Accessibility Callback - 当 talkback 读完通知时

Question

在某些用户操作中，我想在屏幕上显示一些 announcement，不久之后，我想将辅助功能焦点转移到 specifc view。

我可以做到，

 view!!.announceForAccessibility("some action failed.")
  Handler().postDelayed({
         specificView.requestFocus() 
    specificView.sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_FOCUSED)
   }, 1000)

但这只是一种解决方法。在某些情况下，当用户有 customized speaking rate 等

时，它可能会失败

Is there any way where we can get a callback when talkback finish with reading announcement?

Answer 1

我不确定它是否是正确的解决方案，但这对我有用。

 specificView.contentDescriotion = "text you need to annonce"
 specificView.requestFocus()
 specificView.sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_FOCUSED)
 Handler().postDelayed({
     specificView.contentDescriotion = "actual content description for that view"
 }, 300)

为您要关注的视图的内容描述发布公告。
