Xamarin开发：TabbedPage能否实现可展开置顶音频播放器？

我正在开发一款支持Android和iOS的电台音乐收听应用，当前采用底部菜单的TabbedPage设计。已在MainActivity中创建了一个始终悬浮于所有Tab页面上方的LinearLayout音频播放器视图，希望实现该播放器向上展开与收起的功能（参考效果：）。

核心疑问：TabbedPage是否支持该功能，还是需要更换架构？也考虑过使用不同的LinearLayout或RelativeLayout，附上相关代码如下：

MainActivity代码 #

ViewGroup contentView = FindViewById<ViewGroup>(Android.Resource.Id.Content);
LinearLayout view = new LinearLayout(this);
view.Orientation = Android.Widget.Orientation.Horizontal;
view.SetBackgroundColor(Android.Graphics.Color.Blue);
view.Background = getDrawableWithRadius();
FrameLayout.LayoutParams parameter = new FrameLayout.LayoutParams((Device.Idiom == TargetIdiom.Tablet ? 60 : LinearLayout.LayoutParams.MatchParent), (Device.Idiom == TargetIdiom.Tablet ? 110 : 160));
parameter.Gravity = GravityFlags.Bottom | GravityFlags.Left;
parameter.BottomMargin = 220;
view.LayoutParameters = parameter;

btnPushPlay = new Android.Widget.ImageButton(this);
btnPushPlay.Click += BtnPushPlay_Click;
btnPushPlay.SetBackgroundColor(Android.Graphics.Color.Transparent);
btnPushPlay.SetImageResource(Resource.Drawable.media_play_green);
view.AddView(btnPushPlay);
lblSong = new TextView(this);
lblSong.TextSize = 18;
lblSong.SetPadding(10, 35, 0, 0);
lblSong.SetTextColor(Android.Graphics.Color.White);
lblSong.Text = "Luister live!";
view.AddView(lblSong);
contentView.AddView(view);

MainPage.xaml代码 #

<?xml version="1.0" encoding="utf-8" ?>
<TabbedPage xmlns="http://xamarin.com/schemas/2014/forms"

        android:TabbedPage.ToolbarPlacement="Bottom"
        BarBackgroundColor="#000000"
        BarTextColor="White"
        BackgroundColor="Black"
        x:Class="Kickit_Radio.MainPage"
        NavigationPage.HasNavigationBar="False"
        NavigationPage.HasBackButton="True" SelectedTabColor="Green" UnselectedTabColor="#3184ca">

</TabbedPage>
