java在performAction（）中将\u滚动到\u位置，返回false AccessibilityService Android

Question

您好，我想使用AccessibilityService滚动到布局中的特定位置y

我尝试了几种方法，但只有AccessibilityNodeInfo.ACTION_SCROLL_FORWARD有效，而AccessibilityNodeInfo.AccessibilityAction.ACTION_SCROLL_TO_POSITION无效

我是这样用的。要改变什么才能让它工作

private AccessibilityNodeInfo findScroll(AccessibilityNodeInfo root) {
    if(root == null) return null;

    if(root.isScrollable())
        return root;

    for(int i=0; i<root.getChildCount(); i++) {
        if(root.getChild(i).isScrollable())
            return root.getChild(i);
    }
    return null;
}

AccessibilityNodeInfo scrollable = findScroll(getRootInActiveWindow());
            if (scrollable != null) {
                Bundle bundle = new Bundle();
                bundle.putInt(AccessibilityNodeInfo.ACTION_ARGUMENT_ROW_INT, 8);
                bundle.putInt(AccessibilityNodeInfo.ACTION_ARGUMENT_COLUMN_INT, 8);
                scrollable.performAction(AccessibilityNodeInfo.AccessibilityAction.ACTION_SCROLL_TO_POSITION.getId(), bundle);
            }
