我创建了一个自定义 DialogFragment，它加载了一个名为 student_info_main_container 的自定义布局。这个布局包含一个 ViewFlipper，我加载了两个额外的布局。问题是 ViewFlipper 没有显示在我的 DialogFragment 中，但 student_info_main_container 布局的其余部分确实显示了。我的大部分工作都是在 OnCreateView 中完成的。任何帮助，将不胜感激。

public class StudentInfoUIViewController : DialogFragment, IJoinClassView
    {
        private ViewFlipper studentInfoContentFlipper;

        public static StudentInfoUIViewController NewInstance() 
        {
            StudentInfoUIViewController frag = new StudentInfoUIViewController();     
            frag.SetStyle(DialogFragmentStyle.NoTitle, 0);

            return frag;
        }

        public override void OnAttach(Activity activity)
        {
            base.OnAttach(activity);
            Log.Debug("StudentInfoUIViewController", "OnAttach Called.");
        }

        //This is called to create the view and initialize the UI.  The UI isn't made visible until OnStart is called.
        public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
        {
            Dialog.Window.SetGravity(GravityFlags.Top);

            //Inflate and set the main layout for this DialogFragment
            View mainView = inflater.Inflate(Resource.Layout.student_info_main_container, container, true);

            //Find the ViewFlipper in the mainView
            studentInfoContentFlipper = Activity.FindViewById<ViewFlipper>(Resource.Id.studentInfoMainContainer_viewFlipper_studentInfoContent);

            //Inflate the layouts that are going to be added to the studentInfoContentFlipper ViewFlipper
            View joinSelectionView = inflater.Inflate(Resource.Layout.student_info_join_selection, null);
            View test = inflater.Inflate(Resource.Layout.test, null);

            //Add the above views to the flipper.
            studentInfoContentFlipper.AddView(joinSelectionView, 0);
            studentInfoContentFlipper.AddView(test, 1);


            Log.Debug("StudentInfoUIViewController", "OnCreateView Called.");

            return mainView;
        }

        public override void OnStart()
        {
            base.OnStart();
            //UI is visible
            Log.Debug("StudentInfoUIViewController", "OnStart Called.");

        }               

    }

不要ViewFlipper在. Activity_ _ _ Fragment也不要使用参数设置为的Inflate()方法，因为这会将膨胀的视图添加到容器中，这将在返回后由系统自动再次完成。booleantrueonCreateView
