Android Question Cast a string to EditText

[forisco70]

Hi to all! With this code i obtain an error:

Private Sub clickDate_Click
    Dim btnDate As ImageView = Sender
    Dim edtText As EditText = btnDate.Tag
    selectionDate(edtText)
  
End Sub

Private Sub selectionDate (dateField As  EditText)
    dateField.Text = DateTime.Date(DateTime.Now)

End Sub

What's the right way to pass a string as a valid EditText? Thanks!

there is no way - right or wrong. i'm guessing that's exactly what you saw when you tried to run your project

btnDate.Tag is an object. as such it can be a string (if you like) or an edittext. technically, there is nothing wrong with:
[CODE lang="b4x"]
Dim edtText As EditText = btnDate.Tag
[/CODE]
assuming Sender's tag is an edittext. in this case, somewhere up the line of your crisscross code there is an imageview. set its tag to an edittext. if you set a view's tag to a string, then it can't be cast as a view.

Why don't use String variable?

Thanks to both of you, friends! In the designer mode, i don't know how to set the tag property of an imageview to an edittext! Anyway, i solved in this way: i set up tags of the imageviews as 1, 2, 3, ... and then i wrote this code in the clickDate event:

Dim btnData As ImageView = Sender, indice As Int = btnData.Tag
    ' something for mydate'
        Select indice
            Case 1
                edt1.Text = myDate
            Case 2
                edt2.Text = myDate
            Case 3
                edt3.Text = myDate
        End Select
    End If

For now, all works fine! Bye!!!

Better to use a Map:

Private edts As Map = CreateMap("1": edt1, "2": edt2, "3": edt3)
'And later
edts.Get(btnData.Tag).As(B4XView).Text = myDate

You are right, Erel, it's better! Bye!
