CrossfadeDrawable

class CrossfadeDrawable @JvmOverloads() constructor(start: Drawable?, end: Drawable?, scale: Scale, durationMillis: Int, fadeStart: Boolean, preferExactIntrinsicSize: Boolean) : Drawable, Drawable.Callback, Animatable2Compat

A Drawable that crossfades from start to end.

NOTE: The animation can only be executed once as the start drawable is dereferenced at the end of the transition.

Parameters

start

The Drawable to crossfade from.

end

The Drawable to crossfade to.

scale

The scaling algorithm for start and end.

durationMillis

The duration of the crossfade animation.

fadeStart

If false, the start drawable will not fade out while the end drawable fades in.

preferExactIntrinsicSize

If true, this drawable's intrinsic width/height will only be -1 if startandend return -1 for that dimension. If false, the intrinsic width/height will be -1 if startorend return -1 for that dimension. This is useful for views that require an exact intrinsic size to scale the drawable.
