Answer 1

I have found simplest way to create Parcelable class

Answer 2

2. Create a class

public class Sample {

Answer 3

It is very easy, you can use a plugin on android studio to make objects Parcelables.

public class Persona implements Parcelable {
String nombre;
int edad;
Date fechaNacimiento;

public Persona(String nombre, int edad, Date fechaNacimiento) {
    this.nombre = nombre;
    this.edad = edad;
    this.fechaNacimiento = fechaNacimiento;
}

@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeString(this.nombre);
    dest.writeInt(this.edad);
    dest.writeLong(fechaNacimiento != null ? fechaNacimiento.getTime() : -1);
}

protected Persona(Parcel in) {
    this.nombre = in.readString();
    this.edad = in.readInt();
    long tmpFechaNacimiento = in.readLong();
    this.fechaNacimiento = tmpFechaNacimiento == -1 ? null : new Date(tmpFechaNacimiento);
}

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

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

Answer 4

To put: bundle.putSerializable("key",(Serializable) object);

To get: List<Object> obj = (List<Object>)((Serializable)bundle.getSerializable("key"));

Answer 5

Now you can use Parceler library to convert your any custom class in parcelable. Just annotate your POJO class with @Parcel. e.g.

    @Parcel
    public class Example {
    String name;
    int id;

    public Example() {}

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

    public String getName() { return name; }

    public int getId() { return id; }
}

you can create an object of Example class and wrap through Parcels and send as a bundle through intent. e.g

Bundle bundle = new Bundle();
bundle.putParcelable("example", Parcels.wrap(example));

Now to get Custom Class object just use

Example example = Parcels.unwrap(getIntent().getParcelableExtra("example"));
