无法使用导航情节提要板在片段中添加按钮以从一个片段跳转到另一个片段

Question

I am trying to add a button in a fragment page to jump from one fragment to another fragment using the method of the navigation storyboard of android studio. However, in the Mainfragment.java, my button id cannot be resolved, it cannot recognize my button id and I don't know why. Please help!

  public MainFragment() {

        // Required empty public constructor
    }


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


    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        Button goToBtn = (Button) this.findViewById(R.id.goToBtn);
        goToBtn.setOnClickListener(Navigation.createNavigateOnClickListener(R.id.toAccount, null));


    }
    }

For the above codes in Mainfragment.java , the findViewById is red.

Answer 1

change below line

Button goToBtn = (Button) this.findViewById(R.id.goToBtn);

With

Button goToBtn = (Button) view.findViewById(R.id.goToBtn);
