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 } ... } }
