| ↳ | android.graphics.drawable.Drawable | |
| ↳ | android.support.v4.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 setBounds(Rect).
