Hey all,

I can't change the (back)color of my radiobuttons. Trying drawable is also not working. Trying a canvas crashes the app.

I've tried in designer, connected to my device (SE Xperia Arc S) and got no results. Tried it with code, also no result.

The color remains transparent... Any1 an idea?

Greetings,
Sigurd

Seems to be working here. I changed the color with the designer and it works. Make sure that you also change the transparent value:


You should also be able to use a canvas with RadioButton. Make sure that the RadioButton is first initialized (if created programmatically) and added to the activity before initializing the canvas.

Hey Erel,

I can't get it to work. See my code below please. It should add a semi-transparent red background to the radiobuttons. You can see the result on my SE Xperia Arc S on the screenshot I took.

B4X: 
Dim rdbDepartmentList As RadioButton: rdbDepartmentList.Initialize("rdbDepartmentList")
rdbDepartmentList.Text = objMap.Get("CONT_CODE"): rdbDepartmentList.Tag = objMap.Get("CONT_ID")
rdbDepartmentList.TextSize = 16
Dim objColor As ColorDrawable: objColor.Initialize(Colors.ARGB(150, 255, 0, 0), 10)
rdbDepartmentList.Background = objColor
vscDepartment.Panel.AddView(rdbDepartmentList, Design.Padding, intPosY, vscDepartment.Panel.Width, Design.LabelHeight)
Greetings,
Sigurd

Try this code:
B4X: 
Dim b As Button
b.Initialize("")
Activity.AddView(b, 0, 0, 100dip, 100dip)
Dim rdbDepartmentList As RadioButton
rdbDepartmentList.Initialize("rdbDepartmentList")
rdbDepartmentList.Text = "sdf"
rdbDepartmentList.TextSize = 16
Dim objColor As ColorDrawable
objColor.Initialize(Colors.ARGB(150, 255, 0, 0), 10)
rdbDepartmentList.Background = objColor
Activity.AddView(rdbDepartmentList, 0, 0, 200dip, 200dip)

This is what I get:

Hey Erel,

This is weird. I get the attached image (with project attached).

What could this be?

Greetings,

That is possible of coarse. Can somebody else please try this project on their device?

I've added a panel behind the radiobutton. This works fine, but I need to create an extra view per radiobutton this way. This results in a performance penalty. My Xperia is quite fast (1.4GHz) so here it is not noticable. I'll have to test this further. Thanks for the tip and help.
