CircleProgress
CircleProgress is a custom view library for Android that provides reusable UI widgets for rendering circular, donut, or arc-shaped progress indicators. It is designed to help developers visualize task completion status and data progress within native mobile application interfaces.
The component allows for the display of custom text labels and inner graphical assets alongside the progress indicator. It functions by manually calculating paths and arcs on a canvas surface, translating progress percentages into geometric angles to ensure accurate positioning within a circular frame.
The library supports dynamic configuration of visual properties such as stroke width, colors, and progress values directly through XML layout parameters. It maintains the visual state of the progress indicator across configuration changes and triggers redraws whenever progress values are updated to ensure the interface remains synchronized with the underlying data.
