只贴出了一部分代码，稍微解释一下，即在类中的onCreateView函数中开了一个线程，用来访问网络爬数据，然后生成了5个list，现在想要在getDateFromURL方法中使用这几个list，如何实现？
尝试了使用handler给全局变量赋值，但是getDateFromURL方法中的list都为空，
本人菜鸟，刚学一个月，很多东西都是跌跌撞撞摸索的，求大神指点啊。这地方卡了好久了。目前能想到的思路就两个：1，通过全局变量过度；2，通过数据库来过渡。第二个还没尝试，不知道是否可行。
public class DeckviewFragment extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
mDefaultThumbnail = BitmapFactory.decodeResource(getResources(),
R.drawable.default_thumbnail);
mDefaultHeaderIcon = getResources().getDrawable(R.drawable.banana);
view1 = inflater.inflate(R.layout.deckview, container, false);
mDeckView = (DeckView) view1.findViewById(R.id.deckview);
count = (TextView) mDeckView.findViewById(R.id.count_num);
comment = (TextView) mDeckView.findViewById(R.id.comment_num);
new Thread(networkTask).start();
