I want to pass a list of objects from one activity from another activity. I have one class SharedBooking Below:

public class SharedBooking {
  public int account_id;
  public Double betrag;
  public Double betrag_effected;
  public int taxType;
  public int tax;
  public String postingText;
}

Code from Calling activity:

public List<SharedBooking> SharedBookingList = new ArrayList<SharedBooking>();

public void goDivision(Context context, Double betrag, List<SharedBooking> bookingList) {
  final Intent intent = new Intent(context, Division.class);    
  intent.putExtra(Constants.BETRAG, betrag);        
  intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);  
  context.startActivity(intent);        
}

COde on called activity:

Bundle extras = getIntent().getExtras();
if (extras != null) {
  amount = extras.getDouble(Constants.BETRAG,0);
}

How can I send the list of SharedBooking from one activity and receive that on other activity?

Please suggest me any usable link or sample code.

First, make the class of the list implement Serializable.

public class Object implements Serializable{}

Then you can just cast the list to (Serializable). Like so:

List<Object> list = new ArrayList<Object>();
myIntent.putExtra("LIST", (Serializable) list);

And to retrieve the list you do:

Intent i = getIntent();
list = (List<Object>) i.getSerializableExtra("LIST");

That's it.

Use parcelable. Here is how you will do it:

public class SharedBooking implements Parcelable{

    public int account_id;
    public Double betrag;
    public Double betrag_effected;
    public int taxType;
    public int tax;
    public String postingText;

    public SharedBooking() {
        account_id = 0;
        betrag = 0.0;
        betrag_effected = 0.0;
        taxType = 0;
        tax = 0;
        postingText = "";
    }

    public SharedBooking(Parcel in) {
        account_id = in.readInt();
        betrag = in.readDouble();
        betrag_effected = in.readDouble();
        taxType = in.readInt();
        tax = in.readInt();
        postingText = in.readString();
    }

    public int getAccount_id() {
        return account_id;
    }
    public void setAccount_id(int account_id) {
        this.account_id = account_id;
    }
    public Double getBetrag() {
        return betrag;
    }
    public void setBetrag(Double betrag) {
        this.betrag = betrag;
    }
    public Double getBetrag_effected() {
        return betrag_effected;
    }
    public void setBetrag_effected(Double betrag_effected) {
        this.betrag_effected = betrag_effected;
    }
    public int getTaxType() {
        return taxType;
    }
    public void setTaxType(int taxType) {
        this.taxType = taxType;
    }
    public int getTax() {
        return tax;
    }
    public void setTax(int tax) {
        this.tax = tax;
    }
    public String getPostingText() {
        return postingText;
    }
    public void setPostingText(String postingText) {
        this.postingText = postingText;
    }
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeInt(account_id);
        dest.writeDouble(betrag);
        dest.writeDouble(betrag_effected);
        dest.writeInt(taxType);
        dest.writeInt(tax);
        dest.writeString(postingText);

    }

    public static final Parcelable.Creator<SharedBooking> CREATOR = new Parcelable.Creator<SharedBooking>()
    {
        public SharedBooking createFromParcel(Parcel in)
        {
            return new SharedBooking(in);
        }
        public SharedBooking[] newArray(int size)
        {
            return new SharedBooking[size];
        }
    };

}

Passing the data:

Intent intent = new Intent(getApplicationContext(),YourActivity.class);
Bundle bundle = new Bundle();
bundle.putParcelable("data", sharedBookingObject);
intent.putExtras(bundle);
startActivity(intent);

Retrieving the data:

Bundle bundle = getIntent().getExtras();
sharedBookingObject = bundle.getParcelable("data");

    • Thanks , good answer , i have modified my code but i need to pass list of sharedBooking class , not a single objects , then please explain me how i pass list of object ?
      • 1
    • you can use bundle.putParcelableArrayList(key, value) to set the and bundle.getParcelableArrayList(key) to get the list.

    • @VineetShukla in the line: bundle.putParcelable("data", sharedBookingObject); what is sharedBookingObject ?? one object or a list of objects ?????

Parcelable object class

    public class Student implements Parcelable {

        int id;
        String name;

        public Student(int id, String name) {
            this.id = id;
            this.name = name;

        }

        public int getId() {
            return id;
        }

        public String getName() {
            return name;
        }


        @Override
        public int describeContents() {
            // TODO Auto-generated method stub
            return 0;
        }

        @Override
        public void writeToParcel(Parcel dest, int arg1) {
            // TODO Auto-generated method stub
            dest.writeInt(id);
            dest.writeString(name);
        }

        public Student(Parcel in) {
            id = in.readInt();
            name = in.readString();
        }

        public static final Parcelable.Creator<Student> CREATOR = new Parcelable.Creator<Student>() {
            public Student createFromParcel(Parcel in) {
                return new Student(in);
            }

            public Student[] newArray(int size) {
                return new Student[size];
            }
        };
    }

And the list

ArrayList<Student> arraylist = new ArrayList<Student>();

Code from Calling activity

Intent intent = new Intent(this, SecondActivity.class);
Bundle bundle = new Bundle();
bundle.putParcelableArrayList("mylist", arraylist);
intent.putExtras(bundle);       
this.startActivity(intent);

Code on called activity

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);   

    Bundle bundle = getIntent().getExtras();
    ArrayList<Student> arraylist = bundle.getParcelableArrayList("mylist");
}

You may want to implement the Parcelable Interface in your SharedBooking class and add them to the Intent i.e. with the putParcelableArrayListExtra Method. Check the documentation.

    • i have modified the class :- public class SharedBooking implements Parcelable and implement its unimplement methods , but i send this using intent.putParcelableArrayListExtra(Constants.BOOKING_LIST, bookingList); where bookingList is ArrayList . But how i declare this list in any activity and how i add an object in this activity .

You can also convert the list to a String using Gson, then pass it like so:

String yourListAsString = new Gson().toJson(yourList);
bundle.putString("data",yourListAsString);

Then retrieve it back using your class as the type:

List<YourList> listName = new Gson().fromJson("data", new TypeToken<List<YourList>>(){}.getType());
