我正在创建Android应用程序,它将在水平(横向)列表视图中显示YouTube视频,类似于屏幕截图中的应用程序。当我点击其中一个视频然后它应该播放,这是当前发生的,能够加载所有的YouTube视频以及缩略图在Android中的简单列表视图(垂直),但我无法找到到目前为止,使用该方法,我可以按照以下屏幕截图布局视图中显示的方式显示youtube播放列表中的所有视频。
如果有人知道如何在水平(风景)布局中显示我的视频列表,如附带的屏幕截图所示,那对我来说将是很有帮助的。
请访问链接以查看屏幕截图:https://sc-cdn.scaleengine.net/i/954e89ab4d5fef83bb19009107d71c60.png
谢谢。

你做错了。你的片段Xml应该是这样的:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<com.google.android.youtube.player.YouTubePlayerView
android:id="@+id/youtube_player"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#fff"
android:padding="5dp"
/>
</android.support.v4.view.ViewPager>
</LinearLayout>
现在进行相应的编码并发布您的logcat以解决崩溃问题。
