我这样做是否正确，我试图有一个没有相对进展的嵌套片段。第一个 onCreateView 包含它的视图，但在 onCreateView 中，我实例化了一个新类，该类扩展了一个片段，并且还有自己的 onCreateView 和 xml。我现在遇到错误。我只是想VideoPlayerFragment在第一个主视图中显示。希望了解更多。

public static class DemoObjectFragment extends Fragment {

    public static final String ARG_OBJECT = "object";

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.load_main_menu_activity, container, false);
        //Bundle args = getArguments();

       Fragment videoFragment = new VideoPlayerFragment();
        FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
        transaction.add(R.id.testLayout, videoFragment).commit();
       //((TextView) rootView.findViewById(android.R.id.text1)).setText(
             //   Integer.toString(args.getInt(ARG_OBJECT)));
        return rootView;
    }
}

视频播放器片段

公共类 VideoPlayerFragment 扩展片段 {

  public static final String ARG_OBJECT = "object";

  @Override
  public View onCreateView(LayoutInflater inflater, ViewGroup container,
          Bundle savedInstanceState) {
      View rootView = inflater.inflate(R.id.testLayout, container, false);
      Bundle args = getArguments();
     //((TextView) rootView.findViewById(android.R.id.text1)).setText(
           //   Integer.toString(args.getInt(ARG_OBJECT)));
      return rootView;
  }

}

再次感谢@Luksprog 的提示，我自己弄清楚了。因为我想要一个嵌套片段，所以我需要一个父 xml 来在下面添加这个代码。此代码使我能够在片段中添加另一个片段。

<FrameLayout 

            android:id="@+id/fragg"
            android:layout_weight="2"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
