在我的活动中，我有一个viewPager，例如3页。
在所有这些页面中，我都有一个带有不同ID视频的YouTubePlayer。
问题在于所有YouTubePlayer组件同时具有相同的视频。
具体来说：
显示第一页时，YouTubePlayer会显示第一部视频，因此一切正常。
当我尝试滚动到第二页时，可以看到第二YouTubePlayer播放相同的视频。
当第二页完全显示时（滚动后），在视图寻呼机后面准备第三页。因此，在第3页上，将第3个ID视频设置为YouTubePlayer组件。此时，当前显示的第二页将自动切换到第三视频。
就像YouTubePlayer的实例对于所有页面都是单个的一样。
但是在每个页面上都会正确调用新的FragmentYouTubePlayer（）。
我不明白问题出在哪里。
最后，我想知道是否可以同时使用多个YouTubePlayer组件（在viewpager中）？
谢谢你的帮助。

我不记得到底是哪里出了问题，但是是的，我解决了我的问题。因此，如果可以帮助您，请执行以下代码：
在我的主要活动中，使用PagerAdapter：
private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter {
public ScreenSlidePagerAdapter(android.support.v4.app.FragmentManager fm) {
super(fm);
}
@Override
public android.support.v4.app.Fragment getItem(int position) {
fragmentYouTubeContent = FragmentYouTubeContent.create(position);
return fragmentYouTubeContent;
}
@Override
public int getCount() {
int nb = 3;
return nb;
}
}
我的FragmentYouTubeContent.class
