talkback

问题 I have a nestedscrollview within my layout which contains few texts, buttons and recyclerviews. When talkback is on, I am able to traverse through all elements. But I face an issue. When my horizontal recyclerview is scrolled and then I swipe to hear the talkback, the focus moves to the toolbar first item. Then I need to traverse through all the visible items to reach to the horizontal scrollview scrolled item. This issue arises only for recyclerviews within nestedscrollview. My

问题 I'm using the ref prop along with findNodeHandle on a bunch of components in order to be able to trigger AccessibilityInfo.setAccessibilityFocus . However, it's not always working as expected. Sometimes the reference is null even though componentDidMount has executed. I'm often using setAccessibilityFocus in order to focus the header of a new element which appears on the screen, for example when opening a modal. IMPORTANT: This is Voiceover/Talkback functionality so you'll need to have that

问题 I'm implementing Accessibility in my application. Here's the scenario : I have 4 buttons arranged horizontally at the very top of the screen (Activity). On the click of a button, I'm launching an Alert Dialog which displays something to the user. With the alert being displayed, I will still be able to perform click operations on those 4 buttons at the top of the screen. When I turn ON TalkBack (Android Accessibility Service) in Android device and click on that button, alert is getting
