Answer 1

我的代码：

@Override
public View onCreateView(
        @NonNull LayoutInflater inflater, ViewGroup container, Bundle 
savedInstanceState) {
    // Inflate the layout for this fragment with the ProductGrid theme
    View view = inflater.inflate(R.layout.product_grid_fragment, container, false);
    // Set up the tool bar
    setUpToolbar(view);
    esas_btn = (Button)view.findViewById(R.id.esas_btn);
    mq = (Button)view.findViewById(R.id.mq_btn);
    sur = (Button)view.findViewById(R.id.sure_btn);
    da = (Button)view.findViewById(R.id.dua_btn);
    esas_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // Begin the transaction
                setFragment(new EsasFragment());
        }
    });        mq.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // Begin the transaction
                setFragment(new MQMaterialFragment());
        }
    });        sur.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // Begin the transaction
                setFragment(new SurelerFragment());
        }
    });        da.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // Begin the transaction
                setFragment(new DualarFragment());
        }
    });


    return view;
}

private void setFragment(Fragment fragment){
    FragmentTransaction ft = getFragmentManager().beginTransaction();
    ft.replace(R.id.content_frame, fragment, "visible_fragment");
    ft.addToBackStack(null);
    ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
   ft.commit();        toolbar.setNavigationIcon(getResources().getDrawable(R.drawable.shr_branded_menu));
}

private void setUpToolbar(View view) {
    toolbar = view.findViewById(R.id.app_bar);
    AppCompatActivity activity = (AppCompatActivity) getActivity();
    if (activity != null) {
        activity.setSupportActionBar(toolbar);
    }

    toolbar.setNavigationOnClickListener(new NavigationIconClickListener(
            getContext(),
            view.findViewById(R.id.product_grid),
            new AccelerateInterpolator(),
            getContext().getResources().getDrawable(R.drawable.bran_menu), 
    getContext().getResources().getDrawable(R.drawable.close_menu))); // Menu close icon
}
