Question

我想做什么？ - 基本上我想在特定时间在特定的X，Y坐标上实用地进行人体触摸 - 运行一个服务，通过某个接口（TCP / UDP）接收X，Y坐标 - 使用这些坐标消防dispatchTouchEvent（）并获得实际人手指点击给出的结果 - 我的意思是焦点活动可能是Android主屏幕或任何打开的活动或任何东西 - moment服务调用dispatchTouchEvent（），它应该执行单击。 - 例如，如果打开App是计算器，并且dispatchTouchEvent（）的X，Y坐标指向数字5，则应按5键

我现在做了什么？ - 我已经开始接收X，Y坐标的服务 - 在某些触发器上，它调用dispatchTouchEvent（），但它不起作用。它不会点击屏幕上的任何内容。 - 它捕捉人类手指所做的每一次触摸事件。

问题是什么？ - 如何将dispatchTouchEvent（）发布到任何底层活动

示例代码： 我在这里附上示例代码。我刚刚将它简化为测试目的。首先，我们需要点击屏幕中的任意位置。将保存其X，Y坐标，并在一段时间后调用dispatchTouchEvent（）使用相同的坐标。
