WindowInsetsAnimationCompat

public WindowInsetsAnimationCompat(
    int typeMask,
    @Nullable Interpolator interpolator,
    long durationMillis
)

Creates a new WindowInsetsAnimationCompat object.

This should only be used for testing, as usually the system creates this object for the application to listen to with WindowInsetsAnimationCompat.Callback.

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

Retrieves the translucency of the windows that are animating.

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

Returns the raw fractional progress of this animation between start state of the animation and the end state of the animation. Note that this progress is the global progress of the animation, whereas onProgress will only dispatch the insets that may be inset with inset by parents of views in the hierarchy. Progress per insets animation is global for the entire animation. One animation animates all things together (in, out, ...). If they don't animate together, we'd have multiple animations.

Note: In case the application is controlling the animation, the valued returned here will be the same as the application passed into setInsetsAndAlpha.

public float getInterpolatedFraction()

Returns the interpolated fractional progress of this animation between start state of the animation and the end state of the animation. Note that this progress is the global progress of the animation, whereas onProgress will only dispatch the insets that may be inset with inset by parents of views in the hierarchy. Progress per insets animation is global for the entire animation. One animation animates all things together (in, out, ...). If they don't animate together, we'd have multiple animations.

Note: In case the application is controlling the animation, the valued returned here will be the same as the application passed into setInsetsAndAlpha, interpolated with the interpolator passed into controlWindowInsetsAnimation.

Note: For system-initiated animations, this will always return a valid value between 0 and 1.

public @Nullable Interpolator getInterpolator()

Retrieves the interpolator used for this animation, or null if this animation doesn't follow an interpolation curved. For system-initiated animations, this will never return null.

public void setAlpha(@FloatRange(from = 0.0, to = 1.0) float alpha)

Sets the translucency of the windows that are animating.

Note: This should only be used for testing, as the system fills in the alpha for the application or the alpha that was passed into setInsetsAndAlpha is being used.

public void setFraction(@FloatRange(from = 0.0, to = 1.0) float fraction)

Set fraction of the progress if Type animation is controlled by the app.

Note: This should only be used for testing, as the system fills in the fraction for the application or the fraction that was passed into setInsetsAndAlpha is being used.
