Android Build an Interactive Story App User Input Finding Views by IDs

I need help with findViewId() Code Challenge!

Hello All,

I'm having trouble here on this code challenge. I cannot seem to input the correct values to pass this challenge. I'm supposed to initialize the member variable exterminateButton using the findViewById() method. The ID for the button is 'button1'. I'm also supposed to cast the generic View returned by the method. Can someone please point out where I went wrong in this challenge?

MainActivity.java
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity {

    protected Button exterminateButton;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Declare our view variables
        exterminateButton = (Button)findViewById(button1);
    }

}

It should be R.id.button1 instead of just button1
