Is there a way to sort `RealmResults` by two columns?

I am trying to sort RealmResults by two columns:

RealmResults<User> results = realm.where(User.class).equalTo("relevant", true).findAll();
results.sort("balance", RealmResults.SORT_ORDER_ASCENDING);
results.sort("visible", RealmResults.SORT_ORDER_ASCENDING);
setListViewData(getActivity(), results, true);

But in the listview the results are only sorted by the column visible. So is there a way to sort by two columns?

I am using version 0.75.1.

Hello @zsavely. Until proper support for multi field sorting is added to Realm, there are a few workarounds. The most generic is to make a computed field containing both values (maybe as a string in your case), and then sort by that. That obviously has the drawback of using more space, but only you can know if that’s ok.

In your particular case it looks like one of your fields “visible” might be a boolean, and then you could sort in two steps:

RealmResults<User> results = realm.where(User.class).equalTo(“relevant”, true).findAll(); RealmResults<User> results2 = results.where().equalTo(“visible”, boolean).findAll(); results2.sort(“balance”, RealmResults.SORT_ORDER_ASCENDING);

Hope this helps you until we support multilevel sorting.

Cheers

@njzk2 Not really. The initial report was using single field sorting twice which is sorting two different lists. After that report, we have implemented multi-field sorting.
