android - DialogFragment 关闭后重新加载 fragment

Question

我有Index.class作为Activity，当用户选择Profile时，它会调用 fragment Profile

  if (id == R.id.nav_profile){
        FragmentTransaction transaction = getSupportFragmentManager()
                .beginTransaction();
        transaction.setCustomAnimations(R.anim.enter,R.anim.exit,R.anim.enter,R.anim.exit);
        transaction.replace(R.id.flContent, new Profile(), "ProfileFragment");
        transaction.addToBackStack(null);
        viewPager.getAdapter().notifyDataSetChanged();
        transaction.commit();
    }

现在在 Profile Fragment 中，当用户单击按钮时，它将调用 DevRegistration Activity

 case 1:
            btnBeDeveloper.setText("Developer Console");
            btnBeDeveloper.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                     Intent index = new Intent(getActivity(), DevRegistration.class);
                    startActivity(index);
                }
            });
            break;

然后在 DevRegistration 类中，点击注册按钮后，会显示一个对话框 fragment 类。
我想要做的是当我单击对话框 fragment 内的按钮时，如何刷新配置文件 fragment ？

对话框 fragment 类:

public class df_SuccessDevRegistration extends DialogFragment {

Button btnDevGoProfile;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
    View rootView = inflater.inflate(R.layout.fragment_success_developer_registration, container, false);

    btnDevGoProfile = (Button) rootView.findViewById(R.id.btnDevGoProfile);

    btnDevGoProfile.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dismiss();
            getFragmentManager().popBackStack();
            getActivity().finish();

            Profile fragment = (Profile)
                    getSupportFragmentManager().findFragmentByTag("ProfileFragment");

            FragmentTransaction transaction = getSupportFragmentManager().beginTransaction()
            transaction.detach(fragment);
            transaction.attach(fragment);
            transaction.commit();

        }
    });

    return rootView;
}

}

顺便说一句，我不知道为什么 getSupportFragmentManager 不起作用。它显示错误无法解析方法...当我使用 getFragmentManager() 时它崩溃了。

您也可以尝试刷新当前 fragment

 FragmentTransaction ftran = getActivity().getFragmentManager().beginTransaction();
 ftran .detach(this).attach(this).commit();
