Hi, i'm trying to use the AHSwipeToRefresh library with XCustomListView but it gives me the following error. Is there any way to use this fantastic library with XCustomListView?

B4X:
*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Error occurred on line: 39 (Main)
java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

Ok, the solution was to remove the view of the activity before.

B4X:
'It is not possible to add child objects to custom views in the designer.
    'So we have to add the listview manually here.
    RemoveView(CustomListView1.AsView)
    STR.AddView(CustomListView1.AsView)
call this sub:

B4X:
Sub RemoveView (V As View)
    For i = 0 To Activity.NumberOfViews - 1
        If Activity.GetView(i) = V Then
            Activity.RemoveViewAt(i)
            Exit
        End If
    Next
End Sub
I upload the corrected project.

Regards.
