Question

我试图从包含cols的表中检索行：

的ObjectID
InvitedId
PartyId
来
createdAt
updatedAt

ACL

ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("PartiesInvites");

ArrayList<ParseObject> partiesId = new ArrayList<>();
for (int i = 0; i < mParties.size(); i++) {
    partiesId.add(mParties.get(i).getObjectId());
    Log.d("UU-UPIL", "partyId = " + partiesId.get(i));
}

query.whereContainsAll("PartyId", partiesId);
query.findInBackground(new FindCallback<ParseObject>() {
    public void done(List<ParseObject> partiesInvitationsIn, ParseException e) {
        Log.d("UU-UPIL", "finding parties invitations");
        if (e == null) {
            for (int i = 0; i < partiesInvitationsIn.size(); i++) {
                Log.v("UU-UPIL", partiesInvitationsIn.get(i).getObjectId());
            }
            mPartiesInvitations = partiesInvitationsIn;
            Log.d("UU-UPIL", String.valueOf(partiesInvitationsIn.size()));
        } else {
            e.printStackTrace();
        }
    }
});

这是我得到的例外

我尝试更改＆＃34; whereContainsAll＆＃34; to＆＃34; whereContainedIn＆＃34;但我一直得到同样的例外。我的代码有什么问题！？

Answer 1

ParseObject子类的默认构造函数不能对导致它变脏的对象进行更改。

我不确定你的代码中是否有某个parseObject的子类用于放入数据库条目，但是在修改该子类的构造函数中的项时会引发此异常

来自Parse.com/android

确保您的子类具有公共默认值（即零参数）构造函数。您不得修改此构造函数中的任何ParseObject字段。

更改此

query.whereContainsAll("PartyId", partiesId);
query.findInBackground(new FindCallback<ParseObject>() {
    public void done(List<ParseObject> partiesInvitationsIn, ParseException e) {
        Log.d("UU-UPIL", "finding parties invitations");
        if (e == null) {
            for (int i = 0; i < partiesInvitationsIn.size(); i++) {
                Log.v("UU-UPIL", partiesInvitationsIn.get(i).getObjectId());
            }
            mPartiesInvitations = partiesInvitationsIn;
            Log.d("UU-UPIL", String.valueOf(partiesInvitationsIn.size()));
        } else {
            e.printStackTrace();
        }
    }
});

到此

query.whereContainsAll("PartyId", partiesId);
query.findInBackground(new FindCallback<ParseObject>() {
    @Override
    public void done(List<ParseObject> partiesInvitationsIn, ParseException e) {
        Log.d("UU-UPIL", "finding parties invitations");
        if (e == null) {
            for (int i = 0; i < partiesInvitationsIn.size(); i++) {
                Log.v("UU-UPIL", partiesInvitationsIn.get(i).getObjectId());
            }
            mPartiesInvitations = partiesInvitationsIn;
            Log.d("UU-UPIL", String.valueOf(partiesInvitationsIn.size()));
        } else {
            e.printStackTrace();
        }
    }
});

基本上只需在完成方法之前添加 @Override

ParseQuery一直都是异常
