XML : Changing EditText to default string

hello guys seriously am new to android and please i would like you to help me with this code...to edit it

   public class LoginFragment extends Fragment implements OnClickListener {  private EditText login, password, domain;  private ImageView apply;    @Override  public View onCreateView(LayoutInflater inflater, ViewGroup container,          Bundle savedInstanceState) {      View view = inflater.inflate(R.layout.setup_generic_login, container, false);        login = (EditText) view.findViewById(R.id.setup_username);      password = (EditText) view.findViewById(R.id.setup_password);      domain = (EditText) view.findViewById(R.id.setup_domain);      apply = (ImageView) view.findViewById(R.id.setup_apply);      apply.setOnClickListener(this);        return view;  }    @Override  public void onClick(View v) {      int id = v.getId();        if (id == R.id.setup_apply) {          if (login.getText() == null || login.length() == 0 || password.getText() == null || password.length() == 0 || domain.getText() == null || domain.length() == 0) {              Toast.makeText(getActivity(), getString(R.string.first_launch_no_login_password), Toast.LENGTH_LONG).show();              return;          }            SetupActivity.instance().genericLogIn(login.getText().toString(), password.getText().toString(), domain.getText().toString());      }  }}
