Android Question 6.8 Button Background

[Mashiane]

Hi

I have created a new layout in 6.8, added a button, ran my function to change the button properties...

Button_PowderBlueWhite(btnApply)

'Description: Function to customize your button with backcolor, textcolor, bordercolor, bordersize and radius
'Tag: button, backcolor, textcolor, radius

Public PowderBlue As Int = Colors.rgb(154,217,234)

Sub Button_PowderBlueWhite(btn As Button)
    Fancy_Button(btn,PowderBlue,Colors.White,2,2%x, Colors.black )
End Sub

Sub Fancy_Button(btn As Button, backColor As Int, textColor As Int, borderSize As Int, cornerRadius As Float, borderColor As Int)
    Dim dr As ColorDrawable
    dr.Initialize2(backColor, cornerRadius, borderSize, borderColor)
    btn.Background = dr
    btn.TextColor = textColor
    btn.Invalidate
End Sub

The Error logs..

I have opened an old project with 6.8 that uses these methods, it however works..

Please upload a small project that demonstrates this issue.

Here is it...

Individually, the background of the button works however as soon as there are other controls on the page it crashes, i.e. if you load "vButton" vs "vAddEditWaiter"

Thanks

Moved to the questions forum.

Sub Activity_Create(FirstTime As Boolean)
   'Do not forget to load the layout file created with the visual designer. For example:
   Activity.LoadLayout("vAddEditWaiter")
   Activity.Color = Colors.white
   modThis.Button_PowderBlueWhite(Button1)
End Sub

There is no view named Button1 in vAddEddWaiter layout so it is never initialized.

Damn!!!, thanks Erel, actually my views name is btnAppy and I was passing btnApply. Eish.. You can delete this post as its irrelevant and sorry for the inconvenience. #DontCodeWhenTired!
