Android Question Problem with edittext.requestfocus

[oniblabp]

Hello everyone. First post ever here. So please be gentle.

The code i'm having trouble is this one:

Private Sub cmdBuscar_Click
    If FueraDeLinea Then
        ToastMessageShow("Fuera de Linea",False)
        MostrarControles(True)
        txtConteo.RequestFocus
        txtConteo.SelectAll
    Else
        Dim j As HttpJob
        Dim Encontrado As Boolean
        j.Initialize("j",Me)
        j.PostString("http://" & APIServer.Trim & "/api/v1/buscarproducto.php","codigo=" & txtCodigo.Text)
        j.GetRequest.SetContentType("application/x-www-form-urlencoded")
        wait for (j) JobDone(j As HttpJob)
        If j.Success Then
            Dim Leido As String
            Leido=j.GetString
            Log(Leido)
        
            If Leido.Trim.Length>0 Then
                If Leido.Contains("fail")=False Then
                    Encontrado=True
                    ToastMessageShow("Encontrado",False)
                    Dim parser As JSONParser
                    parser.Initialize(Leido)
                    Dim root As List = parser.NextArray
                    For Each colroot As Map In root
                        Dim descripcion As String = colroot.Get("descripcion")
                        Dim equivalencia As String = colroot.Get("equivalencia")
                        Dim prodid As String = colroot.Get("prodid")
                        Dim cantidad As String = colroot.Get("cantidad")
                    Next
                
                    txtProdid.Text=prodid
                    txtEquivalencia.Text=equivalencia
                    txtDescripcion.Text=descripcion
                    txtExistencia.Text=cantidad
                
                    MostrarControles(Encontrado)
                
                    txtConteo.RequestFocus
                    txtConteo.SelectAll
                Else
                    Encontrado=False
                    MostrarControles(Encontrado)
                    ToastMessageShow("No encontrado",False)
                    txtCodigo.RequestFocus
                    txtCodigo.SelectAll
                End If
            End If
        Else
            ToastMessageShow("No pude comunicarme con server API",False)
        End If
        j.Release       
    End If
End Sub

Private Sub txtCodigo_EnterPressed
    cmdBuscar_Click
End Sub

IF i use the keyboard in my cellphone to enter a not existent code and press the "BUSCAR" button, it shows the ToastMessage indicating that it's offline, and it sets the focus on txtConteo properly. I can see the cursor blinking in the field whether it has a value or not.

BUT if i use a codebar reader, it reads the not existent code, shows the ToastMessage but no edit text view gets the focus. So, if i read another code inmediatly using the scanner, or if i press RETURN in the android keyboard, the app crashes. The app just closes.

I've tried changing the "code end char" on the reader, from ENTER (0x0d) to RETURN (0x0a). Same result.

The only way it works it's configuring the scanner to not sending an ENTER or RETURN. But the user is forced to press the button "BUSCAR".
With 30 codes to scan it's maybe nothing. But when there are 3000 codes to scan, it's not functional.

If anyone could shed a light on this issue, i would appreciate it.

Thanks in advance and BTW, what an excellent language is B4A. I'm loving it so far.

OK, so far i found that the focus goes to my Exit Button. So when i scan again with the barcode scanner, it hits enter and the app ends.
So the problem is that txtConteo.requestfocus is not working when the barcode scanner triggers.

The problem continues....

Try to use IME.AddHandleActionEvent instead of EnterPressed: https://www.b4x.com/android/forum/t...-keyboard-with-the-ime-library.14832/#content
It allows you to intercept the enter button without removing the focus.
