Android 如何在选项卡式活动片段中制作视频的recyclerview（使用Youtube API）？

video_template.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <FrameLayout
        android:name="com.google.android.youtube.player.YouTubePlayerSupportFragment"
        android:id="@+id/youtubePlayerViewer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="10dp"
        android:background="@color/colorAccent"/>

</LinearLayout>

我在网上搜索时看到的所有示例都是在activity中制作的，而不是在recyclerview的fragment中制作的。

而是制作一个Thumbnail的recycler视图。您能告诉我们到目前为止您一直在尝试做什么吗？请阅读。@Dima Kizhevin添加了我的代码和我正在尝试做的图片do@2Dee好的。非常感谢。
