Hi all. I'm working on an Android application where we have a custom view and draw everything on a Canvas. I've watched the Google I/O 2012 accessibility video that discusses this exact scenario and it gives some pointer on how to get started. I have however failed to make this work as I expected it to.
We're aiming to support this on Jellybean and up, so I'm trying to use the new level 16 APIs for this. Here is how it's currently setup. We override "public boolean dispatchHoverEvent(MotionEvent ev)" and send off an accessibility event of type TYPE_VIEW_HOVER_ENTER and fill the event with the text content of the virtual child (getText.add and content description). We also provide a AccessibilityNodeProvider and create the virtual hierarchy via createAccessiblityNodeInfo() callback (first the View.NO_ID where we add all the children, and then one callback for each child where we populate the virtual child info). Now, I get all the callbacks and it seems as if it should be working. However, with this approach, we get no accessibility focus nor any talkback when clicking anywhere in the custom view. By playing around, I changed the event type we send off from dispatchHoverEvent to be TYPE_VIEW_ACCESSIBILITY_FOCUSED instead, and now the custom view gains accessibility focus. However, it seems that the virtual views never get accessiblity focus and never gets turned to speech via talkback. In order to support the swipe navigations, etc, I would expect that they would gain this focus based on the bounds we give the node info for each child. I have found zero working examples of applications that use these new APIs, and debugged and played around for 2 days without any success. Could anyone give some pointers to proper examples, or any ideas on what might be missing? Have I misunderstood the function of the virtual views? Thank you in advance.
