Fragment "refresh" Android

I'm trying to build an Android and I have a fragment Fragment_X in which I read the response from the server (data of the user who logged in) and then create a table.

The fragment isn't the first to show up when the activity starts.

After the login if I select the Fragment_X the table doesn't show up, I have to click on it another time and finally the table appears.

Is there a way to make it appear at the first time I select the Fragment_X?

Here is my code:

Fragment_X

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.fragment_ordini, container, false);

    connection = new DBConnection(c.getId(), getContext());
    connection.downloadOrdiniUtente();
    CookieO cookieO = new CookieO();
    File ordini = new File(path);
    if (ordini.exists()) {
        createTable(cookieO.getOrdini(), v);
    }


    return v;
}

You should wait at least for 500ms when fragment created. After onCreateVeiw wait for 500ms and then make a table. for example

onCreateView() {
View view = ............

ProgressDialog dialog = new ProgressDialog(getActivity);
dialog.setMessage("Wait Please");
dialog.show();

new Timer().schedule(new TimerTask() {
            @Override
            public void run() {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // here u can display your table
                         showTable();
                         dialog.dismiss();
                    }
                });
            }
        },500);

return view;
}
