Appium [已解决] 请问如何实现长按的持续时间？( long_press duration python)

谢谢大家，不知道这是不是 Appium 的 bug，在它的 API 里面看到有一个长按的函数，但它的持续时间不知道如何调用。
搜了帖子基本上就是如何长按，但是没有长按多久。
下面是它原生的函数

def long_press(self, el=None, x=None, y=None, duration=1000):
"""Begin a chain with a press down that lasts duration milliseconds
"""
self._add_action('longPress', self._get_opts(el, x, y))

return self

我在谷歌上搜了写方法，但是还是不能实现

action = TouchAction(self.driver)
el = self.driver.find_element_by_id('XXXXX')
action.long_press(el).wait(10000).release().perform()
以上的方法仅能实现，不到 1 秒的短按，达不到长按 10 秒的效果
报的是这个错：WebDriverException: Message: u'An unknown server-side error occurred while processing the command.'

谢谢大家。第一次发帖，希望没有触犯发帖规范 ~~~~~~ ：）

driver.executeScript("mobile: tap", new HashMap<String, Double>() {
            {
                put("tapCount", (double) 1);
                put("touchCount", (double) 1);
                put("duration", 0.5);
                put("x", x);
                put("y", y);
            }
        });

如果你要調整時間的話，修改 duration 的參數即可

不是有 duration 么，只是默认参数罢了

tap 方法可以试一下

def tap(self, positions, duration=None):
        """Taps on an particular place with up to five fingers, holding for a
        certain time

        :Args:
         - positions - an array of tuples representing the x/y coordinates of
         the fingers to tap. Length can be up to five.
         - duration - (optional) length of time to tap, in ms

        :Usage:
            driver.tap([(100, 20), (100, 60), (100, 100)], 500)
        """
        if len(positions) == 1:
            action = TouchAction(self)
            x = positions[0][0]
            y = positions[0][1]
            if duration:
                duration = duration
                action.long_press(x=x, y=y, duration=duration).release()
            else:
                action.tap(x=x, y=y).release()
            action.perform()
        else:
            ma = MultiAction(self)
            for position in positions:
                x = position[0]
                y = position[1]
                action = TouchAction(self)
                if duration:
                    duration *= 1000  # we take seconds, but send milliseconds
                    action.long_press(x=x, y=y, duration=duration).release()
                else:
                    action.press(x=x, y=y).release()
                ma.add(action)

            ma.perform()
        return self

经过实践，发现不可行
不管 duration 传多少，在 UIAutomation 中 time 总是 0.2，依然是普通 Tap 的效果
Code：

self.driver.tap([(176, 86)], duration=5000)
