Help required: How to collect the data of all stepper fragments in last fragment to push on server?

[GuillaumeEbert]

I use the ViewModel component. (doc https://developer.android.com/topic/libraries/architecture/viewmodel.html

Put all your data object in the viewHolder In each fragement register the ViewModel to the parent activity like this ViewModelProviders.of(getActivity()).get(ClassOfTheViewHolder.class);

On the on select method get your data from the viewHolder from a getter and Voila your data can be shared between fragments. Just remind you that the ViewHolder is link to the activity life cycle.

Good codding
