How can I expand the BottomSheet so that when it appears below the rest of the screen BottomSheet and when I click on it, the panel will slide back like in AlertDialog ?

    You need to inherit from BottomSheetDialogFragment

     public class TutsPlusBottomSheetDialogFragment extends BottomSheetDialogFragment { private BottomSheetBehavior.BottomSheetCallback mBottomSheetBehaviorCallback = new BottomSheetBehavior.BottomSheetCallback() { @Override public void onStateChanged(@NonNull View bottomSheet, int newState) { if (newState == BottomSheetBehavior.STATE_HIDDEN) { dismiss(); } } @Override public void onSlide(@NonNull View bottomSheet, float slideOffset) { } }; @Override public void setupDialog(Dialog dialog, int style) { super.setupDialog(dialog, style); View contentView = View.inflate(getContext(), R.layout.fragment_bottom_sheet, null); dialog.setContentView(contentView); CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) ((View) contentView.getParent()).getLayoutParams(); CoordinatorLayout.Behavior behavior = params.getBehavior(); if( behavior != null && behavior instanceof BottomSheetBehavior ) { ((BottomSheetBehavior) behavior).setBottomSheetCallback(mBottomSheetBehaviorCallback); } } } 
     BottomSheetDialogFragment bottomSheetDialogFragment = new TutsPlusBottomSheetDialogFragment(); bottomSheetDialogFragment.show(getSupportFragmentManager(), bottomSheetDialogFragment.getTag());
