Reorder items about realm-recyclerview HOT 7 CLOSED

I actually followed that same article as an inspiration for the swipe to dismiss.

Drag and drop should be possible but you would have to have a "order" field on the Realm object so that once a field is dragged around, the underlaying data structure can be updated as well as that the order is persisted between data/screen views.

@kmare - Do you usually have a "order" field in your data structure for this? If so, that should make it possible.
This would be a pretty cool feature to add.

I haven't really started yet working on that feature, but yeah.. I plan on adding an "order" field. I don't think it's possible to (realistically) implement it any other way. Following the mentioned tutorial/links I actually implemented it on a few non-realm (sqlite) projects with custom logic just fine. Unfortunately, I don't think I'll have much time to implement it any time soon for realm-recyclerview, but if I do, I'll gladly send a pull request.

@kmare - sounds good. Yea, I'll see if I can maybe tackle this on the weekend. Should be pretty straight forward as long as I can manage drag/drop updates and realmUpdates. One solution for that might be to turn off Realm updates while the user is dragging items around. Anyhow, I'll dig into it. I'll update this thread once I start working on it so that we don't execute on it in parallel.

Do you have a use-case / would utilize it in one of your apps?

Unfortunately I'll probably have time to work on it in a couple of weeks during the christmas period anyway. Right now I'm not really using realm in a real world project. I'm mainly evaluating it in different use cases for future projects I'd like to work on. So nothing serious at the moment. For now I just built a note/google-keep like app (I know, very original..), adding features just to see what I'd be missing from realm that I wouldn't with normal sqlite operations. So far, I'm not exactly happy with the migration part of realm, but it looks like they're re-implementing it anyway.
Thanks again for your work, it's much appreciated!

It would be really nice if you could just use a RealmList (which is intrinsically ordered) instead of a query result.

It even has a nice move() method to reorder entries: https://realm.io/docs/java/latest/api/io/realm/RealmList.html#move-int-int-

I have a field basis on which I need to sort the list, this field changes on user action rather drag and drop, but changing the order at run time adding one more extra element also randomly replacing other elements. Thought this issue is relevant here.

Hi I wondered if anyone started working on this feature?
