Use Coordinate layout instead of constraint layout, and define bottomsheet layout in xml like below

In Java Class Use like this.

    private BottomSheetBehavior mBottomSheetBehavior;
    private View bottomSheet;
    private isBottomSheetExpand = false;
    ...
    btn1.setOnClickListner(new View.OncliView.OnClickListener(){
    @Override
        public void onClick(View v) {
            if(isBottomSheetExpand){
                openBottomSheet();
            }else{
                closeBottomSheet();
            }
        }
    });
    ...
    public void closeBottomSheet() {
       if (mBottomSheetBehavior.getState() == BottomSheetBehavior.STATE_EXPANDED) {
            mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
            isBottomSheetExpand = false;
        }
    }

    public void openBottomSheet() {
        if (mBottomSheetBehavior.getState() != BottomSheetBehavior.STATE_EXPANDED) {
            mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
            isBottomSheetExpand = true;
        }
    }
