我正在使用YouTube数据API访问视频。我成功地在ListView上显示缩略图图像。当我启动应用程序，并单击列表项目之一装载视频应该播放的容器上。我得到了问题，当我点击下一个缩略图图像，然后下一个视频不显示。我检查通过索引日志，位置改变，但视频不加载。我不不知道我在哪里做错了？Youtube视频不被停止点击时HorizontalListView项目
这是和我一样的问题，但没有能够解决这个看How to refresh Youtube Player View onItemClickListener() in a ListView

列表项指数都在日志中显示变化，但运行的视频没有停止，并开始新的视频当另一个列表项点击Video.How可以在此问题得到解决？
只是一分钟我会执行它 – Ghimire
