Android 动态扩展屏幕 - 从一张图表开始，然后添加更多图表。或多个连接的屏幕
我很难找到如何实施我的一些课程作业。
我想根据客户的概念制作一个应用程序，它是一个思维导图应用程序，允许用户处理图表以阐述想法。
我理想地想要的是一种从一个基本图表开始的方法，其形状是固定的，并且能够添加更多的“连接”图表。
现在图表部分不是问题，但是我怎样才能使这个应用程序与每个图表连接一起工作？
理想的情况是 -
- 用户可以启动一个“项目”[项目由一个或多个链接的图表组成]
- 用户可以在初始图表上工作，添加信息。
- 然后，用户可以向该项目添加另一个图表，例如通过点击屏幕上的按钮。
- 然后，用户将在屏幕上显示新的图表，该图表是空白的并准备好添加信息。
- 当用户有多个图表时，我希望当前项目中的其他图表出现在当前图表后面
- 我希望用户能够旋转通过图表，希望它们之间有一条连接线或生命线类型的东西
这可能有点模糊，粗体中的阶段是我所坚持的。
如果有人能好心地为我指出一些关于此类事情的阅读材料、教程等，我将非常感激！
提前致谢，
约翰
I'm having difficulty finding out how I could go about implementing some of my course-work.
I want to make an app, based on a client's concept, it's a mind mapping app that allows users to work on a diagram in order to elaborate ideas.
What I would ideally like is a way of starting with one basic diagram, the shape of which is fixed, and being able to add several more 'connecting' diagrams.
Now the diagram part is not a problem, but how could I make this app work with each diagram connecting?
An ideal scenario would be -
- A user can start a "project" [a project consists of one or more linked diagrams]
- The user can work on the initial diagram, adding information.
- The user can then add another diagram to this project, say-by hitting an on screen button.
- The user will then have the new diagram appear on screen, blank and ready to add information.
- When the user has more than one diagram, I would like the other diagrams within the current project to appear behind the current diagram
- I would like the user to be able to spin through diagrams and hopefully have a connecting line or lifeline type thing between them
This may be a bit vague, the stages in bold are what I am kind of stuck on.
If someone would be kind enough to point me in the direction of some reading material, tutorials etc on this kind of thing, I would be extremely grateful!
Thanks in advance,
JohnD

这似乎就是我想要的东西。
对于任何被多个活动/屏幕困扰的人。
在同一屏幕上显示多个 Activity

This seems to be the kind of thing I wanted.
For anybody who is stuck with multiple activities / screens.
Display multiple activities on same screen
