检测屏幕截图 Android [英] Detect a screenshot Android

问题描述

我近年来对 Android 进行编程，我想知道一些事情:如何检测用户何时截屏?我希望当用户截取屏幕截图时，我们移动到下一个活动.我尝试了拦截事件的方法，但是有一个问题:例如，当设备进入睡眠状态时，会拦截一个事件.有没有只截取截图事件或者忽略其他事件的解决方案?

I program in recent years to Android and I wonder something : How to detect when user take a screenshot ? I want that when the user takes a screenshot , we move to the next activity . I tried the method of intercepting an event but there is a problem : when the device goes into sleep , for example, an event is intercepted . Do you have a solution for intercepts only the event of screenshot or ignore other event?

感谢您的帮助！

推荐答案

没有直接的 Broadcast Intent 告诉您已截取屏幕截图.有些人这里讨论了可能的选项(就像在快照).一种可能的选择是使用 FileObserver.

There is no direct Broadcast Intent to tell you that a screenshot has been taken. Some people here discuss possible options to do so ( like it's done on Snapchat ). One possible option would be to use FileObserver.
