lost fragment when orientation changed

Question

I had a problem when I change orientation of fragment. I had only one activity with some fragments. Activity run fragment1 => fragment1 run fragment 2 So when I change orientation of fragment 2, I found the activty. what I did :

I add this line to all the fragments :

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // retain this fragment
        setRetainInstance(true);
        }

and in activity onCreate I did this :

    FrameLayout frameLayout = (FrameLayout) findViewById(R.id.fragmentLayout);
    findViewById(R.id.fragmentLayout).setVisibility(View.VISIBLE);
    Map<String, Object> map = (HashMap<String, Object>) getLastCustomNonConfigurationInstance();
    // Check if we are restoring the activity from an orientation change
    // for example
    if (map == null || map.isEmpty()) {
        extras = getIntent().getExtras();
        if (extras != null && extras.getInt("CategoryId") >0 ) {

            fragment2 itemsFragment = new fragment2();

            fragment2.setArguments(extras);

            SplashActivity.this
                    .getSupportFragmentManager()
                    .beginTransaction()
                    .replace(R.id.fragmentLayout, itemsFragment).addToBackStack("fragment2").commit();
        }
    }

so my question, how I can change orientation of fragment 2 and stay in fragment2 ?
