Question

所以我有一个包含其他相对布局的相对布局。子布局包含我正在从JSON对象解析的各种信息（其具有键/值以及具有子键/ val对象的子JSON数组）。用户通过列表片段导航到每个根JSON对象，该片段片段显示详细信息片段。根详细信息（名称，图像，描述等）显示效果很好。

层次结构：

委员会：

名称
图像
描述
成员：JSON对象数组

成员： - 名称 - 国家 - 图像

这是布局文件：

我正在尝试使用相对布局参数动态地将成员“堆叠”在一起。问题是在片段中创建的新视图的id是在运行时生成的。是否有可能将它们“堆叠”起来就好像它们是列表视图一样，或者我最好通过使用实际的列表视图/适配器组合去另一条路线，或者甚至敢说...一个tableview？

提前致谢SO偷看！：）
