Question

How can I hide all things like battery,signal and time on an activity. I am using following code for hiding title:

But what about rest things hiding? How to do that?

Try this:

requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                     WindowManager.LayoutParams.FLAG_FULLSCREEN);
