片段：java.lang.IllegalArgumentException：找不到ID为0x7f0c006f的视图

我试图从一个片段移动到第二个片段。
它显示以下错误：

java.lang.IllegalArgumentException: No view found for id 0x7f0c006f (com.chinatown.wangjian.chinatownbang:id/viewpager) for fragment TwoFragment{10598077 #1 id=0x7f0c006f android:switcher:2131492975:1}

这是我的第一个片段：

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

        getActivity().setContentView(R.layout.activity_scrolling);
        Toolbar toolbar = (Toolbar) getActivity().findViewById(R.id.toolbar);
        ((AppCompatActivity) getActivity()).setSupportActionBar(toolbar);

        FloatingActionButton fab = (FloatingActionButton) getActivity().findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });



        return v;

我的第二个片段是这样的：

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

我编码正确吗？

在您的代码中，似乎您正在应用2个布局。

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.activity_scrolling, container, false);
    //why setContentView?
    //getActivity().setContentView(R.layout.activity_scrolling);
    Toolbar toolbar = (Toolbar) getActivity().findViewById(R.id.toolbar);
    ((AppCompatActivity) getActivity()).setSupportActionBar(toolbar);

    FloatingActionButton fab = (FloatingActionButton) getActivity().findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });



    return v;
