代码调用如下：
baidu_map=driver.find_element_by_id('com.baidu.BaiduMap:id/f6')
driver.zoom(baidu_map)
方法定义：
def zoom(self, element=None, percent=200, steps=50):
"""Zooms in on an element a certain amount
:Args:
- element - the element to zoom
- percent - (optional) amount to zoom. Defaults to 200%
- steps - (optional) number of steps in the zoom action
:Usage:
driver.zoom(element)
"""
if element:
element = element.id
opts = {
'element': element,
'percent': percent,
'steps': steps,
}
self.execute_script('mobile: pinchOpen', opts)
return self
运行结果：

经过谷歌 + 百度也没找到相关解决方案，查看了一下 appium 官方论坛也有人反馈这个缩放操作不生效：How To Zoomin And Zoom Out Using Appium
请问楼主有相关文章吗？有的话请贴下关于原理图讲解的文章，想学习下
目前使用了一种替代方案实现了缩放，结合 MultiAction 和 TouchAction。
滑动原理图解
x = driver.get_window_size()['width']
y = driver.get_window_size()['height']
# 放大
def zoom():
action1 = TouchAction(driver)
action2 = TouchAction(driver)
zoom_action = MultiAction(driver)
action1.press(x=x*0.4, y=y*0.4).move_to(x=x*0.1, y=y*0.1).wait(500).release()
action2.press(x=x*0.6, y=y*0.6).move_to(x=x*0.8, y=y*0.8).wait(500).release()
print('start zoom...')
zoom_action.add(action1, action2)
zoom_action.perform()
# 缩小
def pinch():
action1=TouchAction(driver)
action2=TouchAction(driver)
pinch_action=MultiAction(driver)
action1.press(x=x*0.1, y=y*0.1).move_to(x=x*0.4, y=y*0.4).wait(500).release()
action2.press(x=x*0.8, y=y*0.8).move_to(x=x*0.6, y=y*0.6).wait(500).release()
print("start pinch...")
pinch_action.add(action1, action2)
pinch_action.perform()
