尝试使用滑动手势更改焦点和滚动时的ViewPager2 +辅助功能+对讲问题

@Override
public boolean onRequestSendAccessibilityEvent(ViewGroup host, View child, AccessibilityEvent event) {
    if (event.getEventType() == AccessibilityEvent.TYPE_VIEW_FOCUSED_CHANGED) {
        AccessibilityNodeInfo nodeInfo = getAccessibilityNodeProvider().createAccessibilityNodeInfo();
        if (nodeInfo != null) {
            nodeInfo.collectionItemInfo = new AccessibilityNodeInfo.CollectionItemInfo();
            // 设置 collectionItemInfo 的相关属性
            nodeInfo.recycle();
        }
    }
    return super.onRequestSendAccessibilityEvent(host, child, event);
}

viewPager2.registerOnPageChangeCallback(new ViewPager2.OnPageChangeCallback() {
    @Override
    public void onPageSelected(int position) {
        super.onPageSelected(position);
        // 更新辅助功能的焦点
        AccessibilityNodeInfo nodeInfo = getAccessibilityNodeProvider().createAccessibilityNodeInfo();
        if (nodeInfo != null) {
            nodeInfo.setFocusable(true);
            nodeInfo.setFocusableInTouchMode(true);
            nodeInfo.requestFocus();
            nodeInfo.recycle();
        }
    }
});
