I want to create animation for my fab like this example in material design principle, I realized that icon inside fab has 2 animation. One that rotate share icon and another is alpha animation simultaneity. after that another icon replaced. but when I create animation set for this goal, whole fab rotated and disappeared, but I want that icon inside fab take this animation. How can I create this animation? thanks
The best way to achive that is create a Custom Floating action button class and Override your setImageDrawable method, doing the translation animation there. Also you can modify your onDraw method to add an animation to your FloatingActionButton
You have to use a third-party library to achieve this result. Take a look here It is important to notice that it is possible to implement your own way but you would be kind of "reinventing the wheel".
If you want to do this anyway, you can create several FABs and change visibilities and move them with simple animations.

Did someone already achieved to transform an extended FAB into standard FAB and vice-versa ? I know how to add a FAB into my layout and how to detect the list scroll threshold but i really don't know how to achieve this transformation (Please see the reference to see what i would like to do : Extented FAB into standard FAB).
Thank you a lot
Kind regards
Just add 2 magical lines for this behavior this code only works for ExtendedFloatingActionButton
floatingButton.shrink(); ///This line of code hide text and show Icon of floating buttion
floatingButton.extend()///This line of code show text and icon of floating button
According to the material design guideline
"The floating action button can transform into a single sheet of material which contains all the actions".
I want to create the following animation without using third party libraries.
First you need to cut that animation in small parts.
In that example i can deduce 3 steps:
a Ripple effect on the FAB triggered on click event.
a translation to the left applyed to the FAB.
a Circular Reveal animation applyed to the card.
So you need to create a FAB (visible) and a card (invisible). The FAB at it initial position and the card to it final one. After having triggered the ripple effect on the FAB (step 1) and at the end of your move event on FAB again (end of step 2), you just need to dismiss the FAB and start the Reveal animation on the card (step 3).
To launch a circular reveal animation, just call the ViewAnimationUtils.createCircularReveal method. Pass your card view, the X,Y start coordinate, the radius and that's it! The difficulty will definitely be to find the best duration and start/end coordinate between each animations to set it as smooth as possible.
If you want, you can look my post here https://stackoverflow.com/a/41957295/1053880. I used a circular reveal animation to create a switch between two toolbars. Some part of your code will be similar to mine (i also reverted my anim at the end).

When I call toolbar.startActionMode(...) it defaultly see a fade animation, I would like to change that to a slide animation. As I can just touch the Toolbar view directly, I don't know how to do this.
I can do this by using 2 toolbars and just animate the second one. But as the Toolbar provides an action mode and I already use it, I would like to know if I somehow can modify it's animation...
Android doesn't give you access to the ActionMode "toolbar". Which by the way is not a Toolbar. The type of the context "toolbar" is ActionBarContextView.
If you want full control you need to implement your own Action Mode with 2 toolbars. Then u can add the animation you desire.
The Material Design Guidelines suggest that you transition a floating action button into a new Activity, after you click on the button.
Example Video from Guidelines
I tried to animate this with Activity transition, as intoduced in API 21 (Lollipop) but I can't find a way to transform from the color of the button to the color of the toolbar. (I used this Floating Action Button)
Obviously, the example isn't an actual demo running on android, but the device that is displayed is clearly a smartphone. Therefore there has to be a way to code this kind of transition, or else Google would not have added this on their Guidelines, would they?
Can I use Activities to achieve this or do I have to use Fragments?
As FloatingActionButton descends from ImageButton and adds only a few new methods,you can use setBackgroundColor() of ImageButton to change its background.
I want to create sliding buttons in Android,
When we slide up the light indicator will glow, as we need change image while sliding it.
I have tried with toggle button and switch but its not having sliding effect?
Any suggestion on this.
Try to use thus library. When you will download it try to set your custom theme and get the solution.
