Android - How to pass data between fragments

Question

I am trying to pass a data from a clickable TextView to EditText between the fragments. Right now I am able to navigate to the other fragment when clicking the TextView. This is the coding of CategoryFragment:

public boolean onChildClick(ExpandableListView parent, View v,
                                        int groupPosition, int childPosition, long id) {
                // TODO Auto-generated method stub
                Toast.makeText(
                        getActivity().getApplicationContext(),
                        listDataHeader.get(groupPosition)
                                + " : "
                                + listDataChild.get(
                                listDataHeader.get(groupPosition)).get(
                                childPosition), Toast.LENGTH_SHORT)
                        .show();
                FragmentManager fragmentManager = getFragmentManager();
                FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

                HomeFragment fragment = new HomeFragment();
                fragmentTransaction.replace(R.id.frame_container, fragment);
                fragmentTransaction.commit();
                return false;
            }

I feel that this can be done because the toast is able to retrieve the string inside the listDataChild. What I can't seem to solve overnight is that how to retrieve the listDataChild strings and pass it, from Fragment 1 to Fragment 2, where Fragment 2 contains one EditText box. How can I put the string from textview to edittext?

Answer 1

You can pass data between fragments using bundle...

Bundle args = new Bundle();

HomeFragment fragment = new HomeFragment();

args.putInt("key", value);

fragment .setArguments(args);

Answer 2

In CategoryFragment pass data using Bundle like

HomeFragment fragment = new HomeFragment();
Bundle bundle = new Bundle();
bundle.putString("key", listDataChild.get(
                                listDataHeader.get(groupPosition)).get(
                                childPosition));
fragment.setArguments(bundle);

In HomeFragment use this code in onActivityCreated(....)

Bundle bumdle = getArguments();
if (bundle  != null)
 String value = bundle.getString("key");
