title: Bottomsheet takes full screen
body: <p>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.</p>
  
  <pre><code>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);
                  }
  
              }
          });

  <p>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</p>
