Android Question Limit 3 numbers on edittext

[mscientist33]

I have an EditText that has a default of 000. It is set to numbers only (no decimals). I need the edit text to change as the person clicks the number. Ex: It starts at 000, the user clicks 1 the number should now show 001. Then the user clicks 4 then the number becomes 014 and so on. If the number is say 614 and the user clicks the 5, the edittext should be 145, as each number is pressed it is added to the last digit and drops the first digit to always be three digits. How can this be done? I am not having any luck in the myNumberd_TextChanged event.

Private mChanging As Boolean

Private Sub EditText1_TextChanged (Old As String, New As String)
    If Not(mChanging) Then
        mChanging = True
        Dim v As Int = "0" & New
        EditText1.Text = NumberFormat2(v, 4, 0, 0, False).SubString(1)
        EditText1.SelectionStart = EditText1.Text.Length
        mChanging = False
    End If
End Sub

Set input type to numbers, then:

Private Sub myNumberd_TextChanged (Old As String, New As String)
    If myNumberd.Text.Length > 3 Then
        myNumberd.Text = New.SubString(New.Length - 3)
        myNumberd.SetSelection(3, 0)
    End If
End Sub

Modifying the user text, while the user is writing, usually leads to bad user experience.

Try my routine before writing that ???

@LucaMs , Your code works for me. Is Erel saying it isn't a good way of doing it?

Erel means that the user might see ugly character movements, flickering and the like, but not in this case.
