c# – 无法通过嵌套类型X访问外部类型X的非静态成员

我想调用Main Activity中的方法来调用一个新的Fragment
    ((FragmentActivity)Activity).ShowFragment(new SmokeSensor());

但它会抛出错误：

Cannot access a non-static member of outer type

‘Android.Support.V4.App.Fragment’ via nested type

‘*******.Fragments.Dashboard.ViewAdapter`

我究竟做错了什么？

码：

public void ShowFragment(SupportFragment fragment) {
    var transaction = SupportFragmentManager.BeginTransaction();
    connectionStatus.Visibility = ViewStates.Gone;

    if (!ConnectionDetector.IsConnected(this)) {
        connectionStatus.Visibility = ViewStates.Visible;

        transaction.Detach(currentFragment);
        transaction.Commit();
        drawerLayout.CloseDrawer(leftDrawer);

        return;
    }

    if (fragment == currentFragment) {
        transaction.Detach(currentFragment);
        transaction.Attach(currentFragment);
        transaction.Commit();
        drawerLayout.CloseDrawer(leftDrawer);

        return;
    }

    transaction.SetCustomAnimations(Resource.Animation.slide_in,Resource.Animation.slide_out);
    transaction.Replace(Resource.Id.fragment_container,fragment);
    transaction.Commit();
    drawerLayout.CloseDrawer(leftDrawer);
    currentFragment = fragment;
}

解决方法

为什么你的“Android.Support.V4.App.Fragment”在*******中只能是静态的.Fragments.Dashboard.ViewAdapter？

看到那个cannot-access-a-non-static-member-of-outer-type
或this
