Motionlayout: WARNING could not find view id -1
问题 My problem is, that I constantly get the warning W/MotionLayout: WARNING could not find view id -1 . Because of this, my MotionLayout is really laggy and nearly jumps from the expanded state to the collapsed state . After waiting a couple of seconds, the animation starts getting better (no jumping / laggs anymore), but the warning remains.
