我想将某些列表从片段传递到另外2个片段中。当我将数据传递给第二个片段时,它进展顺利。但是当传递给片段三时是错误的

错误代码

OneFragment.java中的密码

Bundle bundle=new Bundle();
                    bundle.putStringArrayList("keys", keys);
                    //set Fragmentclass Arguments
                    Fragment fragobj=new TwoFragment();
                    fragobj.setArguments(bundle);
                    FragmentManager fragmentManager = getFragmentManager();
                    fragmentManager.beginTransaction().replace(R.id.frag2, fragobj).commitAllowingStateLoss();

                    Bundle bundle2=new Bundle();
                    bundle2.putStringArrayList("keys", keys);
                    //set Fragmentclass Arguments
                    Fragment fragobj2=new ThreeFragment();
                    fragobj2.setArguments(bundle2);
                    FragmentManager fragmentManager2 = getFragmentManager();
                    fragmentManager2.beginTransaction().replace(R.id.fragment3, fragobj2).commitAllowingStateLoss();

TwoFragment的第一通表现不错。但是第二遍给了我这样的错误。请帮我。我已经检查过ThreeFragment.xml中的所有ID并全部正确。

ThreeFragment.java

package com.example.yehezkiel.eclassapp;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import java.util.ArrayList;
import java.util.List;


public class ThreeFragment extends Fragment {
    View v;
    private List<DaftarPengumuman> listPengumuman = new ArrayList<>();
    private ArrayList<String> obj3 = new ArrayList<>();

    public ThreeFragment() {
        // Required empty public constructor
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

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

        v =  inflater.inflate(R.layout.fragment_three, container, false);

        Bundle bundle = this.getArguments();
        if(getArguments()!=null)
        {
            obj3 = bundle.getStringArrayList("keys");
            Log.e("nba",obj3.toString());
        }



        // Inflate the layout for this fragment
        return v;
    }
}

fragment_three.xml
