Ok, but if, I don't want to create new drawable, how to get access to current drawable? – Jekis Osipov Jul 08 '23 at 11:45

@JekisOsipov Try this: `Drawable clone = drawable.getConstantState().newDrawable();` – dinhlam Jul 08 '23 at 13:38
What's about this method for Kotlin? I could not find getConstantState. Thanks – Jekis Osipov Jul 09 '23 at 10:40

For Kotlin, let's use `gettet/setter`, ex: `drawable.constantState` – dinhlam Jul 10 '23 at 03:14
