B4J Question change colour of button [Solved]

Peter Lewis · Apr 12, 2020

Hi All

I am looking to change the button background of a button to either green or Red depending on when the button is clicked.

In the clicked code I can put the statement there but there are no color options i can see when I put the button. code , only a button text color appears

Any ideas ?

Thank you

in b4a there is a lovely thing called state drawable the button changes background (even an image, if you use one for a button's background) on tap and on release.
i'm not sure if the same thing exists in b4j. i could only find this see what you can dig up.

I found that a few hours ago but it would not work due to missing library, do you know which lib it is , I clicked on a lot but did not make any difference. B4J

StateListDrawable will not work with B4J as it is an Android feature.

You can use CSS to do it: https://www.b4x.com/android/forum/threads/css-example.35854/#content
Or use SwiftButton from XUI Views.

Thank you for that.

Would I be able then to change the colour of the background of the button depending on the data from a database in real-time ?

With SwiftButton you should be able to do it.

I have tried looking over the forums with the structure of SwiftButton, I also downloaded the examples and No where I could find has the button color change structure.

I am sure it can do it . Is there any Manual on SwiftButton

Nothing I have tried works. Anexample

B4X:

    btn1.xLBL.Color.XUI.Color_Red

This Worked now

B4X:

btn1.xLBL.Color=xui.Color_Green
