Java 在操作工具栏中使用DrumerMenu的片段

问题在于，我的主要活动是由抽屉活动组成的，当我给出抽屉活动的一些选项时，我必须传递给片段，问题在于，当我传递给片段时，我失去了从片段抽屉打开菜单的选项

`

这是java代码的主要活动

这是我想要实现抽屉的片段代码

public class Fragmen1 extends Fragment {

   Button HBoton;
   Button GBoton;
   Button SCTBoton ;
   Button RGboton ;
   Button CPBoton ;
   Button ARBoton;


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate(R.layout.fragment_fragmen1, container, false);


        HBoton = (Button) view.findViewById(R.id.HipotenusaBoton);
        HBoton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {


                Intent HBoton = new Intent(getActivity(), Hipotenusa.class);
                startActivity(HBoton);
            }
        });



         GBoton= (Button) view.findViewById(R.id.button3);
        GBoton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {


                Intent GBoton = new Intent(getActivity(), Grados_Radianes.class);
                startActivity(GBoton);
            }
        });



        SCTBoton = (Button) view.findViewById(R.id.SCTboton);
        SCTBoton.setOnClickListener(new  View.OnClickListener() {


            @Override
            public  void  onClick (View v ){



                Intent SCTBoton = new Intent(getActivity(), SenoCosenoTangente.class);
                startActivity(SCTBoton);
            }
        });

        RGboton = (Button) view.findViewById(R.id.button6);
        RGboton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                Intent RGboton = new Intent(getActivity(),RadianesGrados.class);
                startActivity(RGboton);
            }
        });


        CPBoton = (Button) view.findViewById(R.id.CAPbutton);
        CPBoton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

                Intent CPBoton = new Intent( getActivity(),CordenadasRectagularesPolares.class);
                startActivity(CPBoton);
            }
        });

        ARBoton = (Button) view.findViewById(R.id.arboton);
        ARBoton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                Intent ARBoton = new Intent( getActivity(),AnguloReferencia.class);
                startActivity(ARBoton);

            }
        });

        return  view;

    }

}

看，你需要有一个抽屉供所有活动共享，所以请查看并查看答案中的链接。我使用的抽屉菜单有默认的android studioIt是相同的代码，要么你自己做，要么android Studio为你生成。

public class Fragmen1 extends Fragment {

   Button HBoton;
   Button GBoton;
   Button SCTBoton ;
   Button RGboton ;

        View view = inflater.inflate(R.layout.fragment_fragmen1, container, false);
