java - 如何忽略或禁用线性布局

Question

首先，我想做一个底部弹出，但我不知道如何忽略布局。我只想显示灰色布局。我正在尝试使其对白色布局透明，但它不起作用。我想我必须使用一些代码来忽略或删除它。我使用不可见的，这将使所有布局不可见。

这是我制作弹出窗口的代码

public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.fragment_account, container, false);

    backbutton1 = (ImageView) rootView.findViewById(R.id.backbutton1);
    btnprofile = (Button) rootView.findViewById(R.id.btnprofile);
    backbutton1.setOnClickListener(onClickListener);
    btnprofile.setOnClickListener(onClickListener);

    return  rootView;

}

private View.OnClickListener onClickListener = new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        if(view == backbutton1) {
            startActivity(new Intent(getActivity().getApplicationContext(), sidemenu.class));
            getActivity().overridePendingTransition(R.anim.slide_in_left, R.anim.slide_out_right);
        }if(view == btnprofile){

            Bottom_sheet bottom_sheet = new Bottom_sheet();
            bottom_sheet.show(getFragmentManager(), "examplebottomsheet");

        }
    }
};

Bottom_Sheet 类：

   public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.popout_chooseimage, container, false);

    Button btnCancel = (Button) view.findViewById(R.id.buttonCancel);
    Button btnRemove = (Button) view.findViewById(R.id.buttonRemove);
    Button btnTake = (Button) view.findViewById(R.id.buttonTake);
    Button btnLibrary = (Button) view.findViewById(R.id.buttonLibrary);

    LinearLayout linear = (LinearLayout) view.findViewById(R.id.bottom_layout);
    linear.setBackgroundResource(0);

    btnCancel.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dismiss();
        }
    });

    return view;
}

布局：
