Question

我在android中使用opentok videocall库。我想要与WhatsApp相同的功能。在这个应用程序中，我的屏幕上有3个订阅者和1个发布者视图。当我们触摸任何订阅者视图时，它应该以全屏视图切换。我附加了一个屏幕，以便更好地理解。当我们触摸订户2视图时，在此屏幕中，它应该与订户1交换其视图，当我们按任何其他订户视图时，它应该与大视图的主视图交换。

屏幕二

屏幕三

我的代码在这里，我可以相互切换订阅者，但无法在主屏幕中管理它们。

Tokbox QA这里的东西。

Opentok不会为您做到这一点，因为那是您的功能。您需要捕获屏幕按下，并自行调整发布者/订阅者的画布大小。我们不会处理您希望如何在屏幕上显示订阅者。
