Question #4 Topic 1

In general, you should send an AccessibilityEvent whenever the content of your custom view changes. For example, if you are implementing a custom slider bar that allows a user to select a numeric value by pressing the left or right arrows, your custom view should emit an event of type TYPE_VIEW_TEXT_CHANGED whenever the slider value changes. Which one of the following sample codes demonstrates the use of the sendAccessibilityEvent() method to report this event.

  • A. override fun dispatchPopulateAccessibilityEvent(event: AccessibilityEvent): Boolean { return super.dispatchPopulateAccessibilityEvent(event).let { completed -> if (text?.isNotEmpty() == true) { event.text.add(text) true } else { completed } } }
  • B. override fun onKeyUp(keyCode: Int, event: KeyEvent): Boolean { return when(keyCode) { KeyEvent.KEYCODE_DPAD_LEFT -> { currentValue-- sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_TEXT_CHANGED) true } ... } }
  • C. override fun onKeyUp(keyCode: Int, event: KeyEvent): Boolean { return when(keyCode) { KeyEvent.KEYCODE_ENTER -> { currentValue-- sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_CONTEXT_CLICKED) true } ... } }
