Answer 1

The BottomSheetDialogFragment is provided by the Material Components Library:

• Official Doc
• Source code
• Demo code

Relevant part of the doc about the usage:

• Subclass BottomSheetDialogFragment
• Override the onCreateView method.
• Use one of the two versions of show to display the dialog. Notice BottomSheetDialogFragment is a subclass of AppCompatFragment, which means you need to use Activity.getSupportFragmentManager().

Note: Don't call setOnCancelListener or setOnDismissListener on a BottomSheetDialogFragment, instead you can override onCancel(DialogInterface) or onDismiss(DialogInterface) if necessary.
