python uiautomator TypeError：'AutomatorDeviceObject'对象不可调用

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。我试图通过UI自动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

以下是代码和错误：

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

在所有尝试之后，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？

Answer 1

变化：

import uiautomator as uia
d = uia.device()

要：

import uiautomator as uia
d = uia.device

这可以解决您的问题。

这是因为你在变量中调用函数device（）。所以“d”不是函数，而是使用函数来接收值。

当我们使用括号调用函数时，Python理解我们正在调用它并在变量“d”上使用此结果。这就是为什么你面对“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调用函数，我们引用它，当我们调用它时参数将被传递。

希望它有所帮助！

Answer 2

不是您的问题的解决方案，而是替代方案：使用AndroidViewClient/culebra您可以运行

culebra -uG -o camera-options.py

有了窗口，您可以点击选项点

立即查看结果

同时，将生成包含重现此操作的代码的脚本
