Android:E/SQLiteLog：（1）没有这样的列：******在“从视图中选择*信息广告，其中******=？”

当我运行我的应用程序时，它崩溃了

E/AndroidRuntime: FATAL EXCEPTION: main

这是我的数据库代码

private static final String mInformationSqlStr =" create table " + InformationDao.TABLE_NAME + " ( "+
            InformationDao.KEY_ID + " integer primary key autoincrement, " +
            InformationDao.KEY_USERNAME + " text not null, " +
            InformationDao.KEY_PSW + " text not null , " +
            InformationDao.KEY_EMAIL + " text ); " ;

    private static final String mAccountDetailSqlStr =" create table  " + AccountDetailDao.TABLE_NAME + " ( "+
            AccountDetailDao.KEY_ID + " integer primary key autoincrement, " +
            AccountDetailDao.KEY_ACCOUNTTYPE + " text not null, " +
            AccountDetailDao.KEY_ACCOUNTNAME + " text not null, " +
            AccountDetailDao.KEY_AMOUNT + " text not null, " +
            AccountDetailDao.KEY_DATE + " text not null, " +
            AccountDetailDao.KEY_COMMENT + " text, " +

    private static final String THEVIEW  = " create view  [view_info_ad] " +
            " AS " +
            " SELECT " +
            "[a].[accounttype]," +
            "[a].[accountname]," +
            "[a].[amount]," +
            "[a].[date]," +
            "[a].[username]," +
            "[b].*" +
            " FROM [detailmessage] [a]" +
            "       LEFT JOIN [userinfo] [b] ON [a].[username] = [b].[username]; ";

我的片段代码

 @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.account_detail_fragment,container,false);
        listview = view.findViewById(R.id.expandablelistview);

        /*(Fragment_Account_Detail.java:41)*/AllData = MyApplication.mdbmaster.mAccountDetailDao.marefuck();


        Child = new HashMap<String, ArrayList<AccountDetailBean>>();

        Child.put(Group.get(0),AllData.get(0));
        Child.put(Group.get(1),AllData.get(1));
        Child.put(Group.get(2),AllData.get(2));
        Child.put(Group.get(3),AllData.get(3));
        Child.put(Group.get(4),AllData.get(4));
        Child.put(Group.get(5),AllData.get(5));
        Child.put(Group.get(6),AllData.get(6));
        Child.put(Group.get(7),AllData.get(7));



        adapter_accountItem = new Adapter_AccountItem(Group, Child,this.getContext());
        listview.setAdapter(adapter_accountItem);
        registerForContextMenu(listview);



        return view;

    }

还有我的sql代码

ublic ArrayList<ArrayList<AccountDetailBean>> marefuck(){
        ArrayList<ArrayList<AccountDetailBean>> result = new ArrayList<ArrayList<AccountDetailBean>>();
        ArrayList<AccountDetailBean> list0 = new ArrayList<>();
        ArrayList<AccountDetailBean> list1 = new ArrayList<>();
        ArrayList<AccountDetailBean> list2 = new ArrayList<>();
        ArrayList<AccountDetailBean> list3 = new ArrayList<>();
        ArrayList<AccountDetailBean> list4 = new ArrayList<>();
        ArrayList<AccountDetailBean> list5 = new ArrayList<>();
        ArrayList<AccountDetailBean> list6 = new ArrayList<>();
        ArrayList<AccountDetailBean> list7 = new ArrayList<>();


        String sql = "select * from view_info_ad where a.username=?";
        /*(AccountDetailDao.java:112)*/Cursor cursor = mDatabase.rawQuery(sql,new String[]{MainActivity.INFORMATIONBEAN.getUsername()});
        while (cursor.moveToNext()){
            String accounttype = cursor.getString(cursor.getColumnIndex("accounttype"));
            String accountname = cursor.getString(cursor.getColumnIndex("accountname"));
            String amount = cursor.getString(cursor.getColumnIndex("amount"));
            String date = cursor.getString(cursor.getColumnIndex("date"));
            AccountDetailBean aaa = new AccountDetailBean().AccountDetailBrief(accountname,amount,date);
            switch (accounttype){
                case "0":
                    list0.add(aaa);
                    break;
                case "1":
                    list1.add(aaa);
                    break;
                case "2":
                    list2.add(aaa);
                    break;
                case "3":
                    list3.add(aaa);
                    break;
                case "4":
                    list4.add(aaa);
                    break;
                case "5":
                    list5.add(aaa);
                    break;
                case "6":
                    list6.add(aaa);
                    break;
                case "7":
                    list7.add(aaa);
                    break;
            }
        }
        result.add(list0);result.add(list1);result.add(list2);result.add(list3);
        result.add(list4);result.add(list5);result.add(list6);result.add(list7);
        return result;
    }

我尝试重新安装我的应用程序，重新创建我的虚拟设备，但没有帮助

我想在expandablelistview上显示消息片段中的内容

我使用sqlite数据库来完成注册和登录任务，这可能不是数据库的问题
