B4J Question Sorting list where items start with an integer

[kostefar]

Dear All,

The result of:

Dim l As List
l.Initialize

l.Add("77 a")
l.Add("88 a")
l.Add("880 a")
l.Add("777 a")
l.Sort(True)
For i = 0 To l.Size - 1
  
    Log (l.Get(i))
Next

.. is

77 a
777 a
88 a
880 a

and I want it to be

77 a
88 a
777 a
888 a

It works if I don´t add the numbers as text, but in this case I need to have some text showing in each list item after the number.
Any hints?

Thanks in advance!

Add zeroes ("0") on the left, to have all items with the same lenght.

When you must show them, you can remove the useless zeroes.


[I remember that many "0" must be write "zeroes"; is this correct? ]

I think I get you, so padding 0´s .. if largest number expected is 1000, then you´d add 3 zeros to anything below 10, 2 to anything below 100 etc?

EDIT: Yup, did the trick:

If pct < 10 Then pctstring = "000" & pct
                    If pct > 10 And pct < 100 Then pctstring = "00" & pct
                    If pct > 100 And pct < 1000 Then pctstring = "0" & pct
            ranklist.Add (pctstring & "   " & coin)

And afterwards

Dim rankitem As String = ranklist.get(i)
    If rankitem.StartsWith("000") Then rankitem = rankitem.SubString(3)
            If rankitem.StartsWith("00") Then rankitem = rankitem.SubString(2)
            If rankitem.StartsWith("0") Then rankitem = rankitem.SubString(1)
            Log ("# " & i & " " & rankitem)

You can use both; since I'm old, I will use "zeroes"

Yes

It is like "right alignment" of a text but not in a string with spaces, with zeroes.

Have a look at the List's SortType method

Io si, conosco. Molto utile.

I know. Very useful.

Wow, that´s a nice approach indeed. Came across sort-type before but didnt look into it. Very elegant!

Thanks!
