How to create fragments using setArguments / getArguments

I create tabs in my application using information from the epidemic response

I created a main class that processes tabs, this class extends TabActivitycreates tabs:

    Resources res = getResources();
    TabHost tabHost = getTabHost();
    TabHost.TabSpec spec;  
    Intent intent;

    intent = new Intent().setClass(this, stackA.class);    
    spec = tabHost.newTabSpec("tab1").setIndicator("Tab 1",
                      res.getDrawable(android.R.drawable.ic_menu_search))
                  .setContent(intent);
    tabHost.addTab(spec);

    intent = new Intent().setClass(this, stackB.class);
    spec = tabHost.newTabSpec("tab2").setIndicator("Tab 2",
                      res.getDrawable(android.R.drawable.ic_menu_search))
                  .setContent(intent);
    tabHost.addTab(spec);
    tabHost.setCurrentTab(0);

Then, a FragmentActivity is created for each tab, and this makes it possible to create a stack on each tab. My fragments are created:

protected void navigateTo(Fragment newFragment) {
    FragmentManager manager = getSupportFragmentManager();
    FragmentTransaction ft = manager.beginTransaction();
    ft.replace(R.id.content, newFragment);
    ft.addToBackStack(null);
    ft.commit();
}  

public class fragmentA extends Fragment{
    private LinearLayout ll;
    private FragmentActivity fa;

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    fa = super.getActivity();
    ll = (LinearLayout) inflater.inflate(R.layout.fragmenta, container, false);
    Button next = (Button) ll.findViewById(R.id.button1);
    next.setOnClickListener(new View.OnClickListener() {
        public void onClick(View view) {
            ((ActivityInTab) getActivity()).navigateTo(new fragmentB());
        }
    });
    return ll;
    }
}

It works. What's wrong is that when I'm on tab 1 and fragment B (the first fragment on the stack is A), rotate my device and then return it to fragment A.

Epidian said something about orientations and used setArguments / getArguments, but I'm new to Android programming, so I really don't know how to do this:

, , setArguments/getArguments. , . , , : setArguments , getArguments onCreate, .

int x;

Bundle args = new Bundle();

args.putString("variable", x);

FragmentManager fragmentManager = getFragmentManager();

FragmentTransaction ft = fragmentManager.beginTransaction();

Fragment fragment = Fragment.instantiate(getActivity(), MyFragment.class.getName(), args);

ft.replace(R.id.layout1, fragment);

ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);

ft.addToBackStack(null);

ft.commit();

:

getArguments().getInt("variable");

You can use Fragment.setRetainInstance(true)for this. See this related question .
