这不是Android系统的功能.设备制造商(例如您提到的小米)或启动器开发人员(例如 Nova启动器)可以实现它并为应用程序开发人员公开一个api，但是对此没有标准，用户也不希望它存在.

This is not a feature the of Android system. Device manufacturers (like Xiaomi you mentioned) or launcher developers (like Nova Launcher) can implement it and expose an api for app developers, but there is no standard for that, nor is it expected by the users to be there.

通常，您不应尝试在Android上执行此操作.
