React Native - What is reactTag parameter in AccessibilityInfo.setAccessibilityFocus()?

由 杀马特。学长 韩版系。学妹 提交于 2021-02-08 15:16:35

React native documentation don't provide any information about this parameter: Set accessibility focus to a React component. On Android, this is equivalent to UIManager.sendAccessibilityEvent(reactTag, UIManager.AccessibilityEventTypes.typeViewFocused);. I don't have any background of Objective-C and Java . A little example will be more appreciated. Thank !!! 回答1: reactTag is simply a number that is used
