我在完成活动时遇到了一个奇怪的问题。 我的应用程序中有两个活动。第一个是我的主要活动，将打开第二个活动。第二个活动是带有两个按钮的简单活动。 第一个按钮是“取消”按钮，应该取消该过程并关闭活动。因此，我在单击侦听器中将“取消”按钮称为“取消”按钮。一切都很好，并且在我测试过的所有设备上都可以正常工作。
第二个按钮再次启动另一个活动，等待它完成其工作并返回响应。得到响应后，我调用finish（）关闭第二个活动，但是这次在某些设备上不起作用。我跟踪了代码，可以确认在所有经过测试的设备上都调用了finish（），但是正如我所说的，在某些设备中什么也没有发生，并且活动仍然存在。 logcat上没有错误，我完全感到困惑。
如果有人对此有所了解，请与我分享。
谢谢。

好的，让我这样解释： 我为统一游戏引擎创建了一个IAP插件（由于某些原因，我们使用了自己的购买系统）。当玩家单击“购买”按钮购买某物时，我启动了另一个活动（称为ZarinpalActivity），该活动具有两个按钮（“确认购买并取消”），以及有关玩家尝试购买的产品的一些说明。在ZarinpalActivity上，当玩家单击“取消”按钮时，我调用finish（）方法来关闭活动并返回到统一状态。它很简单，并且可以按预期工作。但是，当玩家单击“确认”按钮时，我们创建了一个支付对象，该对象需要一个回调URL（我为我的活动分配了方案和主机作为回调URL）并启动了Web浏览器页面并加载了网关支付页面。现在，在付款页面上，我单击“取消”按钮，因此付款系统将响应重定向到我的应用程序（ZarinpalActivity通过调用回调URL作为响应），因此在onCreate（）方法中，我使用getIntent（）。getData（）得到响应 我处理数据并调用finish（）方法，我希望活动将被关闭，它可在90％的设备上运行，但在某些设备上什么也不会发生。 请注意，我可以确认在所有设备上都调用了finish（），我先记录了一条消息，该消息在所有设备上都显示出来。 这是我的ZarinpalActivity：

答案 0 :(得分：0)
根据您的问题，您假设A，B和C有3个活动。
因此，您必须在完成某些工作后在活动C 中致电finish();，然后将响应返回到活动B 。
然后在活动B 中处理响应，并致电finish();。
