Android Code Snippet [B4X] XUI Views - Time Dialog

I want a better dialog for time input so I created this time (picker) dialog using B4X XUI Views and IME library. I think the code has too many lines. Hope someone can simplify or improve it.

Note: I haven't tested but I think this code can also work for B4i and B4J.

Update: I have tested with B4A, B4i and B4J. For B4i and B4J I am not using IME library.

Bug: In B4J, even though I have set the Keyboard Type to Numbers for B4XFloatTextField, I still can enter alphabet which cause the app crashed.


Here is the code for B4A:
Sub Process_Globals
    Private xui As XUI
End Sub

Sub Globals
    Dim IME As IME
    Private dialog As B4XDialog
    Private lblTime As Label
    Private ftfHour As B4XFloatTextField
    Private ftfMinute As B4XFloatTextField
    Private cbAMPM As B4XComboBox
    Dim HH As Int = 12
    Dim MM As Int = 0
    Dim TT As Int = 1
End Sub

Sub Activity_Create(FirstTime As Boolean)
    dialog.Title = "B4AViewTimeDialog"
End Sub

Sub Activity_Resume
End Sub

Sub Activity_Pause (UserClosed As Boolean)
End Sub

Sub Activity_KeyPress (KeyCode As Int) As Boolean 'Return True to consume the event
    If KeyCode = KeyCodes.KEYCODE_BACK Then
        If dialog.Close(xui.DialogResponse_Cancel) Then Return True
    End If
    Return False
End Sub

Sub lblTime_Click
    Dim p As B4XView = xui.CreatePanel("")
    p.SetLayoutAnimated(0, 0, 0, 100%x-40dip, 150dip)
    IME.SetLengthFilter(ftfHour.TextField, 2)
    IME.SetLengthFilter(ftfMinute.TextField, 2)
    ftfHour.TextField.EditTextHint = "12"
    ftfHour.TextField.SetTextAlignment("CENTER", "CENTER")
    ftfMinute.TextField.EditTextHint = "00"
    ftfMinute.TextField.SetTextAlignment("CENTER", "CENTER")
    cbAMPM.SetItems(Array As String("AM", "PM"))
    cbAMPM.SelectedIndex = TT
    dialog.PutAtTop = True 'put the dialog at the top of the screen
    dialog.BackgroundColor = Colors.ARGB(200, 125, 125, 125)
    dialog.ButtonsColor = Colors.RGB(125, 125, 125)
    If HH < 10 Then ftfHour.Text = "0" & HH Else ftfHour.Text = HH
    If MM < 10 Then ftfMinute.Text = "0" & MM Else ftfMinute.Text = MM
    Wait For (dialog.ShowCustom(p, "OK", "", "CANCEL")) Complete (Result As Int)
    If Result = xui.DialogResponse_Positive Then
        If ftfHour.Text = "" Or ftfHour.Text = "0" Or ftfHour.Text = "00" Then HH = 12 Else HH = ftfHour.Text
        If ftfMinute.Text = "" Then MM = 0 Else MM = ftfMinute.Text
        If HH > 12 Then HH = 12
        If MM > 59 Then MM = 0
        If HH < 10 Then ftfHour.Text = "0" & HH Else ftfHour.Text = HH
        If MM < 10 Then ftfMinute.Text = "0" & MM Else ftfMinute.Text = MM
        TT = cbAMPM.SelectedIndex
        Dim strValue As String = ftfHour.Text & ":" & ftfMinute.Text & " " & cbAMPM.GetItem(cbAMPM.SelectedIndex)
        'dialog.Show(strValue, "OK", "", "")
        lblTime.Text = strValue
    End If
End Sub

See how the templates are implemented (unzip XUI Views.b4xlib). You can convert this code to a template class.
Thanks Erel. I will try as your suggestion. Enjoy your holiday!
