Initialize the showFactButton variable using the findViewById() method like the TextView above it. The ID for the button

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)!

FunFactsActivity.java
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 {

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

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

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

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

I wonder, is it a question or notification?

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

This would be the answer . The id was showFactButton and to find this we have to go R.id and then the name of the id and we have to cast as a button
