我正在为具有地图屏幕的Android应用程序进行自动化测试。在那个屏幕上，我想放大和缩小。我无法让它发挥作用。是的，我已经阅读了这里的回复[1]并且它不起作用。以下是我的尝试。
继续在地图上工作：
# Move south on the map
move_south = TouchAction(driver)
move_south.press(x=map_center_x, y=map_center_y).wait(100) \
.move_to(x=map_center_x, y=map_center_y-200).wait(100).release()
move_south.perform()
# Move north on the map
move_north = TouchAction(driver)
move_north.press(x=map_center_x, y=map_center_y).wait(100) \
.move_to(x=map_center_x, y=map_center_y+200).wait(100).release()
move_north.perform()
放大（使用两根手指）没有做任何事情（没有错误，没有地图移动）：
# Zoom in - two fingers
move_south = TouchAction(driver)
move_south.press(x=map_center_x, y=map_center_y).wait(100) \
.move_to(x=map_center_x, y=map_center_y-200).wait(100).release()
move_north = TouchAction(driver)
move_north.press(x=map_center_x, y=map_center_y).wait(100) \
.move_to(x=map_center_x, y=map_center_y+200).wait(100).release()
zoom_in_2_fingers = MultiAction(driver)
zoom_in_2_fingers.add(move_south)
zoom_in_2_fingers.add(move_north)
zoom_in_2_fingers.perform()
以下是Appium日志：

缩小（使用两根手指）不会抛出错误，但地图会变成空白（？）：
# Zoom out - two fingers
move_south = TouchAction(driver)
move_south.press(x=map_center_x, y=map_center_y+200).wait(100) \
.move_to(x=map_center_x, y=map_center_y).wait(100).release()
move_north = TouchAction(driver)
move_north.press(x=map_center_x, y=map_center_y-200).wait(100) \
.move_to(x=map_center_x, y=map_center_y).wait(100).release()
zoom_out_2_fingers = MultiAction(driver)
zoom_out_2_fingers.add(move_south)
zoom_out_2_fingers.add(move_north)
zoom_out_2_fingers.perform()
放大（使用单指手势，点击然后向下拖动）放大，但偏离中心（这很奇怪，因为无论我在模拟器上用鼠标重复此手势，都会发生缩放在地图上的中心点附近）：
# Zoom in - one finger
zoom_in_1_finger = TouchAction(driver)
zoom_in_1_finger.press(x=map_center_x, y=map_center_y).wait(100).release()\
.press(x=map_center_x, y=map_center_y).wait(100)\
.move_to(x=map_center_x, y=map_center_y+200).wait(100).release()
zoom_in_1_finger.perform()
缩小（一根手指）实际上放大，再次偏离中心：
# Zoom out - one finger
zoom_out_1_finger = TouchAction(driver)
zoom_out_1_finger.press(x=map_center_x, y=map_center_y).wait(100).release()\
.press(x=map_center_x, y=map_center_y).wait(100)\
.move_to(x=map_center_x, y=map_center_y-200).wait(100).release()
zoom_out_1_finger.perform()

有人能帮我理解发生了什么吗？
我正在使用Appium v1.8.0，Python 3.5，Python-Appium v0.26和运行Android 6.0的模拟器。
