How can I make my custom objects Parcelable?

I'm trying to make my objects Parcelable. However, I have custom objects and those objects have

attributes of other custom objects I have made.

What would be the best way to do this?


You can find some examples of this here, here (code is taken here), and here.

You can create a POJO class for this, but you need to add some extra code to make it Parcelable. Have a look at the implementation.

public class Student implements Parcelable{
        private String id;
        private String name;
        private String grade;

        // Constructor
        public Student(String id, String name, String grade){
   = id;
   = name;
            this.grade = grade;
       // Getter and setter methods

       // Parcelling part
       public Student(Parcel in){
           String[] data = new String[3];

  = data[0];
  = data[1];
           this.grade = data[2];

       public int describeContents(){
           return 0;

       public void writeToParcel(Parcel dest, int flags) {
           dest.writeStringArray(new String[] {,
       public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
           public Student createFromParcel(Parcel in) {
               return new Student(in); 

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

Once you have created this class, you can easily pass objects of this class through the Intent like this, and recover this object in the target activity.

intent.putExtra("student", new Student("1","Mike","6"));

Here, the student is the key which you would require to unparcel the data from the bundle.

Bundle data = getIntent().getExtras();
Student student = (Student) data.getParcelable("student");

This example shows only String types. But, you can parcel any kind of data you want. Try it out.

EDIT: Another example, suggested by Rukmal Dias.
