1，申明fragment 例項程式碼

Bundle bundle = new Bundle();
			bundle.putString("opt", navigateIndustry.getOpt().toString());

SelectedIndustryFragment selectedOneFragment = SelectedIndustryFragment.newInstance(bundle);
			lastlistfragmentView.add(selectedOneFragment);

public class SelectedIndustryFragment extends Fragment {
	private PullToRefreshListView lv_today_information;
	private List<NewsTop> todayHotNewslist = new ArrayList<>();// 今日要聞list資料
	private ListView actualListView;
	private ListTodayNewsAdapter listTodayNewsAdapter;
	// private ProgressBar pb_todayInfo;
	MyDatabaseHelper dbHelper;
	private SystemCache systemCache;
	private final int CacheTime = Constant.DEFALUT_CACHETIME;
	private final String HotNewsFragment = SelectedIndustryFragment.class.getSimpleName();
	private String TodayNewsCache;
	private MyToast myToast;
	private MyApplication myApplication;
	private boolean isPause = false;
	private String opt;
	private Context mcontext;

	static SelectedIndustryFragment newInstance(Bundle b) {
		SelectedIndustryFragment selectedOneFragment = new SelectedIndustryFragment();
		selectedOneFragment.setArguments(b);
		return selectedOneFragment;
	}

	@Override
	public void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		opt = getArguments().getString("opt");
	}

	@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		View view = inflater.inflate(R.layout.hotnewsfragment_layout, container, false);
		mcontext = getActivity();
		initView(view);
		showData();
		return view;
	}
