Communicating between fragment and activity

The easiest way to communicate between your activity and fragments is using interfaces or parameters.

There are different ways to communicate:

*From activity to Fragment:

1. When it is instantiated, We can pass a parameter (Send data from activity to fragment in android)
2. When it was instantiated, We can call a fragment’s method from activity.(Send data from activity to fragment on android II)
3. When we use a TabBar with some fragments, We use a interface in our Adapter.(Communicating activity with fragments in TabBar)

*From fragment to activity:

1. When we need to communicate with activity from fragment, we use a interface. The idea is basically to define an interface a given fragment with onAttach(Activity activity) and onDetach(), and let the activity implement that interface.(Listener from fragment to activity)
