Android Code Snippet [B4X] HexToColor and ColorToHex

Converts hex color strings to a color int value and vice versa:

Private Sub ColorToHex(clr As Int) As String
    Dim bc As ByteConverter
    Return bc.HexFromBytes(bc.IntsToBytes(Array As Int(clr)))
End Sub

Private Sub HexToColor(Hex As String) As Int
    Dim bc As ByteConverter
    If Hex.StartsWith("#") Then 
        Hex = Hex.SubString(1)
    Else If Hex.StartsWith("0x") Then 
        Hex = Hex.SubString(2)
    End If
    Dim ints() As Int = bc.IntsFromBytes(bc.HexToBytes(Hex))
    Return ints(0)
End Sub

Depends on: B4A / B4J - ByteConverter, B4i - iRandomAccessFile

It's occasionally useful to be able to poke around in things as arrays of bytes so this library lets you do it. It can transform arrays of primitive types to and from arrays of bytes with the "endian-ness" of the conversion specified. If you need endian-ness you will either know about it or...
