Now let's set the image using the Movie method that gets the appropriate ID. Note: getDrawable(int id) was deprecated in

Help please

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

public class MovieActivity extends Activity {

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

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

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

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

Hi there,

You want to set the member variable mMovieImage to be the right image from the Movie class. You've correctly used the getResources().getDrawable() chain. The parameter for the getDrawable is the returned value of getImageId which you call on the movie instance.

ALL of that is used as the parameter for the setImageDrawable method that you call on the mMovieImage variable. So, you use dot notation on mMovieImage and setImageDrawable() and pass in the whole expression we put together in the first paragraph in the brackets.

You will end up with something like this: 

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

Steve.
