Android Android Lists and Adapters (2015) Using Parcelable Data Reading Parcelable Data

i am stuck on this

Finally, we need to update the length of the array returned in the Creator's 'newArray()' method. Use the size parameter passed in.

VideoGame.java
public class VideoGame implements Parcelable {

    public String mTitle = "";
    public int mYear = 0;

    public VideoGame() {
        // intentionally blank
    }

    // getters and setters omitted for brevity!

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

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeString(mTitle);
        dest.writeInt(mYear);
    }

    public VideoGame(Parcel in) {
       mTitle = in.readString();
      mYear = in.readInt();
    }

    public static final Creator<VideoGame> CREATOR = new Creator<VideoGame>() {
        @Override
        public VideoGame createFromParcel(Parcel source) {
            return new VideoGame(source);
        }

        @Override
        public VideoGame[] newArray(int size) {
             VideoGame videoGame = new VideoGame[size];
            return new VideoGame[0];
        }
    };
}

Hey Rodrick!

Rather than returning a VideoGame array of the size 0, we want to return a VideoGame array of the size passed in.

In this example, an int size is passed in - see if you can figure out where this size can be used in order to make an array of the size requested.


Hope it helps and if you have any problems on the way, give me a shout :)
