What's wrong with it? It can not identify TextView?

No idea why there is compiler error.

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

@InjectView(R.id.movieTitle) TextView mTitleLabel;

public class MovieActivity extends Activity {

    @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 :)
    }
}
activity_movie.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white" >

    <TextView
        android:id="@+id/movieTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="32sp"
        android:text=""
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true" />

    <ImageView

        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@id/movieTitle" />

        android:layout_centerHorizontal="true"
        android:id="@+id/linearLayout">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text=""
            android:id="@+id/textView"
            android:layout_weight="1"

        <TextView

            android:layout_height="wrap_content"
            android:text=""
            android:id="@+id/textView2"
            android:layout_weight="1"
            android:gravity="right" />

    </LinearLayout>

</RelativeLayout>

Your @InjectView is outside the class. Move it inside MovieActivity and it'll work fine.

Oh God, I think I need a refresh of my brain. Thank you so much!

I know that feeling well! A few hours of staring at code and I go blind to the errors.
