Question

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

然而它会抛出错误：

无法访问外部类型的非静态成员

'Android.Support.V4.App.Fragment'通过嵌套类型

“*******。Fragments.Dashboard.ViewAdapter`

我做错了什么？

代码：

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;
}

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

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

无法通过嵌套类型X
