Android Question Label resizing with code problem

You must dim a ColorDrawable for each button!
If you add a routine like this:
And replace everywhere:
xxx.Background = RadiusBlack
by
xxx.Background = SetRadiusBlack
it works OK.
You can of course change the routine above to make it more universal.

In your code you define the colors as Double, they must be Int.

For the TextSizeRatio you use If lv.Width > 1100 Then to define if the device is a 10'' tablet.
This leads to wrong results.
My 5'' Sony xperia Z1 has a width of 1980 pixels and is considered as a 10'' tablet.
You should use lv.ApproximateScreenSize which gives you directly the screen size !

Klaus, Thank you very much for the quick reply and for going above and beyond my question. I will implement these suggestions. I'm still learning how to address the multiple screen size issue as well as just learning the B4 code. You and Erel and the many other helpful people on this site are so appreciated. I am amazed at how you handle the seemingly hundreds of questions posted every day.

Klaus, Your suggestions on setRadiusBlack fixed my problem, thank you very much.
It looks like your suggestion on using ApproximateScreenSize will work great with both my 10" tablet and my 7" but I don't know how to tell when to divide by 10 or by 7 within my code. Is that information supposed to be part of the LayoutValues object? I did some searches on the forum but I didn't see any examples of how to do this.

A function from the module "Scale".

ApproximateScreenSize is part of the LayoutValues object.

Klaus,
For information only:

Bottom line...thank you for your help, and LucaMs too. You guys are great!!!!

Using your and LucaMs's GetDevicePhysicalSize example I get the following results:

GetDevicePhysicalSize = 9.433980941772461 for my Samsung 10.1", 1280x800, scale 1, 160dpi, Android 4.4.2
GetDevicePhysicalSize = 7.823681831359863 for my Rio 9.7", 1024x720, scale 1, 160dpi, Android 4.0.4
GetDevicePhysicalSize = 7.624594688415527 for my Rio 7", 800x444, scale 0.75, 120dpi, Android 4.0.4

So, it appears the formula is not that accurate, however, when I divide lv.ApproximateScreenSize by GetDevicePhysicalSize I get very good aesthetic results, better than dividing by just 10 or 7. My button text now appears proportional across all three screen sizes. I noticed at BestBuy there is an 8" screen on the market too. When will the madness end?

I am also using my TextSizeRatio value for resizing my button widths across the three devices with good success. I don't know if this is recommended but it works. ie;


Thanks again for the help.
