I will cover everything in my ConstraintLayout tutorial as soon as the stable releases are out

That motion design tool in Android Studio is dope. Can't wait to try it out!

Notes from this presentation: 1. ConstraintLayout now works with custom views 2. Convert Views straight from right-click context menu. Suggestions offered are contextual; intelligently offered based on the type of View selected. 3. Navigate to and from`included` layout via siongle click in the Component tree 4. Improved menu options to aid to View position. This avoid writing too much XML by hand 5. Tools attribute give additional info to the layout editor. Useful especially in contexts where data is remote or unavailable any design time e.g for RecyclerViews, ImageViews 6. Sample Data: provide data, that is normally not available at design time: @sample/. Can use both built-in data or create data In files in a sample data folder at the root directory of the project.Sample data can be complex JSON too: album.json/title, album.json/artists/lead 7. Design Time Helper: “wrench” icon in the Bottom-Left of a View in Design View. Helps select Sample data 8. Helper objects - barriers , guidelines. These are not view groups, hence, the ConstraintLayout remains flat. A single View can be referenced in multiple Helpers Layout Manipulation: e.g Linear, Flow Post-layout Manipulation: Rendering/Decorating Layers: 9. Declare ConstraintSets via XML as with a . Use setLayoutDescription() in code to apply them. Switch states by calling setState(state_id) 10. MotionLayout - Takes animation among ConstraintSet to another level - KeyFrames: distort animation paths - KeyCycles - Motion Editor : Create, Edit animation in Design View

finally some great support....writing this by hand was such a pain!

So much awesome stuff. Can't wait to try it out!

Awesome work, thanks for your hard work and looking forward to try it!

Great work guys!!

Wow, fantastic!

Motion Design Tool looks awesome!

Motion editor looks great! Looking for a release date!

This is really pretty amazing.

ConstraintLayout is the best feature for building UI and animations :)

great tools!!

How can I set a "tools:image" or "tools:backgroud" to a normal Layout or view (not recyclerView)? In our app, these are also dynamic and setted by databinding.

It reminds me Flash... finally we can edit some cool animations easily! Bravo!

Pretty nifty

I wonder if this will work with transitions. Like viewpager transitions and fragment and activity transitions.

Useful!

It's really hard to understand the speaker's talk about. But this is AWESOME!!!)))

very powerful

Awesome motion layout editor! Is there any plan to have an editor to create all the animation in Android?

Android Studio came a long way nice

Damn with these cool tools, there needs to a book dedicated to constraint layout 2.0 lol

Is there a sample code that illustrates the usage of all these APIs?

Where can I find all of this source code? 😁

Waiting for the day when the layout editor is released as a separate app, about time now.

What can I do like 33:13 animation? Please tell me keyword

It is so frustrating not being able to use all this preview tools just because constant issues with Android Studio not being able to display layout preview.

Awesome tools! What about performance improvement on Android Studio? Its performance on macOS or Windows is garbage, I have to restart the AS at least 4 times a day.

oh John Hoford is here since io 16

Constraint layout was causing me too laggy scrolling when I was using it as a layout of item of recycler view some time ago, how about now, is it fixed?

Problem i have with the layout editor ive had a chance to use is it will often just set fixed dp sizes that i then have to fix manually.. maybe thats the old one i dunno. But its annoying.

The few days are long over :P When can we try it

Where is Helper/Layer/Decorate Example ?

We left many items that doesn't mean we don't know that. We left because we try to shortcut layout. We will add some items in the middle but that will not cause any harm to the base layout. We also left lot of things unexplained, it is because people may asked us for an explanation. We have explanations. We are not depending on anyone for anything for sure. Submit your own solution, so that other may judge us when we complete. AND, If you want to resists us, welcome. For sure we will handle you even if it worse for you. And, We assure you, "HUMANITY FIRST" is my philosophy.

Now Android Studio begins on the path of Visual Studio with these features like Handling motions, Adding Keyframes & Path editing :)

could you help me

Common CL team👌CL team never share the tech talks code like you always do! I tired of of searching all the 2017 CL talks codes hopefully it doesn't continues to 2018!😢 #talkswithoutcodeshare

Wow, after 27 version of API, they finally realize that a layout with relative dimension can be useful with multiple sceen size. That Android SDK is a joke.

Does it finally work? No, I won't try myself.....pretty disgusted with this, 2 years and still not stable...

"it's awesome because it works with your custom views" never heard such a big lie

这个主讲人中哪里人，口音好奇怪

talk is cheap. show me the code.

why do american people clap and whooooo?? ROTFL

Thanks for making android more faster..& Less versatile....With no user experience.... ANDROID Oreo cheater....you don't need to optimize things...like the world is doing....You need expand....To get the full effecieny of hardware...No more android fan

MS Powerpoint 2003 called, wants its animations back. Why are these guys so lazy, every animation demo in this google IO is an eye and brain soar. Loved the new features though.
