Android Show Activity Title/status bar at the top after it is hidden

Question

Currently in my FragmentActivity, I hide the status bar by, in the onCreate method, doing the following:

 requestWindowFeature(Window.FEATURE_NO_TITLE);
 getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);

this works no problem.

But in full screen, say user clicks a button, I will want to swap in another fragment (remember we are in FragmentActivity), I mean replacing the currently fragment that is displayed in full screen.

but I want the titlebar/status to be shown.

Is this possible? If so, how can I do it programmatically

Here you can change your title bar dynamically using following two methods. I called them from my Activity. So to call from Fragment you need the Activity instance.

public void hideTitle() {
        try {
            ((View) findViewById(android.R.id.title).getParent())
                    .setVisibility(View.GONE);
        } catch (Exception e) {
        }
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
        getWindow().clearFlags(
                WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
    }

    public void showTitle() {
        try {
            ((View) findViewById(android.R.id.title).getParent())
                    .setVisibility(View.VISIBLE);
        } catch (Exception e) {
        }
        getWindow().addFlags(
                WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
        getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    }
