Android weird behaviour

public class DayOfWeek extends Fragment
{
    private View rootView;
    private Switch toggle;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        rootView = inflater.inflate(R.layout.fragment_dayofweek, container, false);

        toggle = (Switch) rootView.findViewById(R.id.hint_switch);
        toggle.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener()
        {
            @Override
            public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked)
            {
                process();
            }
        });

        rootView.findViewById(R.id.button).setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View view)
            {
                process();
            }
        });

        return rootView;
    }

    private void process()
    {
        String day = ((EditText) rootView.findViewById(R.id.day)).getText().toString();
        String month = ((EditText) rootView.findViewById(R.id.month)).getText().toString();
        String year = ((EditText) rootView.findViewById(R.id.year)).getText().toString();

        if (!(Validator.isInteger(day) && Validator.isInteger(month) && Validator.isInteger(year))) {
            displayWarning();
            return;
        }

        if (ba.isDateValid()) {

            TextView tv = (TextView) rootView.findViewById(R.id.textView);
            tv.setText(result);
            tv.setTextAlignment((toggle.isChecked() ? View.TEXT_ALIGNMENT_TEXT_START : View.TEXT_ALIGNMENT_CENTER));
