Cant add SimpleAdapter?

import android.os.Bundle;
import android.widget.SimpleAdapter;

public class WebsiteListActivity extends ListActivity {

    public static final String KEY_NAME = "name";
    public static final String KEY_URL = "url";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_website_list);

        String[] keys = { KEY_NAME, KEY_URL };
        int[] ids = { android.R.id.text1, android.R.id.text2 };

SimpleAdapter adapter = new SimpleAdapter(this,website,android.R.layout.simple_list_item_2,keys,ids);

        // Add code here!
    HashMap<String, String> website1 = new HashMap<String, String>();
    HashMap<String, String> website2 = new HashMap<String, String>();

  website1.put(KEY_NAME, "Treehouse");
  website1.put(KEY_URL, "http://teamtreehouse.com");
  website2.put(KEY_NAME, "Tyranski");
  website2.put(KEY_URL, "http://tyranski.com");

       ArrayList<HashMap<String, String>> websites = new ArrayList<HashMap<String, String>> ();
  websites.add(website1);
  websites.add(website2);
    }
}
