Initialize the showFactButton variable using the findViewById() method like the TextView above it.

Initialize the showFactButton variable using the findViewById() method like the TextView above it. The ID for the button is showFactButton, and don't forget to cast it to a Button with (Button)!

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

public class FunFactsActivity extends Activity {

    public void onCreate(Bundle savedInstanceState) {

        // Declare our View variables and assign them the Views from the layout file
        TextView factLabel = (TextView) findViewById(R.id.factTextView);
        showFactButton factButton1  = (Button) findViewById(R.id.showFactButton);
       // Button showFactButton;

Hi Josephine,

For this, don't amend the code that's already there; just add the new parts. You've done that correctly.

There'a a Button called showFactButton that equals the ID you've identified.

Button showFactButton = (Button) findViewById(R.id.showFactButton);

Using your code to the right of the equals sign, and the existing code to the left; you get the above.

I hope that helps
