Android Java，getString从主活动到片段问题

嗨，有人能告诉我以下代码有什么问题吗。logcat在onCreate方法中表示它的属性。mainactivity中的所有内容似乎都是正确的，因为我已经用字符串传递了bundle

@SuppressLint("NewApi")
public class CurrentBookingFragment extends Fragment {

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

    View view =inflater.inflate(R.layout.current_booking_fragment, container, false);

    Bundle bundle = this.getArguments();

    String strtext = this.getArguments().getString("GetStringPUFirstLine");

    TextView CurrentBookingFragmentTV = (TextView)view.findViewById(R.id.CurrentBookingFragmentTV);

    CurrentBookingFragmentTV.setText(strtext);

    return view;
    }
 }

以下是日志：

创建片段：

     Fragment CurrentBookingFragment;
     CurrentBookingFragment = new CurrentBookingFragment();
     FragmentManager fm = getFragmentManager();

     Bundle bundle=new Bundle();
     bundle.putString("GetStringPUFirstLine", "GetStringPUFirstLine");

     CurrentBookingFragment.setArguments(bundle);

     FragmentTransaction fragmentTransaction = fm.beginTransaction();
     fragmentTransaction.replace(R.id.BookingFragment, CurrentBookingFragment);
     fragmentTransaction.commit();

尝试在onActivityCreated（）{}中设置文本

如果你的应用程序正在崩溃，如果你的包为空，则从logcatCheck发布堆栈跟踪。并检查在显示fragment.bundle不为null时是否使用setArguments（），iam是否使用setArguments。我会把这封信寄出去log@joao2fast4u-关于bundle为null的确切含义是什么？@user3247335创建片段时，是否在bundle中发送GetStringPUFirstLine的值，以便可以在onCreatView中读取该值？如果没有，则在尝试读取时该值为null，因为没有此类值。我无法在当前方法中设置此方法。（文本视图）旁边的“视图”到底是用来做什么的？

@Override
public void onActivityCreated(Bundle savedInstanceState) 
{
    TextView CurrentBookingFragmentTV = (TextView)view.findViewById(R.id.CurrentBookingFragmentTV);

    CurrentBookingFragmentTV.setText(strtext);    
}
