如何在android上的ClickListener上调用开关内的itemclicklistener

我正在创建一个android应用程序。我想要的是，当用户单击一行中的开关时，它调用listview的监听器。以前，我试图在customAdapter内的交换机onclicklistener上调用listview的itemclicklistener，但它抛出了一个错误。如果我无法达到我想要的结果，请告诉我另一种方法。如果您想知道为什么我需要在交换机的onclick中调用listview的itemclick，那是因为itemclick是我获取行id的唯一方法，我将使用它来更新行

提前谢谢。：）

以下是具有listview的活动的代码：

为什么需要触发交换机侦听器？为了只获取正确的开关状态？显示活动的xml，您可以删除适配器代码段，它没有用。我想要获取的是id和状态。我想要的是开关被用作开关，而不仅仅是显示状态的东西。此外，如果交换机能够更改设备的状态而不是listview本身，则更符合逻辑。
