如何喜欢/不喜欢和订阅 Android 应用中的 YouTube 视频

Question

我正在尝试创建一个 YouTube 视频 Android 应用程序。目前播放视频和获取播放列表没有问题，因为有此示例。但我无法找到任何好的参考 like/unlike并在 YouTube 中订阅活动。

那么如何从安卓应用中点赞/取消点赞和订阅 YouTube 视频？

我们将不胜感激。

Answer 1

我认为您无法在自己的应用程序中执行此操作。

您必须通过 YouTube 应用将应用程序的用户重定向到他想要订阅的频道。

您可以通过 YouTube API 使用此方法：createChannelIntent (link)。从那里，您的用户将能够订阅该频道，因为它将在 YouTube 应用中打开。

确保在 (link) 之前安装了 YouTube 应用！ :)

希望对你有帮助！

Answer 2

您需要使用 YouTube 数据 API。 Here 你可以阅读如何喜欢/不喜欢视频。

也许你可以使用这个代码：

// Sample Java code for user authorization

            YouTube.Videos.Rate videosRateRequest = youtube.videos().rate(parameters.get("id").toString(), parameters.get("rating").toString());

        } catch (GoogleJsonResponseException e) {
