Android Build a Weather App (2015) Hooking Up the Model to the View Using Butter Knife for Views

Task 2 of 3

import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import android.widget.ImageView;

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?

MovieActivity.java
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import android.widget.ImageView;

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 :)
    }
}

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

That did it, thanks.

send an example of this code please thanks

its not working

import android.os.Bundle; import android.view.View; import android.widget.TextView; import android.widget.ImageView;

public class MovieActivity extends Activity {

    @InjectView(R.id.movieTitle) 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 :)
}

}

how is task 3 of this challange completed?I am stuck

@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.
