Motion Layout with EditText destroys animations

Question

I created a simple MotionLayout which is almost similar to a coordinator layout (animations are slightly different).
Something like this here:

Using (a couple) EditText Views within the content area breaks the MotionLayout Animations once the Keyboard was open. The animations have now a delay, the states are wrong and the UI starts to freeze a bit. Any ideas how to solve this? Link to the bug as gif

Used Versions:

com.google.android.material:material:1.2.0-alpha01
androidx.constraintlayout:constraintlayout:2.0.0-beta3

I could reproduce the behavior also in a small sample app

Sample layout.xml:

It's because of different scrolling event with/or without keyboard. For our case, we just disabling scrolling of `AppBarLayout`. — GensaGames, Nov 11 '19 at 21:33
What is the value of _windowSoftInputMode_ in your manifest? When you scroll, it looks like the focused _EditText_ is being scrolled back into view which makes sense. It is not clear what you want to happen in this scenario. You can try changing the value of _windowSoftInputMode_ to see if it helps you at all. — Cheticamp, Nov 15 '19 at 15:53
Do you mind putting your sample on github so we can help you analyze from there? — Isai Damier, Nov 16 '19 at 17:42
@IsaiDamier https://github.com/CaptMustache/views-widgets-samples I just added an EditText Field to the end of the scolllayout. Please check the "Complex Motion Samples" and play around with the Inputfield + Keyboard + Scrolling — 0xPixelfrost, Nov 20 '19 at 18:47
@GensaGames The approach here is to use only the motion layout and its animations without using the AppBarLayout. See Googles motion layout sample 17 +18 https://github.com/CaptMustache/views-widgets-samples/tree/master/ConstraintLayoutExamples/motionlayout/src/main/res/layout — 0xPixelfrost, Nov 20 '19 at 18:55
@Cheticamp I tried them all already, without success. With a coordinator layout i could use android:windowSoftInputMode="adjustResize" to fix the animation with open keyboard, but the goal here is to use only the MotionLayout — 0xPixelfrost, Nov 20 '19 at 19:00
I see you have a number of projects in that repo. Which one should I look at? — Isai Damier, Nov 20 '19 at 19:09
Its the forked one from google views-widgets-samples:https://github.com/CaptMustache/views-widgets-samples — 0xPixelfrost, Nov 21 '19 at 08:36
Nope, i went back to the default CoordinatorLayout with a AppBarLayout + CollapsibleToolbar (incl. app:layoutDescription) for the header and a NestedScrollview + layout_behavior for the content. It worked out the some way but without the bugs above — 0xPixelfrost, Apr 03 '20 at 15:07

This issue is common, wrapper the motion layout with a constraintLayout

<ConstraintLayout >

<androidx.constraintlayout.motion.widget.MotionLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layoutDescription="@xml/animation"
tools:showPaths="true">


<androidx.constraintlayout.motion.widget.MotionLayout />


<ConstraintLayout />

I consumed one of my precious points to downvote this. What on earth answer is that, with no explanation and a solution that is bad and wouldn't work anyway. MotionLayout is designed to be the parent layout, it is designed to act just like a ConstraintLayout. Creating pointless layout indentation is just bad. – M'aiq the Coder Jun 26 '20 at 12:02
Works for me. ContraintLayout is designed to be the parent layout. – IceSoul Sep 01 '20 at 16:45
