Populating a listview in a different fragment

Question

I have this code, which gets data from various EditTexts and adds this info into a ListView_item in fragment 1. This ListView_item is supposed to be populated in the ListView in fragment 2. I was thinking this might be possible with the help of the EventBus library but I have not quite yet gotten my head around how.

Here is my populate list method

public void populateList() {
    ArrayAdapter<Appointment> adapter = new AppointmentListAdapter();
    (The listview in fragment 2).setAdapter(adapter);
}

pass your data between two fragments http://stackoverflow.com/questions/27484245/pass-data-between-two-fragments-without-using-activity — karan, Aug 11 '15 at 10:32
The simplest way to do so is make a custom adapter and use it. — Rahul Patidar, Aug 11 '15 at 11:15

You have two ways to do this :

1) Using Interface: You will find lots of links for how to use interface for data passing.

2) Pass adapter through the activity :

step 1 : In your Fragment1 Make getParent() method :

private MyActivity getParent() {
        return ((MyActivity) getActivity());
}

step 2 : In MyActivity Make populateList() method :

public void populateList(ArrayAdapter<Appointment> adapter){
        SecondFragment mSecondFragment = (SecondFragment) getFragmentManager().findFragmentByTag(SecondFragment.TAG);
        mSecondFragment.setAdapter(adapter);
}

step 3 : In your Fragment1 populateList method look like below :

public void populateList() {
        ArrayAdapter<Appointment> adapter = new AppointmentListAdapter();
        getParent().populateList(adapter);
}
