Act as a professional Python coder. You are one of the best in your industry and currently freelancing. Your task is to create a Python script that works on an Android phone using Pydroid 3.
Your script should:
- Provide a menu with options for checking updates: system updates, security updates, Google Play updates, etc.
- Allow the user to check for updates on all options or a selected one.
- Display updates available, let the user choose to update, and show a progress bar with details such as update size, download speed, and estimated time remaining.
- Use colorful designs related to each type of update.
- Keep the code under 300 lines in a single file called `app.py`.
- Include comments for clarity.
Here is a simplified version of how you might structure this script:
```python
# Import necessary modules
import os
import time
from some_gui_library import Menu, ProgressBar
# Define update functions
def check_system_update():
# Implement system update checking logic
pass
def check_security_update():
# Implement security update checking logic
pass
def check_google_play_update():
# Implement Google Play update checking logic
pass
# Main function to display menu and handle user input
def main():
menu = Menu()
menu.add_option('Check System Updates', check_system_update)
menu.add_option('Check Security Updates', check_security_update)
menu.add_option('Check Google Play Updates', check_google_play_update)
menu.add_option('Check All Updates', lambda: [check_system_update(), check_security_update(), check_google_play_update()])
while True:
choice = menu.show()
if choice is None:
break
else:
choice()
# Display progress bar and update information
progress_bar = ProgressBar()
progress_bar.start()
# Run the main function
if __name__ == '__main__':
main()
```
Note: This script is a template and requires the implementation of actual update checking and GUI handling logic. Customize it with actual libraries and methods suitable for Pydroid 3 and your specific needs.扮演一名专业的 Python 程序员。你是行业中最顶尖的人才之一，目前是一名自由职业者。你的任务是使用 Pydroid 3 编写一个可在安卓手机上运行的 Python 脚本。
你的脚本应当：
- 提供一个菜单，包含系统更新、安全更新、Google Play 更新等检查选项。
- 允许用户一次性检查所有选项的更新，或只检查选定的一项。
- 显示可用的更新，让用户选择是否更新，并显示进度条，附带更新大小、下载速度、预计剩余时间等详细信息。
- 针对每种类型的更新使用相应的彩色样式。
- 代码控制在 300 行以内，放在一个名为 `app.py` 的单文件中。
- 包含清晰易懂的注释。
以下是该脚本可能结构的简化示例：
```python
# 导入必要的模块
import os
import time
from some_gui_library import Menu, ProgressBar
# 定义更新函数
def check_system_update():
# 实现系统更新检查逻辑
pass
def check_security_update():
# 实现安全更新检查逻辑
pass
def check_google_play_update():
# 实现 Google Play 更新检查逻辑
pass
# 显示菜单并处理用户输入的主函数
def main():
menu = Menu()
menu.add_option('检查系统更新', check_system_update)
menu.add_option('检查安全更新', check_security_update)
menu.add_option('检查 Google Play 更新', check_google_play_update)
menu.add_option('检查所有更新', lambda: [check_system_update(), check_security_update(), check_google_play_update()])
while True:
choice = menu.show()
if choice is None:
break
else:
choice()
# 显示进度条和更新信息
progress_bar = ProgressBar()
progress_bar.start()
# 运行主函数
if __name__ == '__main__':
main()
```
注意：该脚本只是一个模板，需要实现实际的更新检查和 GUI 处理逻辑。请根据 Pydroid 3 和你的具体需求，使用合适的真实库与方法来完成定制。
