Send data to fragment using FragmentTransaction

I am in my fragment class calling this:

@OnClick(R.id.blockedLinkLayout)
public void onBlockedClick(){
    final FragmentTransaction ft = getFragmentManager().beginTransaction();
    ft.replace(R.id.content, new SettingsBlockedUsersFragment(), FRAGMENT_TAG);
    ft.commit();
}

And it will just replace my current fragment with the selected one.

And my question is: how can I send some data (e.g. String) from my parent fragment to my child fragment using FragmentTransaction?

Just pass them in a bunch as fragmented arguments

in parent fragment:

SettingsBlockedUsersFragment fragment = new SettingsBlockedUsersFragment();
Bundle arguments = new Bundle();
arguments.putString( string_key , desired_string);
fragment.setArguments(arguments);
final FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.content, fragment , FRAGMENT_TAG);
ft.commit();

in child fragment:

Bundle arguments = getArguments();
String desired_string = arguments.getString(string_key);

FragmentTransaction- this is just a transition of Fragments, it does not miss anything. You need to use Bundle.

SettingsBlockedUsersFragment frag = new SettingsBlockedUsersFragment();
Bundle b = new Bundle();
// put stuff into bundle...
b.putString("user", "steve");

// Pass the bundle to the Fragment
frag.setArguments(b);

// Use Fragment Transaction
final FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.content, frag, FRAGMENT_TAG);
ft.commit();

Then inside the inline fragment you can do

String user = getArguments().getString("user");

factory ( )

public static YourFragment newInstance(String sample) {
    YourFragment fragment = new YourFragment();
    Bundle args = new Bundle();
    args.putString(KEY, sample);
    fragment.setArguments(args);
    return fragment;

YourFragment.newInstance(, ); .

setArguments() . oncreate, ,

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (getArguments() != null) {
        streamSource = getArguments().getParcelable(KEY);
    }

SettingsBlockedUsersFragment ,

public class SettingsBlockedUsersFragment extends Fragment {
    private static final String MY_STRING = "my_string";


    public static SettingsBlockedUsersFragment newInstance(String yourStringValue){
        SettingsBlockedUsersFragment frag = new SettingsBlockedUsersFragment();
        Bundle args = new Bundle();
        args.putString(MY_STRING, yourStringValue);
        frag.setArguments(args);
        return frag;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState){
          Bundle args = getArguments();
          if(args != null){
               String myString = args.getString(MY_STRING);
          }
    }
}


final FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.replace(R.id.content,SettingsBlockedUsersFragment.newInstance("my string"), FRAGMENT_TAG);
ft.commit();
