how to transfer extra data from one fragment to another through activity

Question

For example, In a list view hosted by ListActivity, when user click on a item on the list, a new activity will be launched, and previous activity transfer extra data to the new activity like below:

public class Notepadv2 extends ListActivity {
    ...

   @Override
    protected void onListItemClick(ListView l, View v, int position, long id) {
        super.onListItemClick(l, v, position, id);

        Intent i = new Intent(this, NoteEdit.class);
        i.putExtra(NotesDbAdapter.KEY_ROWID, id);
        startActivityForResult(i, ACTIVITY_EDIT);
     }
}

How it should be If I use fragments? I mean if I have one Activity which host 2 fragments, and make fragments transactions like below:

// Create new fragment and transaction
Fragment newFragment = new ExampleFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();

// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);

// Commit the transaction
transaction.commit();

how can I transfer extra data from one fragment to the other fragment through the host activity?

I know on android developer webpage, there is a good document of how to use fragment and how to communicate with activity, but there is no description about how to transfer data from one fragment to another....

Use

Bundle data = new Bundle();
data.putString("name",value);
Fragment fragment = new nameOfFragment();
fragment.setArguments(data);
.navigateTo(fragment);

Do you mean I do not need to define interface in fragment and let the host activity to implement the interface which set up a communication between fragment and host acvitity... instead, I can use your code to directly navigate to the next fragment? – Leem.fin Feb 03 '12 at 12:03

From Activity you send data with intent as:

Bundle bundle = new Bundle();
bundle.putString("key", "value");
// set Fragmentclass Arguments
Fragmentclass fragmentobj = new Fragmentclass();
fragmentobj.setArguments(bundle);

and in Fragment onCreateView method:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    String strtext = getArguments().getString("key");    
    return inflater.inflate(R.layout.fragment, container, false);
}

I hope it is help full to you.
