Android 点击按钮时，底板不显示

我目前正在使用coordinatorLayout实现底部表单内部和活动。点击“显示扫描仪结果按钮”时，底部表单应向上滑动。我已经实现了所有必要的代码，但当按下按钮时，什么也没有发生

以下是主要活动代码

public class Dashboard extends AppCompatActivity{

   private LinearLayout mBottomSheet;
    private BottomSheetBehavior mBottomSheetBehavior;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_dashboard);


        mBottomSheet = findViewById(R.id.bottomSheetContainer);

        mBottomSheetBehavior = BottomSheetBehavior.from(mBottomSheet);


       Button buttonShow = findViewById(R.id.buttonShow);

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

                if(mBottomSheetBehavior.getState() != BottomSheetBehavior.STATE_EXPANDED){
                    mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
                } else {
                    mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
                }

            }
        });

        mBottomSheetBehavior.addBottomSheetCallback(new BottomSheetBehavior.BottomSheetCallback() {
            @Override
            public void onStateChanged(@NonNull View bottomSheet, int newState) {

            }

            @Override
            public void onSlide(@NonNull View bottomSheet, float slideOffset) {


            }
        });

下面是XML代码
