Answer 1

You also need to override http://developer.android.com/reference/android/view/View.html#onInitializeAccessibilityNodeInfo(android.view.accessibility.AccessibilityNodeInfo)

and set the contentDescription there.

If you want to remove the 0%, I would try to change the class in AccessibilityNodeInfo/AccessibilityEvent: http://developer.android.com/reference/android/view/accessibility/AccessibilityNodeInfo.html#setClassName(java.lang.CharSequence)

Answer 2

I believe that this is a bug in TalkBack, and have raised Google Eyes-Free issue #375, including example code.
