华为折叠屏折叠状态下和展开状态下的问题

displayMetrics折叠下取的都是同一个对象，所以设置了后能正常生效。但是展开状态下这个displayMetrics每次取的对象都不一样。

Start by reproducing the reported displayMetrics behavior on a Huawei foldable in folded and expanded states, using the issue screenshot and description as the starting context. Trace where display metrics are obtained and updated, then verify that screen adaptation remains correct across both states; no source file or test is identified in the issue.
