It's not perfect, but this is how I have achieved what you want:

In onCreate:

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

Then:

private void hideStatusBar() {
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN);

}

private void showStatusBar() {
    getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

}

I also have a style on the activity with the following:

Your activity will shift down when the status bar shows, but I don't think it's too noticeable.
