User Input Challenge

Dear all,

How to start for User Input Challenge?

Thanks

Jonathan

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

public class MainActivity extends Activity {

    protected Button mExterminateButton;

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

        // Declare our view variables

    }

}

Under the comment // Declare our view variables on the next line start with:

mExterminateButton = ???

As the Task says, you need to initialize mExterminateButton with findViewBy(). You will need to pass an int id to findViewById() which you can get with R.id.your_id_here. Finally, remember to cast the generic View returned by findViewById() to the specific type you want, in this case a Button. Hope that gets you started.
