Android Question [B4XPages] Delete view, dynamically created.

vecino · Dec 20, 2020

Hi, how can I delete a view created dynamically?
Thank you.

B4X:

Sub Label6_Click
    Dim pnTr As Panel
    pnTr.Initialize("pnTr")       
    pnTr.Elevation=3dip
    pnTr.Tag=1   
    '   
    Root.AddView(pnTr,0,0,100%x,100%y)   
End Sub

Sub pnTr_Click
    For Each v As B4XView In Root.GetAllViewsRecursive
        If v Is Panel Then
            Dim pn As Panel = v
            If 1=pn.Tag Then
                pn.RemoveView
                Exit
            End If
        End If
    Next
End Sub

the error apparently is not from view removal??

Erel · Dec 21, 2020

The error is probably here:

B4X:

If 1=pn.Tag Then

Change it to:

B4X:

If pn.Tag <> Null And IsNumber(pn.Tag) And 1 = pn.Tag Then
