android - 无法在 xamarin MVVMCROSS 中从 android.support.v4.app.Fragment 转换为 android.app.Fragment

Question

嘿，在 android(Xamarin) 中，我正在尝试在操作栏中添加选项卡，我已经完成了，但是当我使用切换按钮时，会显示此错误

“FragmentTransaction”是“Android.App.FragmentTransaction”和“Android.Support.V4.App.FragmentTransaction”之间的模糊引用

这是我的代码

protected override void OnCreate(Bundle bundle)
    {

        DrawerLayout mDrawerLayout;

        base.OnCreate(bundle);

        // Set our view from the "main" layout resource
        SetContentView(Resource.Layout.Main);

        mDrawerLayout = FindViewById<DrawerLayout>(Resource.Id.drawer_layout);

        mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, Resource.Drawable.drawer, Resource.String.open_drawer, Resource.String.close_drawer); 


        FragmentTransaction transaction = FragmentManager.BeginTransaction();
        SlidingTabsFragment fragment = new SlidingTabsFragment();
        transaction.Replace(Resource.Id.sample_content_fragment, fragment);
        transaction.Commit();

        mDrawerLayout.SetDrawerListener(mDrawerToggle);
        ActionBar.SetDisplayHomeAsUpEnabled(true);
        ActionBar.SetHomeButtonEnabled(true);

    }

使用 Android.App.FragmentTransaction transaction = FragmentManager.BeginTransaction();
