Weather app giving empty list

Not sure what is going on but when i fisnihed the list view data it comes up with empty data. When then found out i was not using setListAdapter it then just started crashing. 

public class DailyForcastActivity extends ListActivity {


    private Day[] mDays;
    @Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_daily_forcast);

        Intent intent = getIntent();

        Parcelable[] parcelables = intent.getParcelableArrayExtra(MainActivity.DAILY_FORCAST);

        mDays = Arrays.copyOf(parcelables,parcelables.length,Day[].class);

        DayAdapter adapter = new DayAdapter(this,mDays);

        setListAdapter(adapter);

    }


}

Hi Alex, Your post was really helpful, because I also forgot to add setListAdapter. Now my List View works with no problem. If you still didn't solve your problem with a List View I'm ready to help.
