How can I move list view items?

[Hossein_Jafarian]

Hello.
I have a list view and I want to be able to move a selected item up and down in the list using two buttons, up and down.

Here is a probable way using an extension

Colin Tree List view sorting ascending & descending

Great Tim, now i could manage to move the elements step by step in the listview. [grafik] Move_up button is equivalent.

Here is a blocks only sample:

How do you create an ordered list from checkbox entries?

Regarding maintaining list order, here is my To Do list app, which gives complete control over selection and order. ToDo.aia (7.2 KB) (editted) No dictionaries are used, just plain lists. Gallery link: https://gallery.appinventor.mit.edu/?galleryid=101e953e-a66f-458e-8fa1-4e4026f01e6c
