B4A Class [B4X] [XUI] [custom view] CircularProgressBar

Erel · Jul 13, 2017

This class is compatible with B4A, B4i and B4J.

A simple circular progress bar implemented as a custom view.

Usage:
Add the class to your project and add a custom view with the designer. Set its value with"

B4X:

CircularProgressBar1.Value = 100

The animation is smooth in release mode.

The interesting code is in AnimateValueTo. It implements the animation timeline. You can change the DrawValue implementation to create a completely different animation.

V2.00 is released. It is based on XUI library.

You can prepare a bitmap with the filled circle as you want it. You can then draw it with:

B4X:

cvs.DrawBitmap(BitmapFull, cvs.TargetRect) 'in DrawValue instead of cvs.DrawCircle

how to get it by Panel1.GetView and change value dynamically

Brandsum · Jan 22, 2019

There is a problem. When I set HorizontalAnchor and VerticalAnchor to both sides to place it in the center in designer window, I'm getting this error while loading the layout file.

B4X:

*** Service (starter) Create ***
** Service (starter) Start **
** Activity (main) Create, isFirst = true **
Panel size is unknown. Layout may not be loaded correctly.
Error occurred on line: 39 (CircularProgressBar)
