How to activate full screen control DOTS (SDK14)

问题

Does anybody know what i mean?

In fullscreen mode of the new camera app on my galaxy nexus the control buttons are changing into 3 dots.

How can i activate that programmatically?

回答1:

You can use

getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);

within your activity.

See View.SYSTEM_UI_FLAG_LOW_PROFILE

It's a standard Options Menu. On 3.0+ it creates those dots, in 2.3.3- you access it with the menu key.
