Class Overview

Interface for classes whose instances can be written to and restored from a Parcel. Classes implementing the Parcelable interface must also have a static field called CREATOR, which is an object implementing the Parcelable.Creator interface.

A typical implementation of Parcelable is:

 public class MyParcelable implements Parcelable {
     private int mData;

     public int describeContents() {
         return 0;
     }

     public void writeToParcel(Parcel out, int flags) {
         out.writeInt(mData);
     }

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

         public MyParcelable[] newArray(int size) {
             return new MyParcelable[size];
         }
     };
     
     private MyParcelable(Parcel in) {
         mData = in.readInt();
     }
 }

Summary

Nested Classes
interface	Parcelable.Creator<T>	Interface that must be implemented and provided as a public CREATOR field that generates instances of your Parcelable class from a Parcel.

Constants
int	CONTENTS_FILE_DESCRIPTOR	Bit masks for use with `describeContents()`: each bit represents a kind of object considered to have potential special significance when marshalled.
int	PARCELABLE_WRITE_RETURN_VALUE	Flag for use with `writeToParcel(Parcel, int)`: the object being written is a return value, that is the result of a function such as "`Parcelable someFunction()`", "`void someFunction(out Parcelable)`", or "`void someFunction(inout Parcelable)`".

Public Methods
abstract int	describeContents() Describe the kinds of special objects contained in this Parcelable's marshalled representation.
abstract void	writeToParcel(Parcel dest, int flags) Flatten this object in to a Parcel.

Constants

public static final int CONTENTS_FILE_DESCRIPTOR

Since: API Level 1

Bit masks for use with describeContents(): each bit represents a kind of object considered to have potential special significance when marshalled.

Constant Value: 1 (0x00000001)

public static final int PARCELABLE_WRITE_RETURN_VALUE

Since: API Level 1

Flag for use with writeToParcel(Parcel, int): the object being written is a return value, that is the result of a function such as "Parcelable someFunction()", "void someFunction(out Parcelable)", or "void someFunction(inout Parcelable)". Some implementations may want to release resources at this point.

Constant Value: 1 (0x00000001)

Public Methods

public abstract int describeContents ()

Since: API Level 1

Describe the kinds of special objects contained in this Parcelable's marshalled representation.

Returns

a bitmask indicating the set of special object types marshalled by the Parcelable.

public abstract void writeToParcel (Parcel dest, int flags)

Since: API Level 1

Flatten this object in to a Parcel.

Parameters

dest	The Parcel in which the object should be written.
flags	Additional flags about how the object should be written. May be 0 or `PARCELABLE_WRITE_RETURN_VALUE`.
