推荐答案

一个wakelock给你的方式更多的控制（像唤醒手机下载的东西，而不转动屏幕关闭），并要求您的应用程序保持wakelock权限。

A wakelock gives you way more control (Like waking the phone to download something without turning the screen off) and requires your application to hold the wakelock permission.

因此​​ FLAG_KEEP_SCREEN_ON 建议如果你想要的是保持在屏幕上，而你的窗口是可见的。

Therefore FLAG_KEEP_SCREEN_ON is recommended if all you want is to keep the screen on while your window is visible.
