[FIXED] Bottomsheet takes full screen

Issue

I am trying not to have a BottomSheet that populates whole screen but to leave some space above when it expanded. Here is my code which onExpand populates whole screen.

bottomSheetBehavior = BottomSheetBehavior.from(bottomLayout);
        bottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);

        bottomSheetBehavior.setBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
            @Override
            public void onStateChanged(@NonNull View bottomSheet, int newState) {
                switch (newState) {
                    case BottomSheetBehavior.STATE_DRAGGING:
                        Log.i("BottomSheetCallback", "BottomSheetBehavior.STATE_DRAGGING");
                        break;
                    case BottomSheetBehavior.STATE_SETTLING:
                        Log.i("BottomSheetCallback", "BottomSheetBehavior.STATE_SETTLING");
                        break;
                    case BottomSheetBehavior.STATE_EXPANDED:
                        Log.i("BottomSheetCallback", "BottomSheetBehavior.STATE_EXPANDED");
                        break;
                    case BottomSheetBehavior.STATE_COLLAPSED:
                        Log.i("BottomSheetCallback", "BottomSheetBehavior.STATE_COLLAPSED");
                        break;
                    case BottomSheetBehavior.STATE_HIDDEN:
                        Log.i("BottomSheetCallback", "BottomSheetBehavior.STATE_HIDDEN");
                        break;

                }
            }

            @Override
            public void onSlide(@NonNull View bottomSheet, float slideOffset) {
                Log.i("BottomSheetCallback", "slideOffset: " + slideOffset);
                boolean drawer = getSupportFragmentManager().getBackStackEntryCount() == 0;
                ObjectAnimator.ofFloat(drawerArrow, "progress", drawer ? 0 : 1).start();
            }
        });


        bottomLayout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Log.v(TAG, "ONCLickListner");

                if (bottomSheetBehavior.getState() == BottomSheetBehavior.STATE_COLLAPSED) {
                    Log.v(TAG,"state expand");
                    bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
                } else {
                    Log.v(TAG,"state collapse");
                    bottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
                }

            }
        });

Can you please address my problem and suggest a way of making bottomsheet not to take whole screen but for leaving some space above when expanded. Thanks

Solution

A simple trick has done it. I was not able to prevent bottom sheet from having full screen for now, so i had a view which is transparent of my required size, and by adding it to the bottomSheetLayout resolved my issue

<View
    android:layout_width="match_parent"
    android:id="@+id/spaccer"
    android:layout_height="28dp"
    android:background="@android:color/transparent"
    android:alpha="0.6"/>
