adding importantForAccessibility for Text, Button, ImageBackground (f…
…acebook#34245) Summary: Previously published by [grgr-dkrk][2] as [https://github.com/facebook/react-native/issues/31296][3], fixes the following issues: 1) ImportantForAccessibility="no" does not work on Text, Button 2) ImportantForAccessibility="no-hide-descendants" does not work on Text, Button, or ImageBackground. Note: On ImageBackground, focus is prevented on the imageBackground node itself, but focus is not prevented on its descendants. Note: [Button component expected behavior for prop importantForAccessibility][4] >Some components like Button seem like atomic units, but they end up rendering a hierarchy of components for example a wrapper View with a Text inside them. Allowing those descendants to become focusable, breaks the model of these being a single component to consider and forcing no-hide-descendants makes sense here. >The other option is always to render any descendants of these elements with importantForAccessibility="no", so they can never be focusable on their own. This would have the same result, **BUT may potentially cause issues when the descendant content is supposed to automatically get moved up to the focusable ancestor to act as a label** (which is what Talkback does with unfocusable text elements by default). Note: [importantForAccessibility="no" does not allow screenreader focus on nested Text Components with accessibilityRole="link" or inline Images][5] fixes facebook#30850 related facebook#33690 ## Changelog [Android] [Fixed] - adding importantForAccessibility for Text, Button, ImageBackground Pull Request resolved: facebook#34245 Test Plan: 1) testing ImageBackground importantForAccessiblity ([link to test][1]) 2) importantForAccessibility="no" does not allow screenreader focus on nested Text Components with accessibilityRole="link" or inline Images ([link to test][5]) 3) testing ImageBackground importantForAccessiblity ([link to test][6]) 4) Button with importantForAccessibility=no ([link to test][7]) [1]: facebook#31296 (comment) "" [2]: https://github.com/grgr-dkrk "grgr-dkrk" [3]: facebook#31296 "facebook#31296" [4]: facebook#31296 (comment) "expected behaviour with prop importantForAccessibility in Button component" [5]: facebook#30850 (comment) "importantForAccessibility=no does not allow screenreader focus on nested Text Components with accessibilityRole=link or inline Images" [6]: facebook#34245 (comment) "testing ImageBackground importantForAccessiblity" [7]: facebook#34245 (comment) "Button with importantForAccessibility=no" Reviewed By: cipolleschi Differential Revision: D38121992 Pulled By: dmitryrykun fbshipit-source-id: 368b4dcb47d7940274820aa2e39ed5e2ca068821
