Error: can not find symbol class ReletiveLayout.

I am getting a warning:

error: can not find symbol class ReletiveLayout.

I thought that it might be a missing import statement, but that wasn't the problem. See my code:

package calebkleveter.funfacts;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.RelativeLayout;    <========== The import statement is here
import android.widget.TextView;

import java.util.Random;


public class FunFactsActivity extends Activity {

    private FactBook mFactBook = new FactBook();

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

        final TextView factLabel = (TextView) findViewById(R.id.factTextView);
        Button showFactButton = (Button) findViewById(R.id.showFactButton);
        RelativeLayout relativeLayout = (ReletiveLayout) findViewById(R.id.reletiveLayout);
                                                  ^=========== Error here
        View.OnClickListener listener = new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String fact = mFactBook.getFact();
                factLabel.setText(fact);
            }
        };
        showFactButton.setOnClickListener(listener);
    }
}

:) You've spelled relative wrong.

Right-click > Refactor > Rename. And it will update it everywhere.

I want to leave activity_main.xml the same. I want to change MainActivity to Signals from Mars. How is that done?

So you're trying to change the name of 'MainActivity' to be 'Signals from Mars'? If that's the case, it won't work because you can't have spaces in a class name. But you could change it to 'SignalsFromMars' or something like that, by right-clicking on 'MainActivity' (public class MainActivity) and choosing Refactor > Rename.
