python uiautomator 类型错误 : 'AutomatorDeviceObject' object is not callable

Question

以上是带有属性的 uiautomator 对象查看器屏幕截图。我正在使用通过 pip install uiautomator 安装的 python 包 uiautomator。我正在尝试通过 UI 自动化对象访问三点设置按钮。我尝试使用 https://github.com/xiaocong/uiautomator#handler 中列出的文档

这是代码和错误:

d = uia.device() #below all are my attempts

经过所有尝试，我仍然无法访问任何 UI 对象。请让我知道我在这里缺少什么？

更改:

import uiautomator as uia
d = uia.device()

致:

import uiautomator as uia
d = uia.device

这应该可以解决您的问题。

发生这种情况是因为您在变量内调用函数 device() 。所以“d”不是一个函数，而是使用一个函数来接收一个值。

当我们使用括号调用函数时，Python 知道我们正在调用它并在变量“d”上使用此结果。这就是您面临“对象不可调用”的原因，因为没有对象作为参数传递给“device()”。

当我们不使用括号时，我们不会调用该函数，而是对其进行引用，并且在调用它时将传递参数。

希望对你有帮助!
