Hello Team,

We would like to modify some checkboxes in our App so that the small square turns white when they are not selected. How can we achieve this?

B4X: 
If chkLedOnOff.Checked Then
        Sleep(10)
        ChkLedOnOff.Text="Led ON"
        chkLedOnOff.TextColor= Colors.White  
        'chkLedOnOff.TextColor color for the small aquare
    Else
        Sleep(10)
        chkLedOnOff.Text="Led OFF"
        chkLedOnOff.TextColor= Colors.Red
        'chkLedOnOff.TextColor color for the small aquare
    End If

Thank you.

There is a really simple creative solution.

Check out the designer settings of the example you can find in the attachment.
3 views... a blue panel that contains... a small white label and a transparent checkbox.
B4X: 
Private Sub CheckBox1_CheckedChange(Checked As Boolean)
    If Checked Then
        CheckBox1.Text = "Led ON"
        CheckBox1.TextColor = xui.Color_White
    Else
        CheckBox1.Text = "Led OFF"
        CheckBox1.TextColor = xui.Color_Red
    End If
End Sub

You can get something similar to that using SetColorAndBorder of B4XView

B4X: 
Private Sub CheckBox1_CheckedChange(Checked As Boolean)
    Dim BorderColor As Int
    Dim BackgroundColor As Int
    Dim TextColor As Int
 
    BackgroundColor = xui.Color_Blue
 
    If Checked Then
        BorderColor = xui.Color_White
        TextColor = xui.Color_White
    Else
        BorderColor = xui.Color_Black
        TextColor = xui.Color_Red
    End If

    CheckBox1.As(B4XView).SetColorAndBorder(BackgroundColor, 2dip, BorderColor, 0)
    CheckBox1.As(B4XView).TextColor = TextColor
End Sub
[As(B4XView) is not necessary if you have declared the Checkbox as B4XView, which is best done for cross-platform programming]


Anyway, that's exactly why I developed this simple B4XView, to be able to use any image I want (obviously "adding" a Label to it, if it should be a "Checkbox").

@LucaMs , the code you presented doesn't answer the question.
In the OFF state the checkbox square doesn't have a white background!

@PaulMeuris, I wanted to enhance the visibility of the small square borders, as it is initially set to a dark color and my backgroudn is also dark. Thank you for your assistance

@LucaMs I used your link as below, thank you very much it works great!
B4X: 
If chkLedOnOff.Checked Then
        Sleep(10)
        ChkLedOnOff.Text="Led ON"
        chkLedOnOff.TextColor= Colors.White 
        SetButtonTintList(chkLedOnOff, Colors.Red, Colors.Green)
    Else
        Sleep(10)
        'a=ByteA.HexToBytes
        'Manager1.WriteData
        chkLedOnOff.Text="Led OFF"
        chkLedOnOff.TextColor= Colors.Red
        SetButtonTintList(chkLedOnOff, Colors.Red, Colors.White)
    End If
