i know that there are many many response about my question , but i precise that i am making application where any interact on status bar are allow. So , i want to hide the status bar. I already use :
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_HIDE_NAVIGATION);
the status bar disappear at first but when i interact with the view, he come back and i wish it were blocked.
How I do it ?
You should create a fullScreen Acivity i. e. You must add these lines in Your OnCreate method
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
and then setContentView(R.layout.MainActivity);
