public class MovieActivity extends Activity {
@InjectView(R.id.titleLabel) TextView mTitleLabel;
@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 :)
}
}
While I am pretty sure this should work the task is failing because it doesnt like the '.' between id and titleLabel. Anyone else having this problem?

Task 2
Now inject a TextView member variable. Name it mTitleLabel and use the ID from the layout file for the movie title TextView.
Your code is following the correct syntax, but if you look in the activity_movie.xml
file, the ID for the title of movies is movieTitle
. You currently are using titleLabel
in your resource reference.
Post back if you are still stuck.
Happy coding,
Ken

Mister Moody
48,333 Points@MUZ140564: Task #3 of the Challenge simply requires you to Add a Single Line similar to the previous statement used to Inject a View: '@InjectView(R.id.movieImage) ImageView mMovieImage;'
By using the 'ID' of said Image View, I was able to correctly answer the question.
Sorry for the poor explanation~ I'm a greehorn developer.
