I am developing an application in which i m having four tabs.I want that on click of each tab,action bar should change.Right now I have given action bar title,search bar and overflow icon.But I want to change action bar on selection of each tab so that I can add icon in action bar according to requirement on selection of corresponding tab.

Here is my code of ontabselection,please suggest what can I do.Any help is acceptable.

public void onTabSelected(Tab tab, FragmentTransaction ft) {
            // TODO Auto-generated method stub


            FragmentTransaction fragMentTra;
            if (tab.getText().equals("DEALS")) {
                try {
                    rl.removeAllViews();
                } catch (Exception e) {
                }

                ActionBar actionBar = getActionBar();
                actionBar.show();
                actionBar.setTitle("Deals");

                FragmentDeals Fram1 = new FragmentDeals();
                //fragMentTra.addToBackStack(null);
                fragMentTra = getFragmentManager().beginTransaction();
                fragMentTra.add(rl.getId(), Fram1);
                fragMentTra.commit();
            }
            else if (tab.getText().equals("ORDER")) {
                try {
                    rl.removeAllViews();
                } catch (Exception e) {
                }

                ActionBar actionBar = getActionBar();
                actionBar.show();
                actionBar.setTitle("Order");
                FragmentOrder Fram2 = new FragmentOrder();
                //fragMentTra.addToBackStack(null);
                fragMentTra = getFragmentManager().beginTransaction();
                fragMentTra.add(rl.getId(), Fram2);
                fragMentTra.commit();
            }

            else if(tab.getText().equals("CART")){
                try {
                    rl.removeAllViews();
                } catch (Exception e) {
                }

                ActionBar actionBar = getActionBar();
                actionBar.show();
                actionBar.setTitle("Shopping Cart");
                FragmentCart fram3 = new FragmentCart();
                //fragMentTra.addToBackStack(null);
                fragMentTra = getFragmentManager().beginTransaction();
                fragMentTra.add(rl.getId(), fram3);
                fragMentTra.commit();
            }



            else if(tab.getText().equals("HISTORY")){
                try {
                    rl.removeAllViews();
                } catch (Exception e) {
                }
                ActionBar actionBar = getActionBar();
                actionBar.show();
                actionBar.setTitle("History");
                FragmentHistory fram4 = new FragmentHistory();
                //fragMentTra.addToBackStack(null);
                fragMentTra = getFragmentManager().beginTransaction();
                fragMentTra.add(rl.getId(), fram4);
                fragMentTra.commit();
            }

        }

Thanks.

Something similar to Poutrathor, but clearer for me. I got it from here: https://stackoverflow.com/a/15218201/1887635

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.fragment_xxx, menu);
}

I see you are using fragments to do your tabs. QUite easily you can declare a menu.xml file for each fragment. Using sethasOptionmenu(true) in the oncreate of your fragment. Then you can adjust stuff if needed in onCreate Option menu().

Edit : here an example : 

    @Override
public void onCreate(Bundle arg0) {
    super.onCreate(arg0);
    setHasOptionsMenu(true);
    actionBar = ((ActionBarActivity)getActivity()).getSupportActionBar();
}
@Override 
public void onCreateOptionsMenu(android.view.Menu menu, android.view.MenuInflater inflater) {
    if (!hideOptionsMenu) {
        Log.e(TAG, " - onCreateOPTIONMenu");        
        inflater.inflate(R.menu.booking_accepted, menu);
        MenuItem cancel  = menu.findItem(R.id.cancel_booking_accepted);
        cancel.getIcon().setAlpha(Constants.ENABLED_OPACITY);
        menu.findItem(R.id.my_trips_switch).getIcon().setAlpha(Constants.ENABLED_OPACITY);
    }
    // (optional) reference to a OnItemSelectedListener, that you can use to perform actions based on user selection
}
