Залп нулевой запрос

Question

Я пытаюсь сменить пароль в приведенном ниже фрагменте.Но когда я ввожу значения, никаких действий не происходит.У меня есть 3 поля:
1. current_password
2. new_password
3. re-enter_password.

Я использую залп.Я тестировал на отладчике значения равны нулю.Только условие if, где curr_pass.equals("")... работает.как мне поступить?Ниже приведен весь фрагмент с инициализированными представлениями.

public class Change_password extends Fragment {
EditText current_pass,new_pass,re_enter_pass;
String curr_pass, newer_pass, re_pass,id;
Button changePwd_btn;
AlertDialog.Builder builder;
Session session;
String SP = "Name";
String url = "https://vendorapp.web4rest.com/VendorController/changePassword";
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    //returning our layout file
    //change R.layout.yourlayoutfilename for each of your fragments
    View v = inflater.inflate(R.layout.change_password, container, false);

    builder = new AlertDialog.Builder(getContext());
    current_pass = v.findViewById(R.id.current_pwd);
    new_pass = v.findViewById(R.id.new_pwd);
    re_enter_pass = v.findViewById(R.id.re_enter_pwd);
    changePwd_btn = v.findViewById(R.id.change_pwd);
    changePass();
    return v;
}

  changePwd_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            ConnectivityManager ConnectionManager = (ConnectivityManager)getActivity().getSystemService(Context.CONNECTIVITY_SERVICE);
            NetworkInfo networkInfo = ConnectionManager.getActiveNetworkInfo();
            if (networkInfo != null && networkInfo.isConnected() == true) {
                curr_pass = current_pass.getText().toString();
                newer_pass = new_pass.getText().toString();
                re_pass = re_enter_pass.getText().toString();

                if (curr_pass.equals("") || newer_pass.equals("") || re_pass.equals("")) {
                    builder.setTitle("Something went wrong!!");
                    displayAlert("Enter valid details");
                }else{
