window_handle()

list的方式拿到的元素个数总数为0，很奇怪

  你去找开发确认一下你们那个是不是就是一张图片。这个时候你可以通过adb命令点击

你好，你是不是可以通过list进行定位，然后按照index去呢

• 提问者 夏目鲸鱼 #1

  尝试过用以下两种方式，但是得到的列表都是空列表，这个很奇怪的。
  # step_in = driver.find_elements_by_class_name('android.widget.Button')
  # step_in[1].click()
  
  find_elements_by_xpath:
  route_in = "//android.widget.Button[contains(@content-desc, '进入')]"
