【中文标题】l 不同设备内有RelativeLayout问题【英文标题】：l have RelativeLayout Problem within different devices 【发布时间】：2020-04-29 08:17:09 【问题描述】：

以下是我的 recyclerView 单元格 xml 布局及其显示方式的屏幕截图它在某些设备上显示对齐，但在其他设备上显示未对齐，并且未显示 list_consultation_section_two 并且 list_consultation_section_three 无缘无故居中任何想法为什么会发生这种情况？

</RelativeLayout>

它适用于 Xiaomi Redmi Note 8 (API 28)、OPPO A3fW (API 22)（完全不同的 API 版本）并且不适用于联想 tab-7504x (API 24)

如果我为 list_consultation_section_three 设置固定大小，我知道它在所有设备上都可以正常工作的解决方案但我只是想明白为什么？ ]

尝试制作 list_certificate_item_parent LinearLayout 而不是 RelativeLayout 并赋予它权重，试试下面的这段代码
