一、问题
自动翻译res/values/strings.xml

二、解决
本来想注册google 翻译api，不通过。（信用卡通过，身份证验证不通过，谁有办法？）
现在用百度翻译api，官网https://fanyi-api.baidu.com/product/113

如何使用通用翻译API？

1. 使用您的百度账号登录百度翻译开放平台；
2. 注册成为开发者，获得 APPID ；
3. 进行开发者认证（如仅需标准版可跳过）；
4. 开通通用翻译API服务：开通链接；
5. 参考技术文档和 Demo 编写代码。

三、例子

python.exe .\test_xml_translate_main.py .\out\strings.xml

生成 .\out\strings_translate.xml
英语字符，被翻译成中文字符

例子简单粗糙，记录一下，备忘。
