479 Pointscan someone look at my code and tell me where i am going wrong with this challenge?
i don't see where i am going wrong ? Initialize the member variable mExterminateButton using the findViewById() method. The ID for the button is button1. Don't forget to cast the generic View returned by the method!
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
mExterminateButton = (Button) findViewById(R.id.button1);
}
}

479 Pointsok so i got it. can you explain to me why the (m) wasn't necessary ?

10,637 PointsBecause the variable was never declared with the prefix 'm'. You'll run into different code styles in your career of programming. It's good to adapt to them, assuming every variable has 'm' prefixed should not happen.
