How to manage undo after swipe to delete in android ListView?

Question

I need to implement swipe to delete in a ListView with Undo function as in Gmail App

I know that there are questions already asking about swipe to delete like

Remove item listview with Slide - Like Gmail

and

android swipe to delete list row

But none of them explains how to manage Undo after deletion and Animate back the deleted view on undo!

I found other one with no Answer here

How to implement gmail like Achieve or Undo action in a list item

So here is my question.

How to create a listview in android with swipe to delete then show UNDO in the deleted space and Animate back the same view if the undo is pressed, also remove the undo option on scroll or other item click or swipe?

You smart people have any idea?

| ----------- ITEM 1-----------|

| ----------- ITEM 2-----------|

| --Deleted-------<[UNDO]>|

| ----------- ITEM 4-----------|

| ----------- ITEM 5-----------|

Answer 2

Your question sounds like you're confused about how to manage the actual undo part. If that is the case then I would suggest you look into the design pattern called 'Command Design Pattern'. You can queue up 'Commands' like delete, then only commit them once the undo timer or however you implement it is finished.
