Your Activity related to the List.xml should extend from ListActivity class

inside onCreate method

    mInflater = (LayoutInflater) getSystemService(
            Activity.LAYOUT_INFLATER_SERVICE);

    data = new Vector<RowData>();//RowData should get you, your data
    CustomAdapter adapter = new CustomAdapter(this, R.layout.list,
            R.id.title, data);
    setListAdapter(adapter);

Add a new CustomAdapter class

public class CustomAdapter extends ArrayAdapter<RowData> {
    public CustomAdapter(Context context, int resource,
            int textViewResourceId, List<RowData> objects) {               
        super(context, resource, textViewResourceId, objects);
    }

    public View getView(int position, View convertView, ViewGroup parent) {   
        ViewHolder holder = null;

        if(position%2==0)
            convertView.setBackgroundColor(color.darker_gray);
}
