Selected State does not annonce when TextInput Component selected (#3…
Browse files Browse the repository at this point in the history
…1144)

Summary:
This issue fixes #30955 and is a follow up to pr #24608 which added the basic Accessibility functionalities to React Native.

TextInput should announce "selected" to the user when screenreader focused.
The focus is moved to the TextInput by navigating with the screenreader to the TextInput.

This PR adds call to View#setSelected in BaseViewManager https://developer.android.com/reference/android/view/View#setSelected(boolean)
The View#setSelected method definition https://github.com/aosp-mirror/platform_frameworks_base/blob/master/core/java/android/view/View.java
```java
/**
 * Changes the selection state of this view. A view can be selected or not.
 * Note that selection is not the same as focus. Views are typically
 * selected in the context of an AdapterView like ListView or GridView;
 * the selected view is the view that is highlighted.
 *
 * param selected true if the view must be selected, false otherwise
 */
public void setSelected(boolean selected) {
  if (((mPrivateFlags & PFLAG_SELECTED) != 0) != selected) {
    // ... hidden logic
    if (selected) {
      sendAccessibilityEvent(AccessibilityEvent.TYPE_VIEW_SELECTED);
    } // ... hidden logic
  }
}
```

VoiceOver and TalkBack was tested with video samples included below.
