Android Java，getString从主要活动到一个片段问题

Question

嗨，有人能告诉我什么是错误的下面的代码。 logcat在onCreate方法中表示它。所有的主要活动似乎都是正确的，因为我已经通过了字符串包。

@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; 
    } 
} 

这里是日志：

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设置文本（）{}。

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

    CurrentBookingFragmentTV.setText(strtext);  
}
