将微调器选定的项目从第1个片段传递到第2个片段

Question

我在FragmentOne.class中有2个微调器从stackoverflow中搜索了很多，没有人回答我的情况

• fromcountryspinner
• tocountryspinner

从微调器中选择项目时，它们应显示在Textviews

中的FragmentTwo.class中

用于FragmnetOne.class：

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

            Bundle bundle = new Bundle();
            bundle.putString("countryfrom", fromcountryspinner.getSelectedItem().toString());

            bundle.putString("countryto", tocountryspinner.getSelectedItem().toString());

            FragmentTwo fragment = new FragmentTwo();
            fragment.setArguments(bundle);            


`getFragmentManager().beginTransaction().replace(R.id.container_fragment, fragment).commit();

            }
        });

获取该值的FragmentTwo.class中的

：

 @Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View view = inflater.inflate(R.layout.fragment_order_car_page, container, false);
TextView txtfromcountry = (TextView) view.findViewById(R.id.txt_fromcountry);
 TextView txttocountry = (TextView) view.findViewById(R.id.txt_tocountry);

    String countryfrom = this.getArguments().getString("countryfrom");
    txtfromcountry.setText(countryfrom);
    String countryto = this.getArguments().getString("countryto");
    txttocountry.setText(countryto);
return view;
}

该应用程序崩溃。当在崩溃日志中点击时，它指向类 FragmentTwo.clas 任何想法是什么错误？

Logcat：我更改了片段类的名称，以便理解：OrderCarPage是FragmentTwo.class
