If a button has a WRAP_CONTENT width and after its text is updated but its size does not change, the icon position won't be updated because at the moment when onTextChanged() is called, getLayout() will return null and a new layout to display text will only be recreated in the next onMeasure() call.
To fix this issue, the change moves updateIconPosition() from onSizeChanged() to onLayout(), which will always be called after onMeasure() or onSizeChanged() is called, and thus covers both of the cases after the text is updated (the button changes its size or not.)
Note: we still need to keep the updateIconPosition() call in onTextChanged(), to cover the case that the button has a fixed width, in which updating text won't trigger remeasuring of the button.

This CL pulls out the checkable group logic to a standalone class, which can be shared by different UX components. It also makes chip groups support multiple selection better with introducing a new listener based on the multiple selection and deprecates the old listener which only supports single selection.

LayerDrawable has this bug that if any of the provided drawables are null during creation, it crashes. The fix is only available on Q+. Fixes this by providing a dummy drawable when we find checked icon is null.

Fixes the logic in NavigationBarMenuView.restoreBadgeDrawables(), which may override the newly created badges with the restored drawables incorrectly. Also adds a safe guard that removes the previously attached badges if any, before attaching a new badge.

Add an expanding animation for the focused underline that's triggered when the edit text gains focus. The line mask animation is built to calculate its bounds based on the hint CollapsingTextHelper's expansion fraction, so it seamlessly follows that animation.

We set ?attr/colorControlHighlight as scroll indicators' background attribute. However, on older platforms this will crash the app due to Android expects a drawable or a plain color for the background attribute.
Changes the view to TextView so it will be rendered as MaterialTextView, which supports app:backgroundTint with CSLs. Also changes the base background color to #1F000000 and the tint color to ?attr/colorForeground, which are aligned with what framework's alert dialog implementation is doing.

When scroll range changes, the current scroll position may not make sense anymore. Therefore we need to save the scroll state and restore it after the scroll range is invalidated. This change reuses and refactors the existing saving instance state logic to support this need. Also adds a flag to denote "fully expanded" state to avoid improper scroll position calculation when views are still being initialized.

This CL fixes a couple of badge state related issues. First, it prevents the badges created before restoring instance states from being overwritten by the old instance states. Second, it makes badges reload their default style settings everytime when its being recreated so if the environment has been changed, the default values will reflect the environment change.
This CL also fixes that several attributes were not correctly saved/restored or their default values were not correctly loaded.

1. Consolidates single selected ID and multiple selected IDs to a single selected
ID set.
2. Separates View states and internal checked states so we can focus and enforce
policies much easier on only internal states.

The snack bar content layout is by default horizontal, and we only change it to vertical when the action view is too wide and ellipsizes the message text. Therefore if the layout orientation is already vertical, we should just keep the layout and no need to check if the message text is multi-line again.
