[Android] DragAndDropEndedCommand called before the item is reordered in the collection

[InquisitorJax]

Platform :

• OS: Android

Description
In the AndroidHorizontalListViewRenderer, line 120, the command is called before the list is reordered. This means when the handler for the command is executed, the list is still in the order before the drag and drop takes place.

Fix

Move _onDragAndDropdEnded?.Execute(null); line to after the collection is modified.

A simple workaround for this issue (if you can't wait for the fix) is to use the ChildrenReordered event from the HorizontalListView.

In my case, I wanted to know when the list was reordered, in order to adjust the index numbers of each list item.
