problem with createfromparcel()

THis is the question

Now it's time to work on the CREATOR variable. The first thing we need to do is return a new VideoGame in the createFromParcel() method. Make sure you use the source parameter!

It is showing me an error asking me to use the parcel variable source to create a new video game which i am doing already.. So i don't know why is it showing me an error..

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) {
        // Task 1 code here!
      in.readString();
      in.readInt();
    }

    public static final Creator<VideoGame> CREATOR = new Creator<VideoGame>() {
        @Override
        public VideoGame createFromParcel(Parcel source) {
            // Task 2 code here!
            return new VideoGame(source);
        }

        @Override
        public VideoGame[] newArray(int size) {
            // Task 3 code here!
            return new VideoGame[0];
        }
    };
}

The problem is actually with your answer from part 1 (For some reason it lets you pass without a complete answer).

You need to make sure the values that you are pulling out of the Parcel are being assigned to the member variables. Like this:

public VideoGame(Parcel in) {
        // Task 1 code here!
      mTitle = in.readString();
      mYear = in.readInt();
    }

THanks for the reply.. Can you help me with this question??

I really don't understand how recycle view works. I am comfortable with using the view holder in the list view but i just don't get what is going on with the recycle view.

So how does recycle view work?? What makes it better than the list view with view holder?
