java - 将构造函数参数分配给成员变量， ".this cannot be referenced from a static context"

Question

我有课，DFragment 。我正在通过 List<Map<String, String>>到它的构造函数，我需要将传入的值存储在成员变量 subVitalList 中.

我尝试这样做:

this.subVitalList = subVitalList;

但是我在该行收到以下错误:

com.example.DFragment.this cannot be referenced from a static context

我不知道该怎么做。这是 DFragment 的代码:

public class DFragment extends DialogFragment {

    Context context;
    List<Map<String, String>> subVitalList;
    ListView vitalEntryListView;
    LayoutInflater mInflater;

    public static DFragment newInstance(List<Map<String, String>> subVitalList,int i) {
        DFragment f = new DFragment();
        // Supply num input as an argument.
        Bundle args = new Bundle();
        //args.putInt("num", num);
        args.putInt("num",i);

        //List<List<String>> svl = getArguments().getStringArrayList(subVitalList);
        return f;
    }

}

我做错了什么以及如何正确地将传入的值存储在我的成员变量中？

你可以试试这个，

fragment 类，

public class DFragment extends DialogFragment {

    List<Map<String, String>> mylist;

    public DFragment () {   
        // Empty constructor required for DialogFragment
    }

    public DFragment (List<Map<String, String>> mylist) {
        this.mylist= mylist;
    }

}

您可以按如下方式传递列表:

DFragment dialog = new DFragment (mylist);
