B4A Library [B4X] [XUI] Gauge View

This custom view class is compatible with B4A, B4J and B4i.

A nice and simple gauge.
You can easily customize it as needed.
It uses the Crystal font: http://www.fontspace.com/allen-r-walden/crystal
There are two types of gauges: half circle and full circle.

Usage instructions:
- Add the class and the font file to your project.
- Add it with the designer and configure it:

- Set the colored ranges:

Gauge1.SetRanges(Array(Gauge1.CreateRange(0, 40, xui.Color_Green), _
   Gauge1.CreateRange(40, 80, xui.Color_Yellow), _
   Gauge1.CreateRange(80, 100, xui.Color_Red)))

- In B4i the font file should be copied to Files\Special and the following line should be added to the main module:

#AppFont: Crysta.ttf

- Animations can be a bit jumpy in debug mode. Should be smooth in release mode.

A B4A project is attached.

See post #10 for adding numbers to the ticks:

Hello,
is it possible to hide the gauge? I can't find any parameter visible = false
Thanks for your help

Make mBase as public variable. This is a convention used in most newer custom views.

Gauge1.mBase.Visible = False

Gauge1.mBase.Visible = False

I'm a newbie, adding this line: Public mBase As B4XView, it doesn't work
Thank

You shouldn't add anything. Go to the Gauge class. Look for mBase global variable and change its visibility modifier from private to public.

Thanks Erel for your rapid answer, I forgotten to set the Alpha to zero... Gauge works fine !!

Hello,
I have the same problem and I don't have the Alpha Level Parameter. My application has a blue background, which distorts the colors. Is there a parameter to have the real colors in the gauge? Thank you
