Weather app - Phase 2 - Unable to follow along with Ben (Adapter)

While following along with the video, I am attempting to add the line of code that is demonstrated from the video and it is not working. I am not sure why this is.

Here is my code

package rythmair.com.stormy.ui;

import android.app.ListActivity;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListAdapter;

import rythmair.com.stormy.R;

public class DailyForecastActivity extends ListActivity {

    @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);

}

Just below android.R.layout.simple.... , Ben is asking that the following be added.

setListAdapter(adapter);

However, I cannot add this as I am getting the following error.

Invalid method declaration, return type required.

I have been working through the weather app from the beginning and do not recall creating a method called setListAdapter.

Please advise.

You're putting your code outside of the onCreate() method. It needs to be moved up inside of the curly braces so it looks like:

public class DailyForecastActivity extends ListActivity {

    @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);
    }
}

Ah, shoot!

Thank you, Seth.

Can't believe I did that.
