Two potential things,

You haven't initialized a button like this. private Button showFactButton;

Or you haven't found the id

showFactButton = (Button) findViewbyId(R.id.showfactbutton);

Apart from that my guess is as good as yours

Hello guys, Im having this issue(.setOnClickListener is showing in red):

public class FunFactsActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fun_facts);
}
// Declare our View variables and assign the views from the layout file.
final TextView factLabel = (TextView) findViewById(R.id.factTextView);
Button showFactButton = (Button) findViewById(R.id.showFactButton);
View.OnClickListener listener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //The button was clicked, so update the fact label with new fact
        String fact = "Cristo es que salva!";
        factLabel.setText(fact);

    }
};
showFactButton.setOnClickListener(listener);

}
