Problem in implementing Parcelable containing other Parcelable

Question

I\'m implementing Parcelable class that has another Parcelable insde.

In OuterParcelable class:

@Override
public void writeToParcel(Parcel dest, int          


        

Answer 1

Why are you putting the value into a Bundle? Did you completely implement the parcelable in your class?

Parcelable Skeleton

public MyClass(Parcel in) {
    readFromParcel(in);
}

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

@Override
public void writeToParcel(Parcel dest, int flags) { 
    dest.writeParcelable(aParcelableClass, flags);
}

private void writeObject(Parcel dest, Object obj) {
    if (obj != null) {
        dest.writeInt(1);
        dest.writeValue(obj);
    } else {
        dest.writeInt(0);
    }
}

public void readFromParcel(Parcel in) {
    aParcelableClass = in.readParcelable(ParcelableClass.class.getClassLoader());
}

private Object readObject(Parcel in) {
    Object value = null;

    if (in.readInt() == 1) {
        value = in.readValue(null); // default classloader
    }

    return value;
}

public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
    @Override
    public MyClass createFromParcel(Parcel source) {
        return new MyClass(source);
    }

    @Override
    public MyClass[] newArray(int size) {
        return new MyClass[size];
    }
};

I added a few things to make null values more easily dealt with, but the principle is the same. You need the @Override items, constructor, and Creator.

If you're going to read and write a parcelable you will have issues if you specify null as the class loader.
