Pass arrayList from one fragment to another

I want to pass an Arraylist (SearchModl is a class) from one fragment to another. i am using Bundle to do this.But when ever I get the bundle in other fragment,i am getting null value

SearchModel

public class SearchModel implements Serializable {

    private String code,category, minExp, maxExp, postedOn, counts, applied, position, desc, type, hour, status, expiryDate, address, gender, religion, summary, requestId, requestorId;

    public SearchModel(String code,String category, String minExp, String maxExp, String postedOn, String counts, String applied, String position, String desc, String type, String hour, String status, String expiryDate, String address, String gender, String religion, String summary, String requestId, String requestorId) {
        this.code=code;
        this.category = category;
        this.minExp = minExp;
        this.maxExp = maxExp;
        this.postedOn = postedOn;
        this.counts = counts;
        this.applied = applied;
        this.position = position;
        this.desc = desc;
        this.type = type;
        this.hour = hour;
        this.status = status;
        this.expiryDate = expiryDate;
        this.address = address;
        this.gender = gender;
        this.religion = religion;
        this.summary=summary;
        this.requestId = requestId;
        this.requestorId = requestorId;
    }

Fragment A

for (int i = 0; i < tableArray.length(); i++) {
                                        JSONObject table = tableArray.getJSONObject(i);
                                        data = new SearchModel(table.getString("Job_Code"), table.getString("Job_Category"), table.getString("Min_Exp"), table.getString("Max_Exp"), table.getString("Posted_On"), table.getString("Candidate_Counts"), table.getString("Applications"), table.getString("No_Of_Pos"), table.getString("Job_Desc"), table.getString("Job_Type"), table.getString("Job_Hours"), table.getString("Job_Status"), table.getString("Job_Exp_Date"), table.getString("Address"), table.getString("Gender_Name"), table.getString("Religion_Name"), table.getString("Exp_Summary"), table.getString("IJob_Request_ID"), table.getString("Requestor_Name"));
                                        values.add(data);

                                    }

//                                    getArrayList.getArray(values);


                                    bundle.putSerializable("array", (java.io.Serializable) values);

                                }
                            } catch (JSONException e1) {
                                e1.printStackTrace();
                            }
                        }
                        CommonFunctions.showProgress(getActivity(), "Please Wait...", false);
                        fragmentTransaction = getFragmentManager().beginTransaction();
                        SearchJobList searchJobList = new SearchJobList();
                        searchJobList.setArguments(bundle);
                        fragmentTransaction.replace(R.id.header_container, searchJobList, "searchJob").commit();
                    }
                });

Second Fragment

public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        data = new ArrayList<SearchModel>();
        Bundle bundle = getArguments();
        data = (List<SearchModel>) bundle.getSerializable("array");
        getArrayList = new GetArrayList() {
            @Override
            public void getArray(List<SearchModel> listValues) {
                data = listValues;
                jobAdapter = new SearchJobAdapter(getActivity(), data);
                setListAdapter(jobAdapter);
            }
        };

    }

1.Implement a singleton class as the example to pass object. (Hopefully you know what's singleton, I you don't, add comment to tell me.

class ExampleClass {
    private ExampleClass () {}

    static ExampleClass obj = nil;
    public ExampleClass instance() {
         if (obj == nil) obj = new ExampleClass ();
         return obj;
    }

    public ArrayList<SearchModel> cache;
 }

2.In the from activity,

ExampleClass .instance().cache = Cus_Obje_arraylist;

3.Then in the to activity, you can get it from the bridge class.

ArrayList<SearchModel> Cus_Obje_arraylist = ExampleClass.instance().cache;

You can simply keep the ArrayList in your Activity where it is available to both Fragments.

Dynamically, you create a public method in your fragment and after you create the fragment, you pass the List via a setter. 

 YourActivity extends Activity {

   void createFragment(){
        YourFragment yourFragment = Fragment.getInstance();
        yourFragment.setList(models);
  }

}

YourFragment extends Fragment {
  private List<SearchModel> models; 

  public void setList(List<SearchModel> models){
        models = models;
  }
}

Statically, not the best solution either:

YourActivity extends Activity {
    static ArrayList<SearchModel> models;


}

YourFragment extends Fragment {

  public void doSomething(){
        List<SearchModel> model = YourActivity.models;
  }
}

Implementing PArcelable would be the best solution though:

http://developer.android.com/reference/android/os/Parcelable.html There is a solution right here: Android ArrayList<MyObject> pass as parcelable
