问题
我正在开发一个物业列表应用程序，用户可以列出他们的房间等物业。现在我面临的问题是在"更新列表详情"部分。基本上，我们有四个片段，用户通过这些片段填写他们的物业详情，最后将其发布到我们的平台上。现在，当用户想要更改他们的物业列表详情时，用户必须通过相同的四个片段来更新他们的物业详情。在这里，我遇到的问题是，当用户点击"更新列表按钮"时，第一个片段会打开，其中包含用户在列出他们的物业时之前选择的芯片组，现在我希望芯片组应该显示用户在列出他们的物业时选择的芯片。我不知道该如何做到这一点，请指导我。
这是列出物业的第一个片段的图片，如我们所见，它不显示用户在列出物业时选择的芯片：

从托管片段的活动中获取共享的 ViewModel 数据，将其作为生命周期所有者。
例如：val ViewModel: MainActivityViewModel by activityViewModels
然后设置第一个片段以观察所选属性。
由于数据的来源保持不变，您可以操作如何从中显示所选项目。
英文:
Take the data from a shared ViewModel with the Activity which houses the fragments as a lifecycle owner.
eg: val ViewModel:MainActivityViewModel by activityViewModels
Then set the first fragment to observe the selected properties .
Since the source of your data remains the same you can manipulate how to show the selected items from there
