Question

我正在尝试执行以下代码：

FrameLayout fragmentContainer = FindViewById<FrameLayout>(Resource.Id.fragmentContainer);
fragmentContainer.RemoveAllViews();
fragmentMain.view = fragmentMain.LayoutInflater.Inflate(Resource.Layout.MainLayoutPortrait, null, false);
fragmentContainer.AddView(fragmentMain.view);

但是当我到达我的代码的3d行并尝试获取fragmentMain.LayoutInflater：

fragmentMain.view = fragmentMain.LayoutInflater.Inflate(Resource.Layout.MainLayoutPortrait, null, false);

程序失败并出现错误：

onGetLayoutInflater() cannot be executed until the Fragment is attached to the FragmentManager.

Answer 1

尝试这样做：

    LayoutInflater inflater = (LayoutInflater)this.GetSystemService(Context.LayoutInflaterService);
        view = inflater.Inflate(Resource.Layout.Buttons, layout);

如果你在片段使用活动上下文中获取GetSystemService

古德勒克！
