The code you are writing should go inside the curly-braces of the onCreate method. You should notice that the auto-complete it gave you for setListAdapter (overriding and creating a new method definition) is not the same code as in the video (simply calling the method).

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

    String[] daysOfTheWeek = { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday" };
    ArrayAdapter<String> adapter= new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1 ,daysOfTheWeek);
    setListAdapter(adapter);
}
