使用appium-python-client在android中缩放动作

Question

有没有人知道如何通过appium python客户端缩放android中的元素？

我目前正在使用

self.driver.zoom(self.element, percent) 但这会给出错误

self.driver.zoom(self.element, percent)
File "/usr/local/lib/python2.7/site-packages/appium/webdriver/webdriver.py", line 308, in zoom
self.execute_script('mobile: pinchOpen', opts)
File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 461, in execute_script
{'script': script, 'args':converted_args})['value']
File "/usr/local/lib/python2.7/site-packages/selenium/webdriver/remote/webdriver.py", line 233, in execute
self.error_handler.check_response(response)
File "/usr/local/lib/python2.7/site-packages/appium/webdriver/errorhandler.py", line 29, in check_response
raise wde
WebDriverException: Message: Method has not yet been implemented

我也试过了MultiAction.

loc = self.element.location
print loc
xx, yy = loc["x"], loc["y"]
xx=700
action1 = TouchAction(self.driver)
action1.long_press(x=xx, y=yy).move_to(x=0, y=1000).release()
action2 = TouchAction(self.driver)
action2.long_press(x=xx, y=yy).move_to(x=0, y=-1000).release()
m_action = MultiAction(self.driver)
m_action.add(action1, action2)
m_action.perform()

但是这再次没有执行任何缩放.相反它向下滚动列表.是否有人知道这里有什么问题.

MultiAction 尝试看起来不错，但在我手机的本机相机应用程序上进行了一些测试后，我通过在 moveTo() 之后添加 500ms wait() 获得了一个不错的缩放手势：

# Zoom
action1.long_press(x=xx, y=yy).move_to(x=0, y=50).wait(500).release()
action2.long_press(x=xx, y=yy).move_to(x=0, y=-50).wait(500).release()
m_action.add(action1, action2)

# Pinch
action3.long_press(x=xx, y=yy-50).move_to(x=0, y=50).wait(500).release()
action4.long_press(x=xx, y=yy+50).move_to(x=0, y=-50).wait(500).release()
m_action2.add(action3, action4)

m_action.perform()
m_action2.perform()

这导致相机应用程序的变焦效果良好且缓慢。如果没有 wait()，手势太快并且没有真正做太多事情。Github 上的 Appium 文档提到，wait() 可用于控制手势的时间：https://github.com/appium/appium/blob/master/docs/en/writing-running-appium/触摸动作.md

xx我在相机应用程序中将和设置yy为屏幕中间：

xx = self.driver.get_window_size()['width']/2
yy = self.driver.get_window_size()['height']/2

请记住，坐标永远不应该超出设备屏幕边界，因此如果您想将其变成可重用的函数，则检查屏幕边框可能很有用。

在自动化 Chrome 时，我也无法使用 MultiAction 手势（即使更改为 NATIVE_APP 上下文也无法使用。手势没有任何效果。），因此可能不支持在 WebView 场景中使用 MultiActions。
