Remarks

Interface for classes whose instances can be written to and restored from a Parcel. Classes implementing the Parcelable interface must also have a non-null public static field called CREATOR of a type that implements the Parcelable.Creator interface.

A typical implementation of Parcelable is:

<div> <div class="ds-selector-tabs"><section><h3 id="kotlin">Kotlin</h3>

class MyParcelable private constructor(`in`: Parcel) : Parcelable {
                private val mData: Int = `in`.readInt()

                override fun describeContents(): Int {
                    return 0
                }

                override fun writeToParcel(out: Parcel, flags: Int) {
                    out.writeInt(mData)
                }

                companion object CREATOR: Parcelable.Creator&lt;MyParcelable?&gt; {
                    override fun createFromParcel(`in`: Parcel): MyParcelable? {
                        return MyParcelable(`in`)
                    }

                    override fun newArray(size: Int): Array&lt;MyParcelable?&gt; {
                        return arrayOfNulls(size)
                    }
                }
            }

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&lt;MyParcelable&gt; CREATOR
                        = new Parcelable.Creator&lt;MyParcelable&gt;() {
                    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();
                }

Fields

ContentsFileDescriptor

Descriptor bit used with #describeContents(): indicates that the Parcelable object's flattened representation includes a file descriptor.

Properties

Handle	Gets the JNI value of the underlying Android object. (Inherited from IJavaObject)
JniIdentityHashCode	Returns the value of `java.lang.System.identityHashCode()` for the wrapped instance. (Inherited from IJavaPeerable)
JniManagedPeerState	State of the managed peer. (Inherited from IJavaPeerable)
JniPeerMembers	Member access and invocation support. (Inherited from IJavaPeerable)
PeerReference	Returns a JniObjectReference of the wrapped Java object instance. (Inherited from IJavaPeerable)

Methods

DescribeContents()	Describe the kinds of special objects contained in this Parcelable instance's marshaled representation.
Disposed()	Called when the instance has been disposed. (Inherited from IJavaPeerable)
DisposeUnlessReferenced()	If there are no outstanding references to this instance, then calls `Dispose()`; otherwise, does nothing. (Inherited from IJavaPeerable)
Finalized()	Called when the instance has been finalized. (Inherited from IJavaPeerable)
SetJniIdentityHashCode(Int32)	Set the value returned by `JniIdentityHashCode`. (Inherited from IJavaPeerable)
SetJniManagedPeerState(JniManagedPeerStates)	(Inherited from IJavaPeerable)
SetPeerReference(JniObjectReference)	Set the value returned by `PeerReference`. (Inherited from IJavaPeerable)
UnregisterFromRuntime()	Unregister this instance so that the runtime will not return it from future Java.Interop.JniRuntime+JniValueManager.PeekValue invocations. (Inherited from IJavaPeerable)
WriteToParcel(Parcel, ParcelableWriteFlags)	Flatten this object in to a Parcel.

Extension Methods

JavaCast<TResult>(IJavaObject)	Performs an Android runtime-checked type conversion.
JavaCast<TResult>(IJavaObject)
GetJniTypeName(IJavaPeerable)
