In order to create an accessible application that still utilizes TabWidget functionality, Deque developers created a custom TabWidget layout, which extends a LinearLayout, to use instead of the default Android TabWidget. This behavior means default TabWidgets violate WCAG 2.0 success criteria. To a TalkBack user, there is no difference between this TabWidget and a TextView. There is nothing that indicates the highlighted view has any functionality whatsoever. Try it on the “broken” page – all that is announced is “Cat,” “Dog,” or “Fish.” A non-sighted user would not be able to tell that the highlighted element is a tab. It also does not announce it’s role – that it is a tab. It does not announce it’s state – whether the tab is selected or not – nor where the current tab lies in the entire TabWidget (for example, tab # of #). When a tab is highlighted using TalkBack in Android, the default announcement is only the text (if any) in the current tab. The following discussion will refer to the broken tab view as well as the fixed tab view. Before continuing find the “Tabbed Navigation” story, located in the main menu, and navigate to the broken tab. The Open Source app is the preferred reference. You can also find our app on the Google Play Store, though the version released may be behind the version referenced in the open source repository. Please get this running on your device and turn TalkBack on. This discussion references our open source app. In order to make TabWidgets accessible, developers must make some programmatic customizations. This is especially true for TabWidgets in Android because they are inaccessible otherwise. WCAG 4.1.2 describes the need for all user interface components to have a name, role, and value to ensure that assistive technology users have the necessary information to navigate screens effectively. TabWidgets are a tool that can add great functionality to your mobile Android apps however, they are inaccessible by default.
