java.lang.OutOfMemoryError。安卓

Question

我在开发我的应用程序方面还没有太远，但我收到了 java.lang.OutOfMemoryError。这是日志猫:

我正在尝试创建一个列表，但每当我检索数据以创建列表时，我都会收到错误。

这是扩展列表 fragment 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)
}
}

这是保存数据的类

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){
    for (Bill b: mBills) {
        if (b.getId().equals(id))
            return b;
    }
    return null;
}

public ArrayList<Bill> getBills(){
    return mBills;
}

}

请帮忙。这是我在大学的最后一个项目，我没有太多时间。谢谢。

您的 for 循环有一个拼写错误: for (int i = 0; 1 < 100; i ++)

应该是i < 100 。由于 1 始终小于 100，因此内存不足。
