setTitle?

Am I supposed to refer to the Movie class? Am I entering in the wrong parameter?

MovieActivity.java 
import android.os.Bundle;
import android.view.View;

public class MovieActivity extends Activity {

    @InjectView(R.id.movieTitle) TextView mTitleLabel;
    @InjectView(R.id.movieImage) ImageView mMovieImage;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_movie);
        ButterKnife.inject(this);

        // The rest of the code is omitted for brevity :)
    }

    public void updateDisplay(Movie movie) {
        // Add your code here!
        setTitle(mTitleLabel);
    }
}
Movie.java 
public class Movie {
    private String mTitle;
    private int mYearReleased;
    private int mImageId;

    public int getImageId() {
        return mImageId;
    }

    public void setImageId(int id) {
        mImageId = id;
    }

    public String getTitle() {
        return mTitle;
    }

    public void setTitle(String title) { 
        mTitle = title;
    }

    public int getYearReleased() {
        return mYearReleased;
    }

    public void setYearReleased(int year) {
        mYearReleased = year;
    }
}

I'm not sure I understand the question, or the context it is in, to be honest. I'll have a go at being helpful, though!

You've got a method called updateDisplay() and that receives a Movie object as a parameter. This is called movie. The question then goes on to ask you to call a setter method on that object and supply the required parameter. That's the bit I'm not sure about.

I'm going to assume it wants to update the Views in the Activity. For the TextView, that might look something like:

public void updateDisplay(Movie movie) {
        // Add your code here!
      mTitleLabel.setText(movie.getTitle());
    }

Then there's the ImageView to do.

public void updateDisplay(Movie movie) {
        // Add your code here!
      mTitleLabel.setText(movie.getTitle());
      Drawable drawable = getResources().getDrawable(movie.getImageId());
      mMovieImage.setImageDrawable(drawable);
    }

Your updateDisplay method takes a Movie object for a parameter that you are calling movie. You need to call the setter method on that object, and supply the required parameter.
