CircularProgressDrawable

public class CircularProgressDrawable
extends Drawable implements Animatable

java.lang.Object
   ↳ android.graphics.drawable.Drawable
     ↳ androidx.swiperefreshlayout.widget.CircularProgressDrawable


Drawable that renders the animated indeterminate progress indicator in the Material design style without depending on API level 11.

While this may be used to draw an indeterminate spinner using start() and stop() methods, this may also be used to draw a progress arc using setStartEndTrim(float, float) method. CircularProgressDrawable also supports adding an arrow at the end of the arc by setArrowEnabled(boolean) and setArrowDimensions(float, float) methods.

To use one of the pre-defined sizes instead of using your own, setStyle(int) should be called with one of the DEFAULT or LARGE styles as its parameter. Doing it so will update the arrow dimensions, ring size and stroke width to fit the one specified.

If no center radius is set via setCenterRadius(float) or setStyle(int) methods, CircularProgressDrawable will fill the bounds set via Drawable.setBounds(Rect).
