I "simply" wish to slow down the open/close animation on a DisclosurePanel.
Any ideas how to do this?
I see;
private static final int ANIMATION_DURATION = 350;
in the class. But the class cant be extended for some reason, so is there alternatives/workarounds?
I am afraid it is impossible. I had some problems with DisclosurePanel as well (it is based on and was not fitting well to my layout) and I just created my own collapsible panel. It turned out to be very easy. So if you want to have more controll over the animation or anything else I recommend you to write it by your self.
