描述

When using both a Snackbar (set to Snackbar.LENGTH_INDEFINITE in my testing) and a FloatingActionButton together, the swipe to dismiss behaviour on the Snackbar tries to snap back to the start of the screen throughout the swipe causing a graphical glitch. The Snackbar dismisses without this graphical glitch if a FAB is not present in the Coordinator Layout.

The FAB also seems not to react to the Snackbar swipe to dismiss events as it stays where it is after the dismiss, instead of dropping down to just above the Bottom Navigation.

研究方向
Investigate the interaction between Snackbar with LENGTH INDEFINITE and FloatingActionButton within CoordinatorLayout. Look at the Snackbar's swipe to dismiss behavior, specifically how it snaps during swipe when a FAB is present. Check the SwipeDismissBehavior class and the library's implementation of CoordinatorLayout.Behavior for FAB. The issue also mentions the FAB not moving after dismiss, so examine the animate offset logic for FAB. There are 10 comments that may contain additional details. No linked PRs.
