Hide/show status and navigation bar on

I am searching for hours, but nothing found.
I just want to hide/show status and navigation bar when I hit the screen, like android gallery.
// Hide status bar
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
// Show status bar
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
The code above works fine for Status bar, but what about navigation bar (bottom bar) like android gallery? (I dont want to use 4.4 immersive mode)

Hide/ Show notification bar in android

I am able to hide notification bar using this code
setWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
But I want the user to have an option to show and hide notification bar.
Currently my Activity permanently hides the notification bar.
How cam I do it?

You can exit full screen mode (i.e. show status bar) by using:
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
