我正在尝试制作一个列表,无论何时我检索数据以使列表出现错误.
这是扩展列表片段的类
`
public class BillReminderListFragment extends ListFragment {
private ArrayList<Bill> mBills;
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
mBills = BillLab.get(getActivity()).getBills(); <---(this is what is causing the error)
}

public class BillLab {
private ArrayList<Bill> mBills;
private static BillLab sBillLab;
private Context mAppBillContext;
private BillLab(Context appBillContext){
mAppBillContext = appBillContext;
mBills = new ArrayList<Bill>();
for (int i = 0; 1 < 100; i ++){
Bill b = new Bill();
b.setTitle("Bill #" + i);
b.setDate(new Date());
mBills.add(b);
}
}
public static BillLab get(Context c){
if (sBillLab == null){
sBillLab = new BillLab(c.getApplicationContext());
}
return sBillLab;
}
public Bill getBill(UUID id){
