Android Question TabStrip - Problem Remove and Insert on a same IndexPage

[scsjc]

Hi,

based in the code: https://www.b4x.com/android/forum/t...-tab-page-programmatically.78631/#post-498276

I think when delete and insert page... the RemovePage dont delete panel inside
And when insert again the Tab in a same index... get error : The specified child already has a parent

Im try to add removepanels inside index with this:

'Return the removed page
Sub RemovePage (ts As TabStrip, Index As Int) As Panel
   If ts.CurrentPage >= Index Then ts.ScrollTo(0, False)
   Dim jo As JavaObject = ts
   Dim p As Panel = jo.GetFieldJO("pages").RunMethod("remove", Array(Index))
   jo.GetFieldJO("titles").RunMethod("remove", Array(Index))

       'remove panel child inside current tab index
       Dim r As Reflector
       r.Target = jo.GetField("tabStrip")
       Dim tc As Panel = r.GetField("tabsContainer")
       tc.RemoveViewAt(Index)

   RefreshTabStrip (ts)
   Return p
End Sub

Im not sure if is correct... but dont work.... the error get is:

java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

You can add p.RemoveView to remove the panel from its parent.
