Answer 1

Communication between fragments and the activity they are attached to is explained here. From the fragment to the activity you simply use getActivity for a reference to the activity. From the activity to the fragment you can use the findFragmentById(R.id.fragment_id) method of the FragmentManager for a reference to the fragment you want to communicate with.

Communication between activities is realized through Intent s and their Extras as described here. You basically put your Data in a Bundle and insert it in the Ìntent with putExtras().

In your case you should first have the fragment communicate with its activity and then start a new activity with a Bundle from here.

Answer 2

You should use LocalBroadcastManager To commuicate between two Activities The concept is simple and can be implemented easily check below link

Answer 3

I suggest you to use EventBus for communicating between fragments and activities https://github.com/greenrobot/EventBus
