I have not run your code, but there may be several issues at play:
DragLinearLayout
requires you to useremoveDragView()
instead ofremoveView()
. (It is a flaw in the library that it does not enforce this properly.) Easiest fix would be to use the former instead of the latter. Note that there is also no need to callsetViewDraggable()
as you do right before removing it, sinceaddDragView()
makes it draggable.- You are iterating over the Views in your ViewGroup as you are moving them around. An in-place sort is bound to cause issues if you don't carefully keep track of your loop counter, e.g. consider the case:
- Iteration 0
[A B C D]
-> remove View at position 0, i.e. A
[B C D]
-> move View A to saved position, e.g. 1
[B A C D]
- Iteration 1
[B A C D]
-> remove View at position 1, i.e. A
[B C D]
-> move View A to saved position, 1 again
[B A C D]
..
i.e. B is never processed. It may be simpler to remove all the Views first and then add them in the right order.
Depending on your use-case, you may be better off creating and binding Views dynamically with an adapter, e.g. by using a RecyclerView
instead of DragLinearLayout
. ItemTouchHelper
can provide drag and drop support. You can find a good overview and tutorial here.

Hi,
I've solved using RecyclerView
. Do you know how to add items to Array to a specific index which is saved into SharedPreferences? So I can restore the buttons order when the App is launched. Thanks again!
