适配器位置不正确

Question

我有一个custom adapter，其中有混合数据，数据列表中有视频和图像URL，并根据数据类型将它们绑定到不同的视图持有者。我正在使用SnapHelper使其像滑块一样。我在水平列表中显示youtube video和图像。当我向左滑动适配器时，适配器将提供正确的视图位置；向右滑动时，适配器将为我提供错误的随机位置，因此我的YouTube播放器在达到其视图类型之前会崩溃。向左打印位置为0 1 2 3 4 5，向右打印位置为6 2 3 1然后崩溃，RecyclerView中有一个视频，其他是图像。向后滑动时应用崩溃。找不到片段YouTubePlayerFragment的ID 0x7f0901b0（com.array151.mypu：id / youtube_holder）的视图，出现此错误。
