It actually depends on the version of android you are using. For example in Android 4.0 and lower you can achieve it by doing:

<application
...
android:theme="@android:style/Theme.Holo.NoActionBar.Fullscreen" >
...
</application>

For full documentation go to: https://developer.android.com/training/system-ui/status

Edit: What would be better for your button is this code: 

void HideStatusBar() {
     View decorView = getWindow().getDecorView();
     // Hide the status bar.
     int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
     decorView.setSystemUiVisibility(uiOptions);
     // Remember that you should never show the action bar if the
     // status bar is hidden, so hide that too if necessary.
     ActionBar actionBar = getActionBar();
     actionBar.hide();
}

So, when the user clicks the button call this function. Remember this also hides the action bar or toolbar, so if you don't want that remove the actionbar.hide() part. It's nice, but unfortunately, it only works on Android 4.1 and higher, so if you are supporting lower versions too better look at the documentation for clues. Hope it helps!

  1. Create a superclass for all Activities, call it something like BaseActivity or AbstractActivity and make each activity extend this class
  2. In the onCreate, before setContentView, read from a database like SharedPreferences whether the status bar should be hidden. If so, then hide it.
  3. In your Settings activity, call recreate() so that each onCreate from the previous activities are called again.
