如何在列表 exoplayer 中自动播放下一个视频 android

Question

我正在 android 工作室创建电影流媒体应用程序，我使用过 recyclerview 和 exoplayer。一切都很完美，最后一点就是剧集创作。我想在视频中添加剧集并在当前视频完成后自动播放它们，就像 youtube 播放器一样。我正在添加我的 json 文件，主要 activity 视频播放器 activity 以供参考。

我知道的是我可以在电影 activity 中创建另一个回收器（我会在 recyclerview 中显示我所有的剧集列表）

我需要为这个剧集列表创建一个模型和新的适配器文件，我想我必须为此创建单独的 JSon 数据，因为它与 rest

不同且特定

主要Activity。 java 计划

Answer 1

按照以下步骤非常简单:-

1]将您的所有视频添加到列表并将该列表设置为您的 exo 播放器对象，如下所示

    for (i in videoList.indices){
        var songPath:String = videoList.get(i)
        val item: MediaItem = MediaItem.fromUri(songPath)
