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
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.
Try to increase default values of memory sizes for JVM in which Android Studio runs: android-studio/bin/studio64.exe.vmoptions -Xms1024m -Xmx4096m -XX:ReservedCodeCacheSize=1024m It helps for me to prevent restarting Android Studio several times a day
Eugene, thanks for the tip. I tried it here, but it didn't work. I've been working in AS for 2 hours today (using your tip) and it's already consuming 8.2GB of RAM, and growing...
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.
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.
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.
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.
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?

Andrew Grosner Awesome, I should try it out again then :)
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.
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
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.
That motion design tool in Android Studio is dope. Can't wait to try it out!
Do you know if they have any release dates yet?
I will cover everything in my ConstraintLayout tutorial as soon as the stable releases are out
Please make some tutorial of Motion Editor! PLEASE!
finally some great support....writing this by hand was such a pain!

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
ConstraintLayout is the best feature for building UI and animations :)
Motion editor looks great! Looking for a release date!
It's really hard to understand the speaker's talk about. But this is AWESOME!!!)))
Great work guys!!
It reminds me Flash... finally we can edit some cool animations easily! Bravo!
Motion Design Tool looks awesome!
So much awesome stuff. Can't wait to try it out!
Android Studio came a long way nice
Damn with these cool tools, there needs to a book dedicated to constraint layout 2.0 lol
Awesome work, thanks for your hard work and looking forward to try it!
Is there a sample code that illustrates the usage of all these APIs?
This is really pretty amazing.
Awesome motion layout editor! Is there any plan to have an editor to create all the animation in Android?
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.
me too! I think there is a memory leak issue
Try to increase default values of memory sizes for JVM in which Android Studio runs:
android-studio/bin/studio64.exe.vmoptions
-Xms1024m
-Xmx4096m
-XX:ReservedCodeCacheSize=1024m

dafuq!!! just Windows OS takes 2-4 gb of memory for working :S
Game4rt Did that already. Didn't work
Useful!
I wonder if this will work with transitions. Like viewpager transitions and fragment and activity transitions.
What can I do like 33:13 animation?
Please tell me keyword
The few days are long over :P When can we try it
Pretty nifty
Waiting for the day when the layout editor is released as a separate app, about time now.
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.
oh John Hoford is here since io 16

Where can I find all of this source code? 😁
great tools!!
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 fixed dp sizes is really annoying.
Where is Helper/Layer/Decorate Example ?
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?
Andrew Grosner Awesome, I should try it out again then :)
Now Android Studio begins on the path of Visual Studio with these features like Handling motions, Adding Keyframes & Path editing :)
very powerful

Check out my GitHub repo on ConstraintLayout Animations.
could you help me
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

why do american people clap and whooooo?? ROTFL

talk is cheap. show me the code.
