使用 appium-python-client 在 android 中缩放操作

Question

有人知道如何通过appium python客户端在android中缩放元素吗？

我正在使用

self.driver.zoom(self.element, percent) 但这会报错

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()

但这同样不会执行任何缩放。而是向下滚动列表。有没有人知道这里出了什么问题。

MultiAction 尝试看起来不错，但是在我手机的原生相机应用上进行了一些测试后，我能够通过在 moveTo() 之后添加 500 毫秒 wait() 来获得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()

这导致相机应用的缩放效果不错且缓慢。没有 wait() 手势太快了，并没有真正做太多。在 Github 的 Appium 文档中提到，wait() 可用于控制手势的时间：https://github.com/appium/appium/blob/master/docs/en/writing-running-appium/touch-actions.md

我在我的相机应用中将xx 和yy 设置为屏幕中间：

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

请记住，坐标不应超出设备屏幕边界，因此如果您想将其变为可重用函数，检查屏幕边界可能很有用。

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