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<MyParcelable?> {
override fun createFromParcel(`in`: Parcel): MyParcelable? {
return MyParcelable(`in`)
}
override fun newArray(size: Int): Array<MyParcelable?> {
return arrayOfNulls(size)
}
}
}
</section><section><h3 id="java">Java</h3>
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();
}
}

Fields
| ContentsFileDescriptor |
Descriptor bit used with |
Properties
| Handle |
Gets the JNI value of the underlying Android object. (Inherited from IJavaObject) |
| JniIdentityHashCode |
Returns the value of |
| 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 |
| Finalized() |
Called when the instance has been finalized. (Inherited from IJavaPeerable) |

| SetPeerReference(JniObjectReference) |
Set the value returned by |
| 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. |
