# CircularProgressDrawable
| This package is part of the Android[support library](https://developer.android.com/topic/libraries/support-library)which is no longer maintained. The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings).

| | ↳ | 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()](https://developer.android.com/reference/android/support/v4/widget/CircularProgressDrawable#start())and[stop()](https://developer.android.com/reference/android/support/v4/widget/CircularProgressDrawable#stop())methods, this may also be used to draw a progress arc using[setStartEndTrim(float, float)](https://developer.android.com/reference/android/support/v4/widget/CircularProgressDrawable#setStartEndTrim(float, float))method. CircularProgressDrawable also supports adding an arrow at the end of the arc by[setArrowEnabled(boolean)](https://developer.android.com/reference/android/support/v4/widget/CircularProgressDrawable#setArrowEnabled(boolean))and[setArrowDimensions(float, float)](https://developer.android.com/reference/android/support/v4/widget/CircularProgressDrawable#setArrowDimensions(float, float))methods.
To use one of the pre-defined sizes instead of using your own,[setStyle(int)](https://developer.android.com/reference/android/support/v4/widget/CircularProgressDrawable#setStyle(int))should be called with one of the[DEFAULT](https://developer.android.com/reference/android/support/v4/widget/CircularProgressDrawable#DEFAULT)or[LARGE](https://developer.android.com/reference/android/support/v4/widget/CircularProgressDrawable#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)](https://developer.android.com/reference/android/support/v4/widget/CircularProgressDrawable#setCenterRadius(float))or[setStyle(int)](https://developer.android.com/reference/android/support/v4/widget/CircularProgressDrawable#setStyle(int))methods, CircularProgressDrawable will fill the bounds set via[setBounds(Rect)](https://developer.android.com/reference/android/graphics/drawable/Drawable.html#setBounds(android.graphics.Rect)).
