Guys, this lesson was really weird and confusing. I tried my best to understand what the teacher was soing, but in the end I had no idea. Here is the challenge and I dont know what to do... Please Help!

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 =  findViewById(R.id.showFactButton);

Hey Santiago!

You got it right but you just missed out the cast! Like we did with (TextView), we need one for the data type of (Button). I think you can guess where it goes from the TextView example above ;)

Hope it helps and, if you have any more questions/problems, give me a shout :)
