Single Activity with multiple fragments

I m new to Android development and stuck with design. I d like to design a single activity application with multiple fragments. But whatever I consider, I m stuck with design. I first considered fragments as components or widgets that I could organize where I wanted on my screen. But a single activity has only one xml view layout and can not find a solution.

Here is what I want.

UI design

The problems are the following.

  1. The layout choice: I need a layout for full screen fragment screen 1 but another splitted one for other screens.

  2. The keyboard: if I do a fullscreen fragment layout for all my screens with a (game-keyboard) fragment and (dico-keyboard) fragment, how do I remove the keyboard in dico fragment on tablets ? And can I share keyboard code between both fragments ?

I saw that calling setContentView during runtime is kinda annoying as you have to reassign your variables and is not suitable. All the applications I find are fullscreen single fragment on layout allowing libs like ViewPager. I can not find an example of composed screen with fragment components.

What layout would you chose, with what kind of fragments ? Or do you know a library that allow composing fragments as widgets on screen ? Thanks for your help.

Welcome to Android. Buckle up, it's going to be a bumpy ride.

First, you should spend some quality time with the Android Developer Guides.

Developer Guides | Android Developers

The insight for your particular challenge is that layouts are resources, and and you can have a layout resource that changes based on the configuration.

So for example, you could have a resource like layout_main with one XML file for small devices and a different XML file for large devices.

App resources overview | Android Developers

Create alternate layouts | Support different screen sizes | Android Developers

You can arrange fragments on a layout using the Android Studio layout designer.

You can add Fragments and navigate.

First of all yu need a navigation: In the left hand side on Android Studio you can find the Resource Manager Then click to Navigation then click to + and choose the Navigation resource file

After this you can add fragment to the navigation: New Destination (green +) (Don't forget to give name to your fragments).

After this you can add the navigation to your activity's xml. You should use the app:menu=”@menu/bottom_nav_menu” code in your xml

Here a video about the process: https://www.youtube.com/watch?v=Chso6xrJ6aU
