Exactly like in B4A.

TextField.Text = NumberFormat(x, 1, 0)

my question is not clear!

True.

No such thing.
Possible options:
- Use B4XInputTemplate with B4XDialog and configure it to accept numbers.
- Check the value with IsNumber before you use it.
- Handle TextChanged and change the border to red (with XUI) when IsNumber = False.

use this

Sub txt_tell_TextChanged (Old As String, New As String)
    Dim update As Boolean
    
    Try
        Dim text As String = Regex.Replace("\D",New,"")
        If New <> text Then
            update = True
        End If
    Catch
        Log(LastException.Message)
    End Try
    
    If text.Length >= 18 Then   ' 18 is the max length allowed you can change this :)
        text = text.SubString2(0,18)
        update = True
    End If
    
    If update Then
        txt_tell.Text = text
        txt_tell.SetSelection(text.Length,text.Length)
    End If
End Sub
