解决方法：
from appium.webdriver.common.appiumby import AppiumBy # 导入AppiumBy
search = driver.find_element(AppiumBy.ID,"com.android.settings:id/search") # 编写格式：driver.find_element(by=AppiumBy.ACCESSIBILITY_ID, value='accessibility_id')
思考流程：
1.敲代码时，编辑器已经标黄提示无find_element_by_id，当时以为是敲错，复制了正确的代码运行，报“AttributeError: 'WebDriver' object has no attribute 'find_element_by_id'”
2.查看网上解决方案，有人提到现在的版本不支持find_element_by_id，目前写法为driver.find_element(By.ID,"com.android.settings:id/search")，修改后运行，仍然报错
3.ctrl+查看find_element方法，直接复制注释中的driver.find_element(by=AppiumBy.ACCESSIBILITY_ID, value='accessibility_id')，AppiumBy报错
4.找到https://blog.csdn.net/fsafd3321/article/details/127096420博客中的解决方法，尝试后，能成功运行。但是解决思路中，提到的文件中搜索关键词这步不会
5.反推第三步，应该这样看，ctrl+查看find_element方法，然后由于AppiumBy报错，应该再点击查看find_element中的AppiumBy类，或全文搜索AppiumBy可看到导入的
from appium.webdriver.common.appiumby import AppiumBy
