Public methods

clearAnimationCallbacks

public void clearAnimationCallbacks()

Unregisters all AnimationCallback from this drawable.

createCircularDrawable

public static IndeterminateDrawable<CircularProgressIndicatorSpec> createCircularDrawable(
    Context context,
    CircularProgressIndicatorSpec spec
)

Creates an instance of IndeterminateDrawable for CircularProgressIndicator with CircularProgressIndicatorSpec.

Parameters
`Context context`	The current context.
`CircularProgressIndicatorSpec spec`	The spec for the circular indicator.

createLinearDrawable

public static IndeterminateDrawable<LinearProgressIndicatorSpec> createLinearDrawable(Context context, LinearProgressIndicatorSpec spec)

Creates an instance of IndeterminateDrawable for LinearProgressIndicator with LinearProgressIndicatorSpec.

Parameters
`Context context`	The current context.
`LinearProgressIndicatorSpec spec`	The spec for the linear indicator.

draw

public void draw(Canvas canvas)

Draws the graphics based on the progress indicator's properties and the animation states.

getAlpha

public int getAlpha()

getIntrinsicHeight

public int getIntrinsicHeight()

getIntrinsicWidth

public int getIntrinsicWidth()

getOpacity

public int getOpacity()

hideNow

public boolean hideNow()

Hides the drawable immediately without triggering animation callbacks.

isHiding

public boolean isHiding()

isRunning

public boolean isRunning()

isShowing

public boolean isShowing()

registerAnimationCallback

public void registerAnimationCallback(AnimationCallback callback)

Registers a new AnimationCallback to this drawable. The onAnimationStart() will be called at the start of show animation, or at the moment this drawable is shown, if there's no show animation is used. The onAnimationEnd() will be called at the end of the hide animation, or at the moment this drawable is hidden, if there's no hide animation is used.

Parameters
`AnimationCallback callback`	A new `AnimationCallback` to register.

setColorFilter

public void setColorFilter(ColorFilter colorFilter)

setVisible

public boolean setVisible(boolean visible, boolean restart)

setVisible

public boolean setVisible(boolean visible, boolean restart, boolean animate)

Changes the visibility with/without triggering the animation callbacks.

Parameters
`boolean visible`	Whether to make the drawable visible.
`boolean restart`	Whether to force starting the animation from the beginning.
`boolean animate`	Whether to change the visibility with animation.

Returns
`boolean`	`true`, if the visibility changes or will change after the animation; `false`, otherwise.

start

public void start()

The drawable will start the main animation without show animator.

stop

public void stop()

The drawable will stop the main animation without hide animator.

unregisterAnimationCallback

public boolean unregisterAnimationCallback(AnimationCallback callback)
