Android Question Can I set alpha level of button text in the designer?

[RB Smissaert]

Can't find this.
Looked for a RGBA to hex converter (in code) but couldn't fine one.

This code seems to work in VBA:

Function RGBA2Hex(R As Byte, G As Byte, B As Byte, A As Byte) As String

    Dim lRGB As Long
    Dim lColor As Long

    lRGB = RGB(R, G, B)

    lColor = (lRGB And &HFF00&) Or (lRGB And &HFF0000) \ &H10000 Or (lRGB And &HFF) * &H10000
    
    If A < 128 Then
        If A < 0& Then A = 0&
        lColor = lColor Or A * &H1000000
    Else
        If A > 255& Then A = 255&
        lColor = lColor Or (A - 128&) * &H1000000 Or &H80000000
    End If
    
    RGBA2Hex = Hex(lColor)

End Function

Yes, you can set the button colors with the designer. Change the Drawable to StatelistDrawable.

If you have any other question then please start a new thread.

Yes, I just found out about the StatelistDrawable setting and that does indeed show the alpha setting for the button colour, but as
far as I can see not the button TextColour. Will check again later.

OK, thanks, will check.

But, in B4A, TextColor doesn't have the Alpha level like in B4J or B4i and for the background color.

Indeed, just checked.
You can set it in code though, but not sure it (setting alpha less than 255) actually works.

In the Designer, in B4A, you cannot yet set the Alpha value.
In the code you can !

Will be fixed.
