# 上面一行为关键一行，have two questions
# 第一点：//*[@resource-id="com.tencent.mm:id/bh"]//android.widget.RelativeLayout,这一行后面为什么不能加上[@class=],按理说android.widget.RelativeLayout并不是标签。
#那么如果改成//*[@resource-id="com.tencent.mm:id/bh"]//[@class=android.widget.RelativeLayout]可不可以？
#第二点：为什么不能用//*[@resource-id="com.tencent.mm:id/bh"][4]这种方式去索引,难道不一样吗？而自己的实验证明不成功。

# above line is the fist ID(钱包这个选项)，because id can be duplicated. this button is not the right button
# the button can run succussfully, it proved that we can click the button even thouthg the view show that the button is not clickable.
# it prove that monitor.bat is not completely right

# oh my god 居然这种方式可行，you should notice the code wait.until(EC.presence_of_all_elements_located((By.XPATH,'//*[@resource-id="com.tencent.mm:id/kl"]')))[2]
# use this code we can select element through quantation, also you should know that using By.ID[3] is not correct ,i do not know why.
# and using EC.presence_of_all_elements_located((By.XPATH,'//*[@resource-id="com.tencent.mm:id/kl"]'))[2]) is not correct eithor, because the position of the quantation is not correct 

choosePhotoAlbum.click() # click the button
print(11111111111111111111) # 只是验证程序的进程
time.sleep(10) # sometimes the phone is very slow , wait the phone refresh.

resultList = [] # create a empty list
for i in downloadInformation:
    word = i.get_attribute("text") # obtain the text in every tag
    resultList.append(word) # add the text to the list

print(resultList)

# com.tencent.mm:id/jv
# com.tencent.mm:id/mi 有表情
# com.tencent.mm:id/jv 只有表情
# com.tencent.mm:id/jv 基本上就只有这两个

第一个坑：要安装上python,安装上selenium,安装上appium, 以上三个都是基于python的。其次安装appium客户端，安装
