on TalkBack
- Attempt to focus the control
- Attempt to activate the control
- One of the following will happen:
- Inaccessible: A different control is activated.
- Inaccessible: The control is activated, but its focus box contains another control.
- Inaccessible: Nothing happens.
- Accessible: The control is activated and is the only control in its focus box.
How to Fix
Avoid setting the importantForAccessibility property to no on all clickable views nested inside a layout. Views that can be accessed without assistive technology should be available to anyone using assistive technology.
