Question

您可以告诉我以下代码的错误吗？ logcat在onCreate方法中说明了它。所有这些在mainactivity中都是正确的，因为我已经通过字符串传递了包。

@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();

Answer 1

尝试在onActivityCreated（）{}中设置文本。

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

    CurrentBookingFragmentTV.setText(strtext);    
}

Android Java，从主要活动到碎片问题的getString
