Apps Layout Inflater or different Fragments

[wakille]

Hey,
I am programming a TabLayout and not sure what the best way is to change the content, when changing the tab. Should I use Fragments or just inflate a new Layout, everytime I change the tab. Could you maybe give some pro and con for both methods ?

Thanks!

You're misunderstanding something here. Use Fragments for a Tablayout, and you must also inflate the Fragment layout.
Have a look at some tutorial examples, like this

Based on this project, is there a way to pass data between fragment using viewmodel and .observe()?
Exemple one fragment contains a buton which increment a value in viewmodel and the observer of the 2nd and 3rd fragment update their textview with this value?
I am stuck on the fact that the .observe do not react to the value change....
