Answer 1

You have to import the Material Components Library provided by Google.

Material Components for Android is a drop-in replacement for Android's Design Support Library.

Add in your build.gradle:

implementation 'com.google.android.material:material:x.x.x'

Then use the class com.google.android.material.bottomsheet.BottomSheetBehavior.

In your layout you can use the attribute:

    app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior"
    ..>

or

app:layout_behavior="@string/bottom_sheet_behavior"
