Can anyone help me with this challenge?
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 = findViewById(R.id.button1);
}
}

Treehouse TeacherHi there, Derek Lam! The findViewById
part is fine. However, that returns a view and not a Button
. The last line in the instructions says to not forget to "cast" the view into a Buttton
.
Right now you have:
exterminateButton = findViewById(R.id.button1);
But you would need:
exterminateButton = (Button)findViewById(R.id.button1); // cast the view into a button
Hope this helps!
