uiautomator2版本号是：3.2.6
我导出来的xml结构如附件 1.txt 【请注意该文件是xml，由于github限制，请转换成xml文件】
我的代码是
driver = u2.connect("fb8bff0f")
# xml = driver.dump_hierarchy()
# print(xml)
# 通过 resource id 定位父节点
parent_node = driver(className="android.widget.ScrollView")
# 获取该节点下的所有一级子节点
children_nodes = parent_node.child()
print(len(parent_node))从xml中能够看到，该节点是
