android - Dismiss or remove System Navigation Bar -

i want dismiss bottom navigation bar 1 particular screen. tried using

setsystemuivisibility(horizontalscrollview.system_ui_flag_hide_navigation); 

i have put in onscroll of scrollview, ontouch of views. issue comes , screen gets resize.

any suggestions can remove navigation bar.

check out system_ui_flag_hide_navigation, flag hides navigation bar until user interacts device. it's new in android 4.0. can enable flag example this:

getwindow().getdecorview()            .setsystemuivisibility(view.system_ui_flag_hide_navigation); 

note navigation won't disappear again automatically, have set every time after user interacted device.

alternatively can make navigation less obtrusive using system_ui_flag_low_profile, changes buttons small dots (e.g. camera app).
