是否可以阻止Android <4.4上的导航栏？

Question

In my application I want to prevent the display of the navigation bar. In Android 4.4 it's easy to implement (see here: How to hide navigation bar permanently in android activity? ), but lower versions can't do this.

I saw a similar mechanism in some players which hide navigation bar in fullscreen without any possibility to display it when the screen is touched.

I would be grateful for tips or code samples as it can be done.

Thank you.

SYSTEM_UI_FLAG_HIDE_NAVIGATION is available since API level 16. So it works since Android 4.1+. You have to remember to reset this flag every time the user makes the NavigationBar show up again.

Only the immersive mode is only available since 4.4
