WindowInsetsAnimationControllerCompat

public void finish(boolean shown)

Finishes the animation, and leaves the windows shown or hidden.

After invoking finish, this instance is no longer ready.

Note: Finishing an animation implicitly sets insets and alpha according to the requested end state without any further animation.

public float getCurrentAlpha()

Current alpha value of the window.

public @FloatRange(from = 0.0, to = 1.0) float getCurrentFraction()

Returns the progress as previously set by fraction in setInsetsAndAlpha

public @NonNull Insets getCurrentInsets()

Retrieves the current insets.

Note that these insets are always relative to the window, which is the same as being relative to getRootView

public @NonNull Insets getHiddenStateInsets()

Retrieves the Insets when the windows this animation is controlling are fully hidden.

Note that these insets are always relative to the window, which is the same as being relative to getRootView

If there are any animation listeners registered, this value is the same as getLowerBound that is being be passed into the root view of the hierarchy.

public @NonNull Insets getShownStateInsets()

Retrieves the Insets when the windows this animation is controlling are fully shown.

Note that these insets are always relative to the window, which is the same as being relative to getRootView

If there are any animation listeners registered, this value is the same as getUpperBound that is being passed into the root view of hierarchy.

public int getTypes()

public boolean isCancelled()

Returns whether this instance has been cancelled by the system, or by invoking the android.os.CancellationSignal passed into controlWindowInsetsAnimation.

public boolean isFinished()

Returns whether this instance has been finished by a call to finish.

public boolean isReady()

Returns whether this instance is ready to be used to control window insets.

Instances are ready when passed in onReady and stop being ready when it is either finished or cancelled.

public void setInsetsAndAlpha(
    @Nullable Insets insets,
    @FloatRange(from = 0.0, to = 1.0) float alpha,
    @FloatRange(from = 0.0, to = 1.0) float fraction
)

Modifies the insets for the frame being drawn by indirectly moving the windows around in the system that are causing window insets.

Note that these insets are always relative to the window, which is the same as being relative to getRootView

Also note that this will not inform the view system of a full inset change via dispatchApplyWindowInsets in order to avoid a full layout pass during the animation. If you'd like to animate views during a window inset animation, register a WindowInsetsAnimationCompat.Callback by calling setWindowInsetsAnimationCallback that will be notified about any insets change via onProgress during the animation.

dispatchApplyWindowInsets will instead be called once the animation has finished, i.e. once finish has been called. Note: If there are no insets, alpha animation is still applied.
