Question

I have an activity with three fragments in it, This is how I communicate between the three fragments:

First I display only FragmentA in ActivityA<

Answer 1

In such circumstances in which multiple fragments and activities want to communicate with each other, two options come in mind.

• Java Interfaces - Only one activity and one or more fragments. Each fragment should implement its own interface. Activity is also used for a shared channel among them. Recommended

• Local broadcasts - Can be used among multiple activities and services. This also can be used for communicating between fragments.
