Motionlayout with recyclerView is Shaky - android-motionlayout

Question

I used a recycler view in my motion-layout with a handle which is an ImageView.But the first time you want to swipe it up it shakes and goes down and up and doesn't come up.
I tried to play with the attributes but nothing worked.
layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Using the following files you can regenerate the problem.Thanks for reading.Any help would be appreciated.

Answer 1

finally fixed this bug at androidx.constraintlayout:constraintlayout 2.0.0-beta4

Answer 2

I was facing a similar issue while using MotionLayout to collapse the header. The swipe performance was terrible. So I read #8KCreativeCommons comment saying that this may be caused by the change in the recyclerview size.
Setting a fixed recyclerview height instead of the 0dp(match constraint) improved the swipe performance:
private void setRecyclerViewHeight() {
DisplayMetrics displayMetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
int height = displayMetrics.heightPixels;
mRecyclerView.getLayoutParams().height = height;
}
In your case, you would have to set a fixed size to your relative layout #+id/testId.
It would also be necessary to remove the layout_constraintBottom_toBottomOf="parent"
