To allow a Fragment to communicate up to its Activity, you can define an interface in the Fragment class and implement it within the Activity.
How is fragment to fragment communication done in flow?
Since fragments should be modular, reusable components, the communication happens over an interface that the underlying activity implements. This way we can send data from a fragment to an activity and from there to another fragment either by calling a public method or by instantiating a new fragment and sending the values as arguments to it.
When to use the callback interface in fragment?
For example, the following method in the fragment is called when the user clicks on a list item. The fragment uses the callback interface to deliver the event to the parent activity. In order to receive event callbacks from the fragment, the activity that hosts it must implement the interface defined in the fragment class.
