Pass a string from the main fragment activity to fragment activity in viewpager

I want to pass a line to the whole fragment (child) from the activity of the fragment (main), maybe this image can explain what exactly I want to do

https://dl.dropboxusercontent.com/u/57465028/SC20140205-163325.png

therefore, at the top of the picture ... I want to transfer the line from edittext by clicking the button for all actions in the viewpager .... how can I do this?

I tried to execute this code https://stackoverflow.com/a/3129609/2129 , but it could not solve my problem.

Please help me ... I'm stuck

Thanks in advance.

here is my code from fragment activity (MainActivity)

Public class Swipe_Menu extends FragmentActivity {

//String KeyWord;


//private static final String KEYWORD = "keyword";

private ViewPager _mViewPager;
private ViewPagerAdapter _adapter;
/** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.swipe_menu_image);


    Button Back = (Button)findViewById(R.id.account);
    ImageButton Search = (ImageButton)findViewById(R.id.search);
    EditText Keyword = (EditText)findViewById(R.id.keyword);

    final String KeyWord = Keyword.getText().toString(); 


    /**
     * Back button click event
     * */
    Back.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {

            finish();
        }
    });



    setUpView();
    setTab();
}

protected void sendValueToFragments(String value) {
    // it has to be the same name as in the fragment
    Intent intent = new Intent("my_package.action.UI_UPDATE");
    intent.putExtra("UI_KEY", KeyWord  );
    LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
}

and here is my fragment (Child Activity)

public class Store_Swipe extends Fragment {

public static final String ACTION_INTENT = "my_package.action.UI_UPDATE";

String KeyWord;
private TextView kata_keyword;

protected BroadcastReceiver receiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        if(ACTION_INTENT.equals(intent.getAction())) {
            String value = intent.getStringExtra("UI_KEY");
            updateUIOnReceiverValue(value);
        }
    }
};

private void updateUIOnReceiverValue(String value) {
    // you probably want this:
    KeyWord = value;
}

public static Fragment newInstance(Context context) {
    Store_Swipe f = new Store_Swipe();
    return f;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    IntentFilter filter = new IntentFilter(ACTION_INTENT);
    LocalBroadcastManager.getInstance(getActivity()).registerReceiver(receiver, filter);
}

@Override
public void onDestroy() {
    LocalBroadcastManager.getInstance(getActivity()).unregisterReceiver(receiver);
    super.onDestroy();
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    /*Bundle bundle = this.getArguments();
    KeyWord = bundle.getString("keyword");*/
    View view = inflater.inflate(R.layout.store_swipe, container, false);
    init(view);

    return view;

}

void init(View view) {
    kata_keyword = (TextView) view.findViewById(R.id.keyword);
    //ImageView image = (ImageView) view.findViewById(R.id.image_error);
    kata_keyword.setText(KeyWord);
}

}
