如何在不创建新活动的情况下更新活动的内容？
我正在尝试制作一个应用程序，并且为特定活动制作了蓝图，但我不知道该如何实施它。布局在活动顶部包含几个按钮，每个按钮都具有一些信息，这些信息显示在视图内部。按钮下存在需要更新的视图。我不希望更改活动，而应该更新视图的内容，每个类别/按钮都不同。
通过进行一些研究，我意识到可以使用“标签布局”来达到我的要求，但是我不想要选项卡，我需要一些时尚的按钮作为替换。
我知道我不是最好的描述，所以我已经看过运球，发现了一种与蓝图相似的100％的设计。
我想使用Android Studio使用XML和Java实现此目标！每个建议将是我的应用程序的一个很好的支持Foy。
多谢。
I'm trying to make an app and I have made a blueprint for a specific activity, but I don't know how to implement it. The layout contains few buttons at the top of the activity, and each button features some information, which is displayed inside the view. The view which needs to be updated is present under the buttons. I don't want the activity to be changed, instead it should update the contents of the View, which is different for each category/button.
By doing some research I have realised that the "Tab Layout" can be used to achieve my requirements, but I don't want the tabs and I need some stylish buttons as a replacement.
I know I'm not the best at describing, so I have looked upon Dribble and found one design which is 100% similar to blueprint.
I want to achieve this using XML and Java using Android Studio! Every suggestion will be a great support foy my app.
Thanks a lot.

据我所知，您可以通过使用片段来实现这一点（这与您在Tableayout上使用的概念相同）。我真的不知道您在Android上拥有多少知识，但是如果您知道片段是什么，那么您可以很容易地重新创建这个想法。
您有3个针对3个不同片段的按钮，因此您必须通过分开设计每个片段，并根据单击的按钮更改它。
As far as I know, you could achieve that by using fragments (which is the same concept you would have used on TabLayout). I don't really know how much knowleadge you have on Android, but if you know what a Fragment is, it should be easy for you to recreate the idea.
You have 3 buttons for 3 different fragments, so you must design every fragment by separate and change it depending the button you click.
